Avast does not fully scan. Starting scanning when downloading in Avast Antivirus

To manage these parameters, uses the following section:
Scan Scan to Viruses Scan When Downloading Settings ...

Scanning when loading Allows Avast to detect and delete viruses before starting operating system.

Scan area

Default scanned hard drives. You can choose additional Areas for scanning.

Sensitivity of heuristic analysis - Heuristic analysis allows Avast to detect even unknown viruses by analyzing the file code. You can adjust the sensitivity of the heuristic analysis by clicking the corresponding orange stripes. In addition, heuristic analysis can be completely disabled. Increased sensitivity also increases the likelihood of false response.

Search potentially unwanted programs (PNP) - PNP is applications that are downloaded with other programs and, as a rule, perform undesirable actions.

Unpack archive files - Avast scans the contents of archives, such as ZIP, RAR and other compressed files.

When a threat is detected ...

You can choose actionswhich will be automatically performed during scanning.

  • Fix automatically - Performing a sequence of actions (to top file, if it is impossible, put it in quarantine; if it is also impossible, delete the file).
  • Move to quarantine - Move threat to quarantine, which will prevent damage to your system.
  • Treat - Deleting only a malicious code inserted into a file that would otherwise be safe. If the file is completely malicious, this action is impossible.
  • Ask - Avast will ask what to do with each detected threat.
  • Delete - permanent deleting file from a computer.
  • No action - Actions during scanning are not performed; The threat is indicated in the list of scan results, and the user can decide what should be taken later.

If you suspect that your PC contains malicious software, you can schedule Scanning when loading in a programme Avast Antivirus.which will start when the computer is then loaded. This feature allows you to check the PC for all known types of malware and delete threats before launching the operating system and other services. Scanning during download increases the chances to detect and remove malware before it gets the opportunity to act.

Scanning when loading - This is an enhanced function designed to test the system for threats. Its execution usually takes some time. It is designed to launch as needed, and not on regular use.

Planning and start scanning when loading

To schedule and run Scanning when loading in a programme Avast Antivirus.

Usually scanning takes a few minutes, but its duration depends on the speed of the system and the number of files that must be checked. After executing or skipping scan, the boot of Windows will continue.

To skip scanning, press the key. ESC on keyboard.

Hello, dear readers of this blog :) I continue my series of articles on the protection of a computer from of different types Threats, and in this article I will tell you about the protection of your system from viruses with the help of free Antivirus Avast! FREE.

The system should always be maintained in good condition. Imagine that you earn on the Internet. And on the hard disk of the computer, important data is stored for this earnings. It is very important every minute of time you pay for earnings. And one day, due to the fact that you do not comply with elementary safety recommendations, your system is infected and becomes inoperable.

You will spend a lot of time to reinstall the system or restore it efficiency. And it happens that important data will be destroyed or worse than Stolen by some virus spy. With all this, you stop at the time of your earnings on the Internet and threaten the safety of important data relating to this case. All this is just because, for example, anti-virus protection was not installed at all, or the antivirus base was obsolete or the operating system itself was not updated.

It would also be much easier to restore if they were done regularly backups. Well, this is so, a slight digression from the main topic of the article to attract all readers (especially newcomers in computer literacy) comply with at least minimal recommendations on the security of your computer :)

Go to the full consideration of the free and very good alternative to Kaspersky - Avast Anti-Virus! FREE. Antivirus is completely free for non-commercial use and includes a large number of Different protection components that block a variety of threats. In this case, the antivirus does not much loading the system, has a very flexible setting and many additional addicts :)

We now turn to the consideration of the Avast Anti-Virus Installation process.

Installing Antivirus Avast! Free.

First of all, before proceeding with the installation of the anti-virus product (any), it is necessary to remove the already installed on this moment in your system. Two simultaneously working antivirus (it is precisely complete complex antivirus. There are also separate - antispiods) - can conflict with each other and lead to system failures. Be sure to remove your current antivirus Product Before installing a new one.

So, start the installation:

    Antivirus is more convenient to download everything from the official site, because so you always download the latest version. Go to the site:

    avast.

    On the site go to the menu at the top "for the house", after which I choose the item "Avast! Free Antivirus.

    Scroll through the page about down to the middle until you see a comparison of the 3 versions of the antivirus and the "Download" buttons. We are interested in the free version of "Main Avast! Free Antivirus "and click on the" Download "button below it:

    I would like to immediately answer the possible question: "But in the table comparison, it is clear that the free version is defective and there are no many functions in it. Why then put such a version? ".

    Now we are talking about protection against viruses, spies, trojans and similar threats and so let's consider what is missing in this free version according to the table:

    That's all will be absent in the free version. Now we'll deal with what.

