How to clean Windows 7 from viruses. How to clean your computer from viruses yourself

Find out which the best means deleting malware exist is not that difficult. By request, the Internet can easily find applications that allow you to troubleshoot computer problems associated with a virus infection.

Such software usually distributed free of charge or shareware.

Although its capabilities include quick search and guaranteed removal malicious code and annoying advertisements which well-known (and, most often, paid) antiviruses cannot always cope with.

Windows 10 built-in tool

The first way to get rid of malicious applications, which should be used by an ordinary Windows 10 user, involves running the already built-in Microsoft Malicious Software Removal Tool.

Sometimes it works automatically, but if a virus infection has already occurred, the tool is launched manually. You can find MMSRT in the System32 folder system disk located in the System32 directory. The efficiency of the application is not very high, but at least half of the problems will be solved.

The benefits of using the product include:

Russian-language interface;
intuitive control;
no need to download additional software.

Among the disadvantages of the application are long scan times and low efficiency. And you can download it not only for Windows 10, but also for the 7th and 8th versions operating system... The update, numbered KB890830, is only 52.8 MB in size.

Fast and free AdwCleaner

One of the most famous and effective programs allowing you to remove unwanted applications from a computer is AdwCleaner. The advantages of using it include work in Russian, no need for installation on a computer and constantly coming out updates that improve the quality of the system check.

In addition, after completing the scan, AdwCleaner provides the user with several recommendations on how to prevent infection with malicious code. And to run the utility, you just need to click the start scanning button, and after reviewing the results, set the settings and select the information to be deleted.

The peculiarity of the application is that during the scanning process it is sometimes necessary to restart the computer. And after the completion of the work, a report is displayed on the screen, which can be saved as a text file.

A Simple Yet Effective Junkware Removal Tool

Fig. 4. Report on the operation of the Junkware Removal Tool utility.

The utility is accompanied by the creation of a system restore point. And during the scanning process, it automatically fixes problems and removes virus programs. The check ends with the creation of a detailed report on the problems found and their solutions.

CrowdIsnpect - search for unwanted processes in the system

Malicious applications can also be detected by the processes running on the system. This is the basis of the operating principle of the CrowdInspect utility, which scans the startup list and works on this moment service. With the help of a constantly updated database of viruses and unwanted software, the program collects information about the processes and compares it with a list of potential threats.

Fig. 5. Analysis Windows processes using the CrowdInspect utility.

One of the results of the CrowdInspect system check is the display of a list network connections and IP addresses, as well as the reputation of the sites to which they belong. Although most of this information can only be dealt with by advanced users. For the rest, it is advisable to choose utilities that automatically fix problems to remove malicious code.

Shareware utility Zemana AntiMalware

In terms of the effectiveness of the fight against viruses and unwanted extensions, Zemana AntiMalware is not inferior not only to other free utilities, but even to the paid versions of some well-known antiviruses. The advantages of the program include the possibility of cloud search, an understandable Russian-language interface and system protection in real time. The paid Premium version has even more benefits.

Fig. 6. Search for malicious programs using the Zemana AntiMalware utility.

Zemana does a pretty good job of removing plugins from browsers, which often lead to pop-up advertisements. Although to start the search for extensions, the program settings will have to be changed by going to the "Advanced" section.

And the disadvantages of the utility include shareware distribution - after 15 days you will have to pay for its use. Although usually a few hours are enough for a quick scan of the computer, after which the application is removed.

HitmanPro - Maximum Efficiency When Removing Plugins

Fig. 7. Work of the HitmanPro utility.

The program effectively removes most common viruses. And when checking browsers, it finds and fixes problems with extraneous extensions. After the scan is complete, the user is prompted to review the list of detected problems. And, if any of the marked files is not dangerous, according to the user, it can be removed from the quarantine.

Spybot Search & Destroy - Increase PC Security

Fig. 8. Spybot Search & Destroy - search, elimination and prevention of problems.

