This guide is out of date

Computer viruses poison life. They destroy files and entire partitions on disks. Slow down the system. They insidiously use the address book to send copies of themselves to our friends and colleagues. There are many antivirus programs with a rich history of development and famous names of their creators. We're looking at a popular program called avast!. Like its "colleagues", avast! can scan your computer, find and remove viruses, protect the system from infection and automatically receive anti-virus database updates via the Internet.

Installing avast!

• Click on the icon avast! below to go to the developer's website.
• Select the “Free antivirus” option and click on the “Download” button.
• Creators avast! may be redirected to another Russian site, from where the program will be downloaded faster than from abroad. For example, on softportal.ru. We find there the link(s) to download the program, download the distribution file(.exe) and save it to disk.
• Launch the installer by double clicking.
• We follow the recommendations in the chapter Installing the program.
• After installing the program, you can remove the distribution package.

The version of the program used here: 6.0

Distribution volume: 92 MB

Possibilities

You should not think that the best antiviruses must necessarily cost a lot of money. Free avast! - a powerful means of combating “computer diseases”. The modern user will appreciate protection against penetration into the computer from the Internet and blocking of suspicious attachments in emails.

The user of an antivirus program should remember two things:

• New viruses are constantly emerging. Therefore, you need to keep your anti-virus database up to date. Avast! itself, automatically downloads database updates from the network, the main thing is not to interfere with it.
• Trying to run two or more antiviruses at the same time can lead to a serious conflict and freezing of the entire system. Before installing avast!, make sure that there is no other antivirus on your computer. If there is, it is better to remove it from the system (or at least disable it) before installing avast!.

Alternative programs for GNU Linux, Mac OS and Microsoft Windows

Except avast! There are other free antivirus programs for Microsoft Windows, For example:

If your budget allows you to purchase a commercial (paid) antivirus for Microsoft Windows, this might be a good option. Commercial antiviruses often offer more complete and advanced protection.

Although operating systems GNU Linux And Mac OS are considered relatively virus-free, this danger should not be neglected. You never know when a killer virus for these operating systems will appear. In addition, you can end up (unintentionally, of course) spreading viruses, even though your own computer is not infected.

Today, alas, no free antiviral agents that could be wholeheartedly recommended for use in Linux And Mac OS. There are, however, a few worthy commercial products, for example:

Installation and registration of avast!

Before installing the program, we recommend that you stop and remove other antivirus products from the system, if any are installed on your computer. Different antiviruses can conflict with each other and lead to various troubles, including system freezes.

• Run the installation file (.exe).
• Selecting the installation language. Leave "Russian" (default) and click "Next".
• Welcome window. For security reasons, we recommend unchecking the “Participate in the avast community!” box. Click "Next".

• Avast! Recommendations. If you do not have the Google Chrome browser installed, the persistent developers of avast! They will advise you to download and install it. You do not want? Then select “No” and click “Next”.

• Installation process, the progress of which can be observed, and express scanning of the system (despite the “express”, it can last quite a long time). The Installation Complete window. You can click the "Done" button. A “branded” orange circle will appear in the lower right corner of the screen (system tray).

After installing avast! will remind you about registration.

How? Free program - and registration? Yes, this happens. Without registration you can use avast! 30 days. Registration is free, just like avast!. During the process you will need an Internet connection.

• Click on the orange avast icon! in the system tray (bottom right corner of the screen).

The main avast! window will appear, in which you will see the phrase “The program is awaiting registration, please register.”

Another colorful window with information where we are offered a paid version of the program.

Find the gray “Registration” button and click on it. Now we have the registration form:

• For reasons of privacy, we advise you to fill in only the required fields (name and e-mail address).
• Click on the “Register for a free license” button. This completes the registration procedure.

Now you can use the program without “reminders”, completely free, for a year. A year later, Avast! will ask you to re-register (also free).

Avast update!

You may ask why we started talking about updating it immediately after installing and registering the program? The fact is that updates are important for an antivirus like no other program. New viruses appear every day, and it is very important that your security system is aware of them.

Avast! automatically checks for updates. When a suitable update is detected, the program downloads and installs it. A window pops up in the lower right corner of the screen saying that the program has been updated.

Both program files and the anti-virus database are subject to regular updates (the creators of avast! call it the “virus scanning and detection module.”

If you want to update Avast! You can also do it manually.