    SafeZone - Does not be protected from viruses, and it rather refers to the additional component. To protect payments and everything else is enough to have reliable antivirus + firewall + to observe other recommended security measures when working on a computer. And for reliable storage of passwords, business cards and similar to apply a special password manager, which are full of free. I told about one of them here in this article.

    Automatic firewall. The one that is embedded in Avast does not deserve the necessary trust, compared to the popularity and has excellent protection - Comodo Firewall. I recommend it separately, and I promised to write this article :)

    Protection against spam. Again, for such protection, it is enough to have everything that I wrote above, and it makes no sense to buy a paid version of the antivirus for this feature. You can use, as a last resort, separately installed anti-spammer.

    Software Updater.. Each installed program On the computer, it has its own update features, so this tool is completely useless. And, especially since free version still embedded this tool, but the difference from paid only is that it needs to be launched manually :) and in the paid version of the update third-party programs Go automatically. I think it is absolutely not fundamentally for us.

    Accessanywhere.. To obtain a full-fledged remote access, it is more convenient to use a separate free program - TeamViewer, which has everything required functions And even more. If you are interested in readers, relative to this program, its work and configuration, I will write a separate article on this topic :)

    Schroeder Data. Allows irrevocably (without the possibility of recovery) to delete data using special algorithms. Again, the program designed for this can be installed separately if necessary.

    So we went through all additional tools that are available only in paid version Antivirus Avast and, I think, managed to explain why it is absolutely no sense to pay for this :)

    Opens new pageand immediately should start automatic download Anti-Virus Installer on your computer. If the download does not start automatically (it depends on the browser and its settings), then start the download manually by clicking on the link "Click here":

    You will start downloading a file to your computer in your selected folder, or automatically in the folder that is specified in your browser settings.

    To start the installation, we start the downloaded file. "Avast_free_antivirus_setup_online.exe".

    The first AVAST installer window will start. I recommend to remove the checkboxes "Yes, install Google Chrome. like my default browser "and" Yes, set the Google toolbar for Internet Explorer." All this, if necessary, you put separately by downloading free from the Internet.

    As for choosing the type of installation, I recommend choosing "selective installation". This allows you to more finely adjust the installation of the antivirus. Click on this button:

    In the next window, the installer is offered to select a folder (path) to install an antivirus. I always leave the default path and recommend doing it also when installing any programs. Click the "Continue" button:

    At the next stage of the installation, it is proposed to choose independently which antivirus protection components, additional tools and languages \u200b\u200bwill be installed. Protection Components (Screens) Install All Mandatory! This is the main component in defense. The tools recommend to leave the same as default (see the image below), but it's better to turn off the "Gadget Avast!" Instrument, which does not play an important role, but will interfere and load the system. Languages \u200b\u200bchoose at your own discretion, and I left only Russian.

    Click the "Continue" button after all set up at this stage.

    In the next window, we once again notify how we set up during installation. Click the "Continue" button:

    At the next step, it is necessary to simply press the "Continue" button again and thus we accept the terms of the license agreement:

    Installation process will start. At this stage, no action will be needed from us:

    After the installation is completed, click the "Finish" button and quickly scanning the system for viruses will be launched.

    You can wait until the scan is completed, and you can interrupt it by clicking the "Stop" button. This is at your discretion:

On this, all the steps to install Avast Anti-Virus are completed, and it is ready for work. But I talked about what I would tell in the articles how to configure antiviruses to maximize protection. Therefore, now go to the discern of antivirus settings.

Setting up Avast Anti-Virus! Free for maximum protection

If a working window Anti-virus has not opened immediately after it is installed and quick scan, most likely you closed it. You can open it from the tray (system area with icons where system hours are located). To do this, click 2 times the left mouse button on the Avast icon:

So, to begin with, we activate our free version:


Now go directly to the settings:

    In the Avast window, open the "Settings" tab in the list on the left.

    A new window will open, where there will be many more tabs, for each of which we will go. The "General" tab will immediately be opened. Consider the settings on this tab.

    I recommend to leave the "Participation in the Avast community" function included. Some Avast use data will be transmitted to servers, but you will receive statistical information about the content and ranking of sites and other information. Since we are officially free, we are not afraid of all sorts of blocking and other related to the fact that the program will send data to antivirus servers :)

    Having dropped on the page just below we will see the section "Password". Here you can set a password to protect various program functions. It can be done and even needed by 2nd reasons. The 1st is the protection of the settings of the antivirus and its work if the computer uses another person besides you. And the 2nd reason, which in my opinion it is even more important than the first - password protection of the main functions of the program so that some types of viruses themselves can not change anything and disable. Believe me, this in practice is found.

