Windows Explorer restarts. Correction of errors with the program explorer

Many computer users at least once met with a situation where, when working on a PC, it hung "Conductor". Much worse when such problems occur regularly. Let's find out what are the ways to resume the normal operation of this important element in the operating room. Windows system 7.

The most intuitive option to resume a hung "Explorer" is to restart the computer. Many users do this when this problem occurs. But at the same time, all documents and programs that were minimized at the time of the problem will be forced to close, which means that the changes made to them will not be saved. This option does not suit us, and therefore we will consider a method to get out of this situation without having to restart the PC. It will also explore ways to address the root causes of operational problems. "Explorer".

Method 1: "Task Manager"

One of the easiest options to resume the functioning of a hung "Explorer" is the application "Task Manager". This tool forces the termination of the EXPLORER.EXE process and then restarts it.

The most common option that users use to open "Task Manager" executed via the context menu "Dashboards". When hung "Explorer" this method will not work. But the method with the use of "hot" keys will fit quite well. So get a combo Ctrl+Shift+Esc.
"Task Manager" will be launched. Move to tab "Processes".

In the list that appears on the plane of the window that opens, you should find an element called EXPLORER.EXE. If there are a lot of processes running on the computer, then finding the named object will not be so easy. To make things easier, you can build all the elements in alphabetical order. To do this, click on the column name "image name".

After finding the object you are looking for, select it and press "End Process".

A dialog box opens asking you to confirm your decision. Click "End Process".

After that, all panels, icons on "Desktop" and open windows will disappear. Don't be alarmed, as it's normal for the EXPLORER.EXE process to be forcefully terminated, causing the operation to stop "Explorer". Now our task is to restore its functioning. In the window "Task Manager" press "File". In the list that opens, stop the selection on the item "New Task (Run...)".

A window opens "Create a new task". Enter the command in its only field:
Click OK.

"Conductor" restarts. Now its work and functionality will be fully restored.

Method 2: Update the graphics card driver

The above method of solving the problem is good for a single manifestation of it. But when the situation repeats itself again and again, this means that you need not to deal with the consequences, but to look for the root cause of the problems. It may consist, for example, in the failure of the video driver. Let's see how to fix this situation.

click button "Start". Come in "Control Panel".

Now click "System and safety".

In the window that appears in the group "System" click item "Device Manager".

A window appears "Device Manager". Click on the name of the group "Video Adapters".

A list of devices opens, among which there must be the name of the video card connected to your computer. Double-click on the name of this element with the left mouse button.

The properties window for the selected device opens. Move to tab "Driver".

Next click on the button "Delete" at the very bottom of the window that opens.

After the object is deleted, you need to produce . The found file should be downloaded and installed on a PC. If you do not want to perform the search and installation operation manually, this task can be entrusted to specialized programs, in particular.

Method 3: Troubleshoot low RAM issues

Another reason why it hangs "Conductor", it may be that your computer simply does not have enough hardware resources to process all the tasks that you have loaded it with. So individual components systems begin to slow down or fail. Especially often this problem is encountered by users of low-power computers who have a very limited amount of RAM or a weak processor. Let's figure out what to do in this case.

Certainly, The best way to radically solve the current problem is to buy a more powerful processor or purchase an additional “RAM” bar. But unfortunately, not everyone is ready to take these measures, and therefore we will figure out what needs to be done to freeze "Explorer" occurs as infrequently as possible, but do not replace hardware components.

In the future, to avoid freezing "Explorer" For similar reasons, try to avoid running multiple resource-intensive programs at the same time, as well as those applications that you do not need when starting the computer. Also recommended.

Method 4: Disable thumbnail displays

One of the causes of freezing problems "Explorer", is the incorrect display of image thumbnails. When downloading images from the Internet, some of them may not be completely downloaded, which leads to incorrect display of their thumbnails, as a result of which malfunctions begin "Explorer". To completely eliminate this option problems, you can simply turn off the thumbnail display on the PC.

Now if the cause of constant freezing "Explorer" there was an incorrect display of thumbnails, the indicated problem will no longer bother you.

Method 5: Eliminate the virus infection

The next reason that can cause unstable operation "Explorer", is a virus infection of the computer. Recommended in case of frequent freezing this component system, even in the absence of other signs of infection, . It certainly won't be redundant. You can apply either similar program which does not require installation. It is better to check from another PC or by running the system via LiveCD.