• Click on the avast! in the lower right corner of the screen with the right mouse button.
• In the "Update" menu, select "Program" (for program files) and/or "Virus scanning and detection module".

If the updates are major, you may need to restart your computer.

If you do not have constant good access to the Internet, you can disable avast! attempts to automatically go online and download updates (although we do not recommend this).

• Click on the avast! in the lower right corner of the screen with the left mouse button. The main program window will open.
• At the top we find the menu and select “Program Settings”.

• In the left column, select "Updates".

• Both the program and the virus scanning and detection module offer three modes to choose from. Avast! It may automatically download updates, or ask you for permission, or do nothing. In the latter case, you will have to update the program and anti-virus database manually - perhaps not the worst option, just remember to do it regularly.

Finally, there is the option to download the update from the developer's website

This is useful when there is a need to update the antivirus on a computer where there is no Internet connection at all, or where its speed leaves much to be desired. The file can be downloaded where the speed is good, written to a disk or flash drive, transferred to the desired computer (with avast installed!) and run the update (this is a regular .exe file).

Avast! looks something like this if both the program and the scanning module have been updated correctly (main program window, menu "Summary" - "Current Status".

Checking your computer for viruses

Even if the presence of a virus is not felt on the computer, this does not mean that the system is free of malicious code. Many viruses do not manifest themselves until certain conditions occur. Therefore, from time to time it is useful to run a disk scan for viruses.

Let's take a look at the main program window. (It can be called up by simply left-clicking on the avast! icon in the lower right corner of the screen).

On the left are large vertical menu buttons.

• Summary. Here you can find basic information about avast components! (including how recent they are) and avast! usage statistics to scan for viruses on your computer.
• Scan your computer. Different options for scanning your computer for viruses: right now, when you boot your computer, as well as the results of previous scans.
• Real time screens. From here you can start (or, conversely, disable) protection for various processes, for example, protecting email or browsing web pages.
• Additional protection. At this point you can enable and configure the “Sandbox” (sandbox) - this is how the developers of avast! they call the special area created by the program where avast! places programs that seem suspicious so that they do not cause damage to the computer's system files. In addition, here you can enable the module for viewing the reputation of WebRep websites and block specific sites.
• Service. Updating and registering the program has already been discussed in previous chapters, and we will talk about “Quarantine” a little later. In addition, here you can see information about the avast! program itself.

Let's try to scan your computer for viruses.

In the main window of the program, in the left menu, select “Scan computer” - “Scan”.

avast! offers four possibilities.

• Express scan. Recommended as the fastest way to make sure that the main components of the system are not affected by viruses.
• Full scan. If you have the time and want to do a deep scan of all files, this option is for you.
• Scanning removable media. It is useful if you connect a flash drive to your computer, which cannot be said for certain that it is “clean”.
• Select a folder to scan. Full scan, but not the entire computer, but a separate folder. Convenient if you suspect that the virus is localized there.

For more information about each scan option, click the Learn More link.

There you can also configure scanning parameters (this option is more likely for advanced users).

To start express scanning, just click on the "Start" button.

Scanning will begin.

Upon completion of avast! will show how the scan went. If a threat is detected, the picture will look something like this:

Click on the "Show results" button

Other types of scanning are performed in the same way.

In the "Startup Scan" menu, you can enable virus scanning by clicking the "Schedule" button.

Every time you boot your computer, avast! will scan your hard drive (or drives) for viruses. Why is it important? In this case, avast! scans computer hard drives before loading most programs and even drivers of the Microsoft Windows operating system itself. Viruses do not have time to get into RAM and activate, avast! ahead of them, which allows him to do his job more efficiently. If you suspect that a virus is “mastering” your computer, one of the usual recommendations for such cases is to run avast! in Scan at Startup mode.

What to do if avast! Found an infection on your computer?

If this happened in the "Scan at Startup" mode, you will see a blue screen with text in front of your eyes (after all, the Windows GUI has not yet loaded). avast! will prompt you to delete, move, disinfect the infected file, or ignore the problem. (The latter option, however, can hardly be considered reasonable).

In other modes you will have the following choice:

• Treat. avast! will try to get rid of the malicious code in the infected file without any losses for you and the system. This doesn't always work, but it's worth a try.
• Move to quarantine. Do not delete, but isolate the infected file so that the virus cannot harm other system components (see below for more details).
• Delete. avast! simply deletes the infected file. This can be the simplest and most effective way to solve the problem - of course, if you are sure that the file is of no importance either to you or to the operating system.
• Do nothing.