    So, put a tick "Protect Avast! Password "and below 2 times specify some simple password. Below are another additional section "Protected Areas". Here we offer to choose: when accessing which areas of the program will be requested by the password. Here at your discretion, and depends on which of which of the 2 reasons you installed the password or on both :)

    If you are protected by password only from special smart viruses, I recommend leaving the checkboxes as in the image above. That is, the password will be requested when accessing the basic settings of the program, when you enable / disable protection and when working with threats that are on quarantine.

    Go down even lower and see the "Service" section. There are settings for storing reports, antivirus and quarantine magazines. It is all optimal here, but if you want to extend the life of some reports, you can specify large quantity days, as well as specify another quarantine volume. I leave everything, because there is:

    If you go down even lower, we will see the last function on this page - " Backup settings. " But it makes sense to apply it when all the settings are done, so we will return here later.

    With the first tab, they figured out and now go to the settings of the next tab "Active Protection". In the window, check that all 3 shields of protection are included, and then click on the button with the image of the gear opposite the "screen file System"To go to its settings:

    And here we will again expect a lot of tabs :)

    1. At the moment, the very first tab is open - "scanning when performing". In the window on the right we simply check that all functions are active (all 3 ticks stood):

      Go to the next tab "Scan when opening". For maximum protection, we turn on two functions: "Scan Documents when opening" and "Scan All Files":

      The inclusion of the last function can affect the speed of the computer if it is weak. The official site does not indicate system requirements Avast (at least I wanted to find to add to this article and did not find it), but according to my own tests on different machines I can say for sure that these requirements are far from high and even "weak" today computers will cope.

      You can install "Scan with Custom Extensions" in case you did not turn on the "Scan All Files" function. Then in a special window you can specify the extensions of the files that the antivirus will scan.

      Next tab "Scan during recording". Here I recommend putting 4 ticks, as indicated in the image below. The "Scan Files with Custom Extensions" item can again be enabled if for some reason did not turn on "scan all files".

      The function "Do not scan files on remote shared resources" is enabled, because the scanning of folders and files on other PCs is no longer assigned to us and at the same time will heavily lower the performance if remote folders will be much, and there will often be different changes.

      Since the "Do not scan files on removable media" function is turned off, then when inserting flash drives and other media, it will be possible to immediately scan files and it is very important! Just because on removable media very often there are many diverse viruses, if this media connects to other computers. This is how to configure just in the next tab.

      Tab "Scan When Connection". We check that both ticks stood here as in the image below. The first function will allow you to check the connected media immediately to prevent the system infection, if the carrier itself is infected.

      The second function scans the floppy disks. Although they can still be said nowhere apply, they still do not need to turn off this function.

      Go to the "Exceptions" tab. Here we can set files, folders and extensions that will not scan antivirus. I always remove all the default exception files because specified files still can be malicious codeAnd they can be subject to change. Therefore, it is better to remove all the checkboxes in this window, and add only those files and folders if necessary, which antivirus is mistaken, and you know exactly that these threats do not represent. Such files, for example, often include various activators for programs.

      The "Advanced" tab. In the settings window, I recommend turning off the "Do not scan verified system DLL files", Which is enabled by default, as system files may become infect and periodically scan them.

      Function "Use constant caching". Disconnect, otherwise the antivirus will not scan the second time files (even after reboot), which have already been scanned and turned out to be "clean."

      Tick \u200b\u200b"Use short-term caching" and "Optimize scanning when copying files" leave.

      Go to a very important tab - "Actions". Here you can configure the behavior of the antivirus when threats and suspicious files are detected.

      The best option is to install in all 3 subsections (virus, PNP, SUSP. File) values \u200b\u200bof Avast action as it is below:

      Those. If a virus is detected, a suspicious file or a potentially unwanted program (PNP), the antivirus will first ask you what to do with a detected object, and you yourself can choose an action. If for some reason he could not give the window with a choice of action, then the antivirus will try to choose the most correct action above the object and if it did not work, it will definitely send a file to quarantine. In fact, the 1st action (asking) can be said that it will be issued in 100% of cases, and the rest we ask only for the safety net.

      Having exhibit actions in the "Virus" tab, exhibiting the same thing in the "PNP" and "Susp. File".

      Below in the "Parameters" section, we leave both ticks included.

      In the "Processing of infected archives" parameter, the second option is best to include - "Trying to extract only an archived file; If it does not work, delete the entire archive. " In this case, the infected archive will be deleted entirely if you confirm this action.