If virus activity is detected, the program will notify the user about it and offer best option troubleshooting. After getting rid of the root cause, work "Explorer" should get better.

Method 6: System Restore

But there are cases when viruses or other external factors have already managed to damage system files, which ultimately results in unstable work "Explorer". Then the system needs to be restored. Depending on the complexity of the problem that has arisen and on the previously carried out preventive measures, the following actions can be taken to eliminate it:

In this article, we have elaborated on the main reasons why "Conductor" freezes. As you can see, they can be very diverse. In addition, figured out how quickly it can be returned to operational state, and also figured out how to eliminate the root cause of the malfunction, if these kinds of problems occur regularly, depending on what exactly caused them.

Explorer is an application that allows you to navigate from one section using a visual interface hard drive to another to search for elements. Mistake terminated work explorer occurs in rare cases and provokes an emergency closure of the application.

Why did File Explorer stop working?

Windows Explorer stops working for several reasons, mainly this reaction provokes separate program. At the moment of contacting her as a guide, she is not available and acts as the root of the problem. A malfunction can be expressed in one-time failures, so the conductor knocks out infrequently, then it is quite difficult to determine the source. In other cases, every time the application is opened, an error occurs.

Windows Explorer 7 and other versions stop working such malfunctions:

Integrated context menu elements;
Faulty codecs, mostly video codec;
Elements included in the control panel;
Rarely, but the reason lies in the video adapter;
Sometimes the File Explorer process gets corrupted due to viruses.

Any reason is relevant and can significantly harm the conductor. The breakdown should be diagnosed and eliminated one by one.

File Explorer has stopped working: fixing the context menu

Windows 7 Explorer has stopped working, how to fix it if the error lies in context menu? - You should return it to its basic state, that is, remove all secondary applications, most often this will be the answer.

The easiest way to accomplish the task is to use the ShellExView utility. The application shows programs that have a contextual display.

In the main menu of the program, sort the parameters by "Type";

Find everything that is in the nature of the "Context Menu";
Disable all elements in the path that have an asterisk using RMB or F7, except for Microsoft;
Reboot and check the result.

If the expected result does not follow, disable other items, but be sure to leave the processes produced by Microsoft, all the rest can be disabled. We'll have to use the selection method to identify and fix the problem.

You can also check that the problem is in minor utilities using safe mode. You can go to it by pressing F8 at startup. In theory, the Windows 7 Explorer has stopped working error should not appear, otherwise you will have to run the sfc agent.

Windows Explorer has stopped working, faulty codecs

The actual question is, the explorer program has stopped working, how to fix it, because codecs are an invisible part of applications? We note right away that most often the problem is in video codecs, thanks to them a thumbnail of the video file is formed and their absence causes a failure. In some cases, other applications provoke an error.

To diagnose whether the problem is in the codecs or not, you should disable the display of thumbnails. You can do it like this:

Go to the Control Panel, with this problem it should open;
Select the "Folder Options" tile;

In the "View" tab, deselect the "Show file icons on thumbnails" option.

The type of problem will immediately become obvious, if, nevertheless, the codecs are faulty, then they should simply be reinstalled, since there are a lot of them on the Internet.

Broken conductor integrity

If the OS has been virus attack or other damage, it may show changes in the operation of system files. Not necessarily the problem is in the conductor, although there is not much difference. You should just run a special sfc scan.

Press Win + R and type cmd;
Paste sfc /scannow into the console;

Only the administrator has the rights to execute the procedure.

After checking and eliminating the error in this way, it is still necessary to destroy viruses, they lend themselves well to processing with the help of antiviruses.

Service health diagnostics

Many applications have their own services that sometimes fail. It is necessary to turn off all third-party elements in turn, and then, inevitably, there will be a problematic application. For this you need:

Win + R and type msconfig;
Go to the "Services" tab;
From the bottom, select the item "Do not display system services";

You should not disable, at least not primarily, driver services, everything else can be deactivated.

When the root of the problem is determined, you should update the drivers for the application or completely stop using it.

Video adapter driver

The cause of multiple problems, especially those related to the video component, is the video driver. It consists of complex mechanisms, is frequently updated, there are a huge number of adapters and types of drivers - all this causes the risk of failures in the application.