A little more about quarantine. It may happen that a pest has “infiltrated” itself into one or another important file. It is not your plan to delete this file; on the contrary, it is very important, but it cannot be cured. For these cases, the authors of avast! and came up with "Quarantine". The program isolates the file from the system, preventing the virus from spreading and giving you the opportunity to think and decide what to do next. By the way, there are situations when even the best anti-virus program misfires and mistakes a completely normal file for a virus (which, from the point of view of this program, demonstrates “suspicious behavior”). Careless deletion of such an “innocent” (but important for the system) file can be fraught with trouble. And you can always extract it from “Quarantine”.

In this example, avast! After a successful scan, he localized the virus and suggested options for further action.

Select "Move to Quarantine" and click the "Apply" button. avast! executes the command, although it does not produce any results. When you close the avast! persistently offers to enable scanning when starting the computer. You can see the file in “quarantine” if you select “Maintenance” - “Quarantine” in the main program window.

A quarantined virus file looks like this:

By right-clicking, you can perform various actions on the file, for example, delete, restore “as it was” (before Avast intervened!), save in another folder on the disk, etc.

Like any decent antivirus package, avast! includes not only a scanner (which runs periodically), but also a resident (permanently located in memory) anti-virus “screen”. This helps to constantly monitor the “health” of the computer and prevent viruses from entering the system.

To be precise, avast! There are several resident program modules, which the developers called “screens”. In the main program window they are listed in the "Live Screens" menu.

By clicking on the screen name in the menu, we get more detailed information about it on the right. Each screen can be turned on or off using the Start and Stop buttons.

There are eight screens in total:

• File system screen. The main screen of avast! scans files as they open (in particular, programs at startup). In particular, it scans programs at their startup.
• Mail screen. Scans incoming (and at the same time outgoing) mail, including, of course, attachment files. Very useful if you use an email client such as Mozilla Thunderbird.
• Web screen. Internet protection when browsing websites.
• P2P screen. Used for point-to-point or peer-to-peer programs. This is useful if you have applications running on your computer that exchange data directly over the network with other computers (for example, torrent clients).
• Internet chat screen. Useful if you use, for example, ICQ.
• Firewall. Protection against network attacks from the outside, for example, from a computer that (by hook or by crook) has connected to your local network.
• Scenarios screen. Intercepts all scripts running on the system.
• Behavior screen. Detects unusual and suspicious behavior of programs (and draws the user's attention).

Most screens are customizable. To do this, click on the "Advanced settings" button in the corresponding screen window.

The example below shows sensitivity level settings for a web screen.

As you can see for yourself, avast! offers quite a lot of settings that are intended rather for an advanced user, and we leave them outside the scope of our guide. An inquisitive reader will figure them out without much difficulty: avast! offers not only hints next to each field and button, but also an intelligent help system in Russian. To access it, just press the F1 key on your keyboard or the question mark button in the program.

Sometimes the protection provided avast!, Comodo Firewall And Spybot turns out to be not enough. Despite our desperate efforts, malicious code still penetrates the system. Then we have to look for more effective ways.

Antivirus CD/DVD

Some antivirus manufacturers offer tools for creating special CD/DVDs. With their help, you can perform a “clean” (virus-free) boot of your computer and deal with infected hard drives. A CD/DVD can usually be downloaded as a single ISO file (called a "disc image"). ISO is a universal format; it is “understood” by various programs for working with CD/DVDs. Using such a program, you can turn an ISO file into a bootable CD or DVD, which is necessary for fighting viruses.

The sequence of steps is as follows:

• Download a program that will help you deal with malicious code, like those described in our guide.
• Create a bootable antivirus CD or DVD. To create (sometimes say “burning” a disk), you can use some free program, for example, ImgBurn.
• Insert the disc into the drive of the infected computer.
• Turn off the computer (as usual). We disconnect it from the Internet - physically remove the wire or disconnect the wi-fi adapter, depending on the method of connecting to the Internet.
• Turn on the computer and boot it from the CD/DVD.