      Now we go to the "Archives" tab. This section Allows you to note the formats of archives that Avast will open when checking for viruses.

      As I show how to configure the antivirus to maximize protection, then we just celebrate the checkbox "All Archives":

      The penultimate tab "Sensitivity". She is also responsible for antivirus protection. We put the sensitivity to the level "high", i.e. - We note all the strips (see image below). All ticks in this window turn on.

      On the latest tab "Report file" is nothing particularly important. There are settings for reports that are created after scanning. The options specified here by default are quite optimal.

      On this file system screen settings (this is a scan that is performed in real time) is completed. Click the "OK" button in this window.

    As a result, we will return to the "Active Protection" tab and now proceed to setting up the next screen - "Mail screen". Open the setting by clicking on the same button in the form of the gear:


  1. We left to configure the latest screen - "Web screen". Run it setting it:


  2. We move to the "Antivirus" tab and begin to consider the list of settings here.

    In the "reputation service" subsections, Deeppscreen, "reinforced mode" are already installed by default the necessary parameters And here it is best to leave everything unchanged. DeepScreen feature allows you to learn about content unknown File Even before it starts and it improves safety. The enhanced mode is not necessary, since we turn out the settings for maximum protection, and this feature Recommended for inexperienced users and you will not be able to flexibly.

    Below on the same tab will be the "Exceptions" subsection, in which you can add general exceptions immediately for all the screens discussed above. Why do you need exceptions, I already painted above and add them only in acute need.

    Even below will be a "warnings" subsection, which will allow you to send notifications to anyone by mail, if the computer has been detected. The function never used and I can hardly and for some reason I am sure that you too :) Therefore, you can not prescribe any addresses.

    Well, before him - subsection "Special types of scanning". There are a little delayed. "Scan the screensaver" we will not touch, since this default function is optimally configured. This scan is made at a time when the screen saver on the computer is turned on and is performed unnoticed by the user. But the second scan type is "Scanning in Explorer" better set up. Click the "Settings" button next to the corresponding item:

    And again we see a number of tabs :)

    But I recommend walking on them, because the scanning in the conductor is not rarely very convenient. It allows you to check any folder or file by right-clicking on it and choosing the "Scan" item. This type of scanning we will now configure.


  3. Now continue checking the settings on the previous window. We go to the tab " Appearance" For the security of the computer, the settings are not responding here, but it can affect performance and amenities :) We will go on settings from this tab.

    I recommend first to turn off the "Animation of the icon when scanning". Animation in any case requires at least not significant, but more system resources despite the fact that there is no sense in this option. Also, I always turn off the sounds, whatever the antivirus does not use. Here at the discretion of everyone, but it is more convenient for me to simply receive text notifications than hearing and distracted by sound alerts.

    Go down below the settings in the same tab and see the "Monitoring of Activity" subsection. This monitoring is responsible for the output of the protection status data, and the checkboxes below can be noted which components and parameters to consider when the output of this data is output. If one of the selected parameters / components is not in order, for example, disabled, then the monitoring will display a warning that protection is not perfect. For example, viral bases are strongly complained, and it will give a warning about the status of protection, since I have the item "Version of Definitions of Viruses".

    By default, everything is right here, so it's better to leave everything:

    Even below, there is a subsection "pop-up messages", which is responsible for the duration of windows with notifications. Here I do not set up anything, but if you wish, you can change the duration.

    Even below - the "Greeting" subsection. Tick \u200b\u200bhere is absolutely not needed and if it stands, you feel free to remove it.

    In the subsection "Scan Results" also not needed. After scanning, the results will be so open in the event that there are some important moments, for example, a threat was detected.

    And finally, at the very bottom of this tab, in the last subsection of the "Community Functions", the default function "Show recommendations of Avast!" Is enabled. It is better to leave it enabled that additional options are available.

    Below in the screenshot shows the last 3 subsections with the desired settings:

    Now go to the next update tab. Here we can manually update the viral database by clicking the "Update" button under the "virus definitions" heading.

    Definitions of viruses are updated automatically. But when the new version of the antivirus is released, it will not automatically update. Therefore, once a week 2, look at this section and press the Update button under the program heading. If a a new version It turned out, it will boot and install.

    Here I recommend putting a tick "My computer is constantly connected to the Internet." Also here you can change the frequency of checking the updates of the viral base. By default - every 240 minutes, and I consider this normal interval and do not change this value. In the proxy settings, leave the "Direct connection (without proxy)" item. Only if you use a proxy server to access the Internet, then here you specify the data of this server by including the corresponding function.

    Next tab - "Registration". There is nothing important for us and just show to familiarize yourself :) Here you can view whether your activated is activated free license, as well as the number of days before it is completed. After graduation, you can get a new license again.