You just need to update the driver, for this:

Start and RMB on "Computer";
Then select "Properties";
Now open "Device Manager";

In the "Video adapters" section, select the item with a discrete card;
Double click and go to the "Driver" tab;
Now select "Update".

An alternative is to use GUI from the driver manufacturer, but it does not always work correctly.

Using one of the proposed approaches, with a high degree of probability, it will be possible to eliminate the error and return the correct processing of the conductor. Quite often, the malfunction is in minor programs, and much less often the cause is in system failures.

If you still have questions on the topic "Fixing the error" Explorer has stopped working "", you can ask them in the comments

if(function_exists("the_ratings")) ( the_ratings(); ) ?>

This is file manager, as well as the easiest way to access information on your hard drive. How to get rid of Explorer restart? This is a question you have probably asked yourself, too. The problem is not isolated, and it can be solved with skill and knowledge. But there are several obstacles on the way to a solution.

There can be several reasons for the Explorer overload.

Explorer is almost the only way to navigate through file system new computer. Therefore, if a PC is barely bought, meeting one will get a lot of unnecessary difficulties. Since it is not possible to work normally without Explorer. Another thing is if a program similar to Total Commander. But a novice user is unlikely to need it.
The explorer starts to reboot for a reason. Be prepared for the fact that, having barely installed the OS on your computer, you will have to reinstall it. After all, such behavior can be the result of a conflict in software at a fairly deep level.
Problems with Explorer are always insanely annoying for the user. Not to solve them and work normally further is simply unrealistic. Therefore, having understood, the user literally breathes new life into his computer.

Why does File Explorer keep restarting?

There are several main reasons for this:

DLL - libraries contain problems.
The drivers are not compatible with the system configuration.
The computer is infected with a virus.
An application is installed in the system that blocks the operation of one or more of its components.

If Windows 10 File Explorer keeps restarting, the first three causes are less likely. And here's why - this OS automatically loads up-to-date and serviceable hardware drivers. Even if all the drivers are not installed properly, nothing prevents you from downloading them from the manufacturer's website. But in the case of old equipment, this may not be possible.

At the same time, "Ten" contains effective means fighting viruses out of the box. These can include Microsoft Security Essentials, a program that previously came with Windows only as an option. It turns out that the fourth cause of failures for 10 is more relevant than all the others.

What to do in this case?

If you think that the application is to blame, remember - perhaps some program reacted incorrectly to actions or crashed where they should not be? If so, it's best to remove it immediately. After that, try working with Explorer again. Problem solved? If yes, great. And if not, it is possible that a completely different software became the cause of the problem. Trying to understand why the explorer constantly restarts, you will sooner or later get to the truth. And this article will help you understand the reason as early as possible.

The root of the problem

As you know, in order to understand the problem in some structure, it is necessary to consider its constituent parts. Need to start with simple testing. The first question is - is this problem only yours? To get an answer, try to reproduce the failure in a different user account. To do this, simply create an account and launch File Explorer.

After that, if File Explorer restarts again, move on to other options. If the problem has disappeared, try making the new account your primary one. It's easy, just transfer the files in the named folder (on drive C) to new folder. Or, Windows itself will prompt you to keep the old files on the disk when you delete the old user. After that, you can safely delete the old, "broken" account.

It may be that Windows 10 Explorer on a newly purchased computer or laptop is constantly restarting. On most laptop models, there is a way to reset to factory settings. Search your system for an application called System Recovery. If it is, it will be much easier to sort out the problem. Just use it and follow all the instructions provided.

IMPORTANT. If you have Asus laptop, try updating Asus WebStorage firmware. If it doesn't work, feel free to delete it.

The cause of the problem is a virus

Are you sure that virus software is to blame? Windows 10 Explorer keeps restarting for several reasons. And you can't discount this one. There may be several cases here:

The virus "replaced" some elements of the Explorer.
The virus has modified the Explorer by changing the way it starts or by embedding its own parameters into it.

It is worth considering that a virus (adware, malware, spyware) is also a program. Therefore, everything that is written above about other methods of “struggle” is relevant for him.

What else can you try?

Is the issue still not resolved? Well, there is another way to consider. This is the so-called pure Windows download. That is, a launch method that does not include any minor system component. Does Windows 7 Explorer keep restarting? Then this would be a good option. In the case of the "ten", it takes a little effort to start this mode. Try to find it in your system - at the same time you will discover a lot of new things.