Spybot is able to monitor registry changes and system information, thanks to which it not only solves problems that have already appeared, but also ensures the prevention of possible malfunctions. In addition, all changes made by the utility can be undone - sometimes this helps to avoid crashes in Windows when a useful file is deleted along with a virus.

The most powerful, but slowest Dr.Web CureIt!

The most powerful and efficient utility is Dr.Web CureIt! , the advantages of which include the possibility of free use. By downloading latest version application (the size of which exceeds 100 MB) and running it on a computer, after a few hours you can get a report on the work done, and a system that is 99.9% virus-free.

It is CureIt that recommends using the technical support of some Internet providers. The application has only one drawback - you can use it only once. A few hours after the download, the next update comes out, and the old one stops working.

The advantages of the utility include not only high level the effectiveness of the search for malware, but also the ability to download it again. After re-downloading from the manufacturer's official website, the application is again ready to detect viruses. At the same time, the databases have already been updated, and the search efficiency is increasing.

Fig. 9. Message about the need to update the Curelt utility.

Solving browser problems

In the process of removing viruses, you should also pay attention to the shortcuts of the browsers - they are often the source of the problem. The malicious code is written in the properties of the shortcut and changes the way it is launched:

sometimes when logging on to the Internet the user is not directed to home page, and to another site - most often phishing or advertising some services;
along with the launch of the browser, an external plug-in may be installed that changes search engine, home page and networking options.

You can fix the problem manually by checking the browser shortcuts. But the best way to do this is with utilities such as Shortcut Scanner. The free application checks logical and external drives for the presence of unwanted programs, identifying suspicious or broken shortcuts.

The advantage of using this tool is free distribution and work on any modern Windows systems (from XP to 10), the disadvantage is the lack of a Russian-language version.

If the unwanted plugin has already been automatically installed in the browser, you can uninstall it through the extensions menu in the settings. Otherwise, instead of going to the selected pages, the screen will display advertisements and extraneous resources.

Most often, this problem occurs for users who have already installed a significant number of extensions and do not notice 1-2 unnecessary ones. If there are practically no plugins, it is easier to notice the new one and take measures to disable it. And if you are not sure that the add-on is actually malicious, special utilities developed for specific browsers will help.

For Google chrome official developers created a utility called Cleanup Tool. It automatically checks for embedded malicious code every time you launch your browser.

If a problem is detected, the plugin is disabled along with the rest of the extensions. After that, the user can manually restore the add-ons he needs.

Fig. 11. Search for malicious code with Chrome Cleanup Tool.

For Mozilla Firefox and standard for old Windows versions Internet browser Explorer exists free app Avast Browser Cleanup.

Utility in automatic mode scans two browsers (if there are any in the system), and as a result it gives out a list of suspicious plugins. The antivirus program can be downloaded from the manufacturer's official website.

Fig. 12. Cleaning the browser from malicious code using Avast Browser Cleanup.

Similar in functionality and the same free utilities are also produced by other companies. Moreover, for different browsers and with a wide range of features. Some programs also provide effective real-time protection - however, most of them have such an option for a fee.

conclusions

Using applications that remove unwanted software does not eliminate the need to install antivirus software. Each program performs its own tasks. Antivirus utilities protect the system almost constantly, and prevent infection of system files.

And applications for eliminating problems that have already appeared are needed, mainly after the antivirus has turned out to be ineffective. Using two options at once - installed and periodically launched utilities - will provide maximum protection efficiency. Although in order for the computer to be even more secure, it is desirable:

follow the recommendations of antivirus utilities that issue warnings when entering suspicious resources;
check with antivirus files downloaded or recorded from an external medium, the origin of which is unknown (for example, downloaded not from the official website, but from an outside web page);
set in antivirus settings automatic update virus databases and run the application manually at least once a week.

Preventing viruses and other types of malicious code from infecting your computer will reduce the likelihood of problems. However, neither Curelt !, nor even a paid antivirus can provide 100% protection.

Best Malware Removal Tools