    Also on this page you can activate the paid version by clicking on the appropriate link if you suddenly purchased it.

    Next, we go to the tab "Tools". Here we will see additional free tools that do not belong to the most antivirus protection. These functions are useless and more convenient to use full separate programsdesigned each for their needs. Our task is to just turn off both of these tools :) click the "Settings" button next to the "Software Updater" tool:

    In a new window, simply remove the tick next to the "Software Updater" item, and then click "OK", thereby returning to the previous window.

    This tool can check the new versions of the entire installed on the computer. software. But it only cleaner resources despite the fact that each installed program is so can check for yourself updates.

    Now turn off the use of "Grimefighter":

    In a new window, we remove the only tick on the top of the "Always Test This Computer for Grime". After that, click "OK" and go back:

    The GRIME tool is used to clean the system from the garbage. To do this, it is best to use a separate utility, for example - CCleaner, which and the registry captures, and unnecessary files Deletes and errors will correct. By the way, if the readers will be interested in the topic of cleaning the system to increase productivity and correct errors, then I can write an article and on this topic :)

    A similar tool built into Avast is completely stupid and does not have all the functions for this.

    Finally, go to the last tab in this large settings window :) The Tab is called "Troubleshooting". Honestly, in my opinion, the developers incorrectly transferred this tab, because I do not see here unified function, which would eliminate some kind of malfunction :) Well, in fact, we will not find fault. In this tab, the most optimal and best from the point of view of the maximum protection of the antivirus are the settings that are set by default. These settings are exhibited in my screenshot below:

    By setting the settings, press the "OK" button and finally leave this largest window with the settings, and in general this is all settings! :)

Congratulations, anti-virus protection in real time is configured to the highest security! :) I agree, the settings in Avast are just a lot. But such flexibility of settings and overall protection and bring it to the best free antivirus products.

Now it's small and left to tell about the variants of manual scanning of the system and their settings.

Manual computer scan to viruses with avast antivirus! Free.

Let I mention already in the previous article (about Kaspersky Anti-Virus), but I repeat just in case, because not all readers learn each article on the blog. And it's not difficult to repeat it :)

Although antivirus and protects your computer in real time, but some kind of infection can still enter your computer by chance. And even more so, the defense, no matter how cool is inferior to a paid Kaspersky.

In this regard, it is necessary to regularly fully check the computer for viruses manually. I do it weekly. I have a productive computer, and therefore I don't even notice the full scan process. I recommend not less than once a month so as not to neglect the security of your system.

So, we begin to understand the manual scanning of the system:

In the main window of Antivirus Avast! Go to the "Scan" tab.

On the right, we will see the drop-down list with scan options, link to the settings and the start button.

Of all the scan options, we will consider only the 2 most important: "full scan" and "scanning when loading OS".

Let's start with the full scan settings:

This type of scan makes a thorough, in-depth check of your entire system, all local drives and it is I use it all the time.


To start scanning, you just need to just go to the "Scan" menu, select the "Full Scan" type and click the Start button.

This will look like running process Scan:

We still have to wait for its completion. And if for some reason you need to interrupt the scan, then you can make it simply by pressing the "Stop" button or "pause" (according to the notation).

The second scan type marked by me produces scanning before launching the operating system. Such a type of scan can be useful if for some reason the system has ever infected some incomprehensible infection, and you cannot eliminate this threat with the help of an ordinary manual full scan from the system. Then most likely the threat will be found precisely during the scan when loading the OS.

We proceed to setting up the scan during OS boot:


On this scan settings when booting OS completed :) If you press "Start" in this type Scanning, it will start when the system is then loaded. Those. Enough to click "Start" and restart the computer.

Well, all the most disassembled important settings And Avast Anti-Virus Functions! FREE.

The remaining tabs are not so important to affect them in detail. For example - "Store" - only need if you want to acquire some paid versions of antivirus. In the Tools tab, there are additional programs for the antivirus of the program, for example, previously "Software Updater", "Grimefighter" and so on. The "My Devices" tab makes sense only in an extended version of the antivirus, because it implies remote access to other computers with Avast!, This feature is not available in our free version.

Tab - "Statistics" allows you to view statistics on scanned files; What percentage of infection, which percentage is cured for different periods. But I do not use this feature :)

Well, actually everything :) Article So it turned out a huge size, but but I touched the main thing - how to set up antivirus to maximize protection :)

I will be glad to any comments :) That's all, I wish you good luck in your affairs! ;)

Avast Free Antivirus is a free antivirus program (requires free registration), which has received many awards and proven as easy to use and reliable antivirus.