If there are no problems with Clean Boot, the whole problem definitely lies in one of the installed applications. In fact, in order to run such a bootloader configuration, you will have to disable all startup items. You can do this with CCleaner help, or similar programs.

What to do if you are lazy

The forums are filled with different questions.

Mouse not working, please help me.
File Explorer restarts, what to do with Windows 7?
I have a problem with motherboard. What is the best replacement?
And many others.

It is suggested that you do the same.

Download the ProcDump utility on your PC and install it in the root folder of drive C.
Run the utility.
Reproduce the problem - make it manifest itself.
Put the error file from the utility folder on a popular file exchanger (for example, RGhost).
Place a link to a specialized forum on computer technology.

Almost all possible ways to fix the problem are given. It is very good if the first of them will save you from annoying problems. After reading this article, your problem with File Explorer restarting is solved! Leave your solution in the comments. What helped you in the fight against the problem?

We live in an era of high technology, in which the computer is no longer considered a luxury item. Nowadays, global computerization is taking place and today the PC is present not only in every home, but almost all business sectors and manufacturing enterprises have switched to automated production processes controlled by computers.

This greatly simplified human labor. However, modern software far from perfect, and therefore various problems and errors may occur in the process of working at a computer. One of these is an error in the Explorer program, in which the utility constantly restarts. It would seem, at first glance, a trifling situation makes working at a computer impossible.

Windows Explorer - Punishment or Signal?

Let's imagine for a moment such an ordinary situation. You sit down to work at a computer or just play some popular shooter, launch a program or document, and instead of opening it, it crashes operating system and the system message "Explorer is restarting" appears in front of you.

There is nothing to worry about if Windows resumes normal operation after a restart, but what if this situation repeats itself three, four or more times? In this case, most users, especially beginners, curse Microsoft, which released an unreliable product, and are thinking about reinstalling the operating system. And this is not surprising, because constant restarts take not only a lot of precious time, but also nerves. Therefore, we can say with confidence that the failure of the Explorer program is one of the most unpleasant problems of our time.

The main thing is to understand the cause of the error

To understand how the program works, you need to understand how its algorithm works. Therefore, if in the process of working at the computer there is a constant restart of the "Explorer", the program itself can indicate the reason for this. Therefore, do not rush to once again close the window with the system message, but instead carefully read it. Its text may contain an error code indicating possible reasons failure.

Knowing this code, in the service Windows support or on the Internet you can read what it is and what are the reasons behind its occurrence.
In addition, possible reasons for restarting the program may also be contained in the system message itself. Therefore, in order to cope with the problem, it is necessary to know the causes of its occurrence, and having such information, it will be possible to begin to solve it.

What can cause the constant restarts of the "Explorer"?

There can be many reasons for program failures leading to its restart: The main ones include:

- Failure in the system registry or DLL;
- Incompatible software that loads the work of the "Explorer" with unnecessary processes, leading to a restart of the program;
- Inappropriate driver;
- Malicious software.

As you can see from the above, none of the reasons for the failure of the "Explorer" is not related to problems in the operating system. Therefore, there is no particular reason to think about reinstalling Windows, but you can try to deal with the problem in other ways.

The first three reasons on the list are the result of user activity, since incompatible software is at the heart of the constant reboots of Windows Explorer. It is worth noting that in this case, the probability of a computer being infected with a virus is negligible, although this should not be completely ruled out either.

Therefore, you need to try to remember which device drivers you have recently updated, as well as which programs you have installed. If there really were any, then in most cases, a simple uninstallation of this program helps to get rid of the restart of Explorer.

Divide and rule

The failure of the program is in no way related to the hardware of the computer, so climb inside system block Or you don't need a laptop. However, you need to check the performance of the operating system and Explorer under other accounts. If there are none, then they can be easily created in the user and account management section located in the Windows Control Panel.

If Explorer constantly restarts, then the problem is more global than it might seem at first glance. However, if the problem applies exclusively to your account, then in this case there is nothing to worry about and all that is needed is to delete the current account and create a new one. In this case, the problem will disappear forever.

Alternatives

If all your efforts have not borne fruit and Explorer continues to restart, then the problem should be sought in incompatible software or inoperable drivers. In this case, you can get rid of constant failures only by uninstalling damaged programs. This is the only way to return your operating system to normal operation.

Troubleshooting through Safe Mode

If you fix the problem in normal mode Windows work fails due to constant restarts of the Explorer program, then in this case it is necessary to restart the operating system in Safe Mode, which loads only the main components and drivers necessary to start the OS. All other programs will not load. Thus, you get the opportunity to test the operation of the program in safe mode. If no restarts occur during operation, then the utility you installed is the cause of the failures and you need to continue searching for a specific program that conflicts with Explorers.

However, the situation will worsen significantly if, and in a safe Windows mode File Explorer reboots will continue. In this case, most likely, the Windows system kernel is damaged and it may need to be repaired or even reinstalling Windows.

Work without drivers

Another way to troubleshoot is to download Windows without checking. digital signature drivers. If, after loading the OS in this mode, "Explorer" works stably, then its constant restarts were caused by an incompatible driver for one of the devices. It is worth noting that, most likely, this driver will not be digitally signed, which greatly narrows the search area. As soon as it is found, it should be removed or try to upgrade to a suitable version.

We clean the system

If the above methods did not bring results and the "Explorer" continues to live its own life, then in this case it is necessary to clean up Windows startup. Optimal solution- This complete removal everything that is in autoload. In this case, the operating system will only load system files and device drivers, and third-party software will be inactive. If after that the “Program” explorer starts working normally, then the reason for its failures lies in one of the programs previously placed in startup.

Operating system rollback

If you still could not figure out the reason for the constant reboot of the Explorer program, then do not despair. You can perform a system restore and roll back Windows to the latest stable checkpoint. This is one of the most effective methods guaranteeing 100% results. At the same time, it is very convenient also because all the information stored on system drive computer, during the recovery process is saved.

Extreme measures

If you have read our article up to this point, then the problem with Explorer has not been resolved and you are on the verge of despair. However, there is one more option - complete reinstallation all Windows components. In this case, all programs and drivers you have installed, including conflicting ones, must be removed, and then gradually installed one utility at a time, while observing the behavior of Explorer. Compatibility of each installed program must be checked during operation over a certain time interval. If, after installing the next utility, “Explorer” again began to crash, then you were finally able to find a malicious program.

If you do not have such a margin of time at your disposal and you need a working operating system right now, then in this case there is only one option left - this is reinstalling Windows. However, before doing this, do not forget to first copy the entire important information on the external drive otherwise you risk losing it forever.

What to do if the problem is a virus?

As we said above, the restart of File Explorer can also be caused by malware. There are two ways to detect a virus: by installing antivirus program or with the help manual cleaning system registry, however, for its implementation, it is necessary to possess certain knowledge in the field of the operating room Windows systems, therefore, beginners are not recommended to perform any actions with the registry, since even a minor change can lead to Windows failure.

Finally, it should be noted that the restart of the "Explorer" is a very serious problem, which can take a very long time to resolve, so you will need a lot of patience.

Permanent restart Windows Explorer- one of the most annoying computer problems. First of all, this problem does not give an adequate opportunity to work at the computer. Secondly, the solution of this problem is a rather complicated process. And thirdly, it's wildly annoying. But if you happen to run into a problem when Explorer constantly restarts from several simple actions please be patient. To be honest, I don’t know an unambiguous solution to this problem, because something that helped once did not necessarily help another time. In the article I will list all the ways I know to solve this problem.

Reason for constantly restarting File Explorer

Usually, in order to somehow justify their actions, Explorer immediately after the restart shows a window that describes the problem or error that caused the restart. For starters, you can get an explanation from Windows as to what the problem is. But the description of the error code does not always accurately explain the cause of the problem. But it's still worth starting with. In addition, you can type the error code into a search engine and hope to find an adequate explanation. Also, in this window, in addition to the error code, there is a monosyllabic sentence describing the error in human language. Use it all.

So, it is important that you try to understand what is the reason that the Explorer program is constantly restarting. Understanding the cause is half the solution to the problem. I'm not asking you to thoroughly understand the reason, I'm asking you to mark in your head that "perhaps because of this, the explorer is restarting."

Top Reasons for Constantly Restarting File Explorer

DLL error.
Incompatible application.
Incompatible driver.
Virus.

As you can see, the first three reasons indicate that the failure was due to an incorrectly installed or corrupted application or driver. And only in rare cases is it the work of the virus. Therefore, you should remember what software changes were made recently, after which the Explorer was constantly turning off and on. If, after reading these paragraphs, you came to the conclusion that any application interferes with the normal operation of the system, then. The program can always be returned to its place, installed correctly, or by finding a worthy and most importantly workable replacement.

Problem localization

Finding a problem in the entire operating system is much more difficult than looking for a problem in only some part of it. Therefore, we will try to find out whether the error is a problem of the entire system, or only this user. All that needs to be done is to test the operation of the computer under a different account. If there is no other account, create it.

The result of such testing should be an understanding of whether the problem is global or local. If the problem is not detected under another account, then congratulations (this is already a small victory), the problem is only in your account. If not, then the problem is global, which is not very good.

If the problem is found in only one account, then you can quite simply get rid of it if you start working under a different account and delete the old one. Believe me, this is the most easy way problem solving.

Explorer constantly restarts, fix the situation

If any application or device driver is causing the crash, then you need to get rid of the non-working software so that the system smells good again. For these purposes, I will recommend a few possible ways problem solving:

. In this boot mode, only the main software that is necessary for the operation of the system is launched. No software or non-essential hardware drivers will be launched. You will see a clean operating system. This mode will not point the finger at the cause of the failure, but if Explorer works flawlessly in this mode, it will confirm that the software is the cause of the failure. If Explorer does not work in safe mode, then the problem is in the main core of the system. In this case, either points 4, 5 or 6 can help you, or hope that these are tricks of viruses.

Loading the operating system without verifying driver signatures. In this mode, the operating system does not check for driver signatures. If the Explorer will work adequately and will not constantly restart in this mode, then we have a problem in the driver. And this driver is not signed. And this already simplifies the task. You can find it by reading the following article. Having calculated the culprit, delete both it and the application that brought it with you.

. What is a clean boot OS? A "clean" boot of the OS refers to a clean autoload, that is, an autoload in which there is nothing. In other words, you are loading the operating system and not loading any application. This download must be done after step 1 if that download resulted in confirmation that the problem is in the software. If the problem does not appear during a “clean” boot, then the reason lies in one of the applications that is registered in startup. To run a "clean" boot, simply clear autoload wherever it exists. Help - in which everything is described possible methods autoload. To identify the culprit of the constant restart of Windows Explorer, activate all programs from startup one by one.

. This item is especially relevant if at the beginning of the article you recalled a possible cause of the failure, in the form of an incorrect installed application or driver. In this case, you can restore the system to the time the problem occurred. And in general, for beginners, I recommend starting from this point. Let me remind you that given recovery restores the system to a previous state, but does not affect documents. That is, documents created during this period will not be deleted, but deleted files will not be restored. To, you need to read another article.

System recovery using a boot disk. Having created, you can use the built-in utilities for system recovery. The process will be similar to the process

Reinstalling the operating system. Extreme option. Use when the reason lies not in the installed software, but in the system core.

Is File Explorer constantly restarting due to a virus?

Restarting Explorer can be caused by a virus in several ways:

A virus is the same software. That is, everything that is written above is true for him. If the solution to a problem caused by software is to uninstall it, then you need to special case - .
The virus somehow modified Explorer itself.
The virus changed the usual loading of Explorer to another virus shell.

I will say right away that I do not recognize the last two points as really possible reasons, because it requires really serious skills. And if a hacker is capable of this, then the constant restart of Windows Explorer is more of an accidental misunderstanding in the tricks of his virus than a purposeful action. And especially the crazy third point: why write a whole shell for the sake of a virus? However, solving this problem is not an easy task. And when all else fails, even crazy ideas seem quite adequate. So let's continue:

C:\Windows\System32\explorer.exe

The official location of Windows Explorer. Check him out, see how he is.

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon

Way in Windows Registry and the name of the parameter whose value should be explorer.exe. This parameter specifies that Windows Explorer should be the shell. If something is changed here, then you need to correct this parameter.

A similar setting that changes shell loading for an individual user is in the hive HKEY_CURRENT_USER. I don’t remember the exact location of the parameter, so google it and act similarly to the second point. (If you find the location of the parameter, please share in the comments).
Well, check your computer for viruses. Best to use boot disks with antiviruses such as Dr Web Live CD.