Advice for advanced users. Your computer (depending on configuration) may have a boot sequence set to "hard drive first, then CD/DVD". In this case, the computer will always boot from the infected hard drive. To change the sequence to "first CD/DVD, then hard drive", you need to enter the computer's BIOS and change the corresponding setting. Entering the BIOS is most often done by pressing the Del key or another key at the very beginning of boot (when the first information appears on the black background of the screen). BIOS manufacturers prefer different interfaces, which are always displayed in English. If you are not confident in your abilities, it is better to contact a knowledgeable person. ATTENTION! Incorrect BIOS settings can prevent your computer from booting correctly!

Some very old computers may not have the ability to boot from CD/DVD at all. Then, unfortunately, the method described in this subsection cannot be applied. Fortunately, such computers are becoming fewer and fewer.

• We turn on the Internet connection and allow the antivirus program to download the latest updates.
• We scan your computer's hard drive(s) for viruses.

Here are some examples of "antivirus CDs":

After performing a clean boot, you can use other scanner programs:

• HijackThis and other tools from Trend Micro's Clean-up Tools.
• RootkitRevealer from Microsoft's Sysinternals kit.

To deal with malicious code for sure and completely, you can use several of these utilities in succession.

Reinstalling Microsoft Windows

The last resort against viruses (when other methods have already been tried) may be a complete reinstallation of the operating system. This is a relatively long process, but it allows you to “start from scratch.” If you do everything carefully (nothing is fundamentally difficult), you will not lose any of your working files. Reinstalling Windows only affects the system files of the operating system itself, and not user data.

It must be said that on some computers, reinstalling Windows helps “in one fell swoop” to solve other problems, for example, system overload with programs installed in the right place and in the wrong place, errors in the registry, etc. It turns out something like “spring cleaning”.

ATTENTION! Before reinstalling Windows, make sure that you have at hand all the license keys and serial numbers for paid programs installed on your computer, as well as for the distribution of Windows itself. You should be aware that a complete reinstallation of Windows will remove all installed programs and will have to be reinstalled. Therefore, remember (write down) the settings of the most important programs.

The sequence of steps is as follows:

• We create a backup copy of user data (documents, spreadsheets, email files, etc.).
• We boot the computer from the Windows distribution kit to the CD/DVD.
• Install Windows following the instructions on the screen, formatting the system hard drive.
• We allow Windows to download and install the updates necessary for the operating system.
• Install avast! (or other antivirus program), let it download and install the updates it needs.
• We install (and, if necessary, update) other programs.
• Only after this do we connect the disk with the backup data to the computer. We scan it for viruses and other malicious code.
• Restoring data from a backup.

Questions and test

Questions

Question: I have a lot of files on my computer. Would it take too long to scan these files every time you boot your computer?

Answer: May be. Perhaps you should be content with scanning the entire system once at boot, and then disable this option and trust Avast!'s resident protection.

Question: Should you install two antivirus programs (or more) on your computer to ensure more reliable protection?

Answer: Not worth it. Antivirus programs may conflict with each other. One of them may consider the behavior of the other suspicious or even dangerous, and the user will have problems. Use the program that you like best and that you trust.

Question: I heard that the antivirus... is better than avast!. This is true?

Answer: It happens that antivirus programs behave differently in critical situations. What one antivirus could not “cure” or even detect, another can, and vice versa. In general, modern advanced antivirus tools (such as avast!) cope with the vast majority of viruses with approximately equal success. If you don't like avast!, you can uninstall it and install another antivirus, even a commercial one, since such programs are usually inexpensive.

2017

Avast 2017

Once the file has been analyzed, the Avast team provides the user with information about whether the file is dangerous - this mechanism allows for faster response times to emerging threats, and also makes a major contribution to improving overall Internet security.

Along with standard protection, the Nitro release is equipped with the following features:

• Reduced impact on the system
  • With this version of Avast Antivirus, your computer boots on average 11% faster. The antivirus download speeds up due to the smaller program size; security analysis in the cloud frees up the processor's processing power for other tasks. According to an independent study by the testing laboratory AV-Comparatives, Avast affects the system half as much as Windows Defender installed on Windows 10.
• CyberCapture
  • CyberCapture technology, developed by Avast Threats Labs to analyze unidentified files, protects and alerts users to new threats. This allows Avast's team of virus analysts to provide real-time protection against any new threats before they appear.
• Monthly updates
  • Avast releases monthly software and component updates to improve threat detection and security. Updates happen automatically.
• Scanning HTTPS traffic
  • Avast web shield scans all HTTPS sites for malware. Today, about 30% of all Internet traffic passes through HTTPS. On average, Avast detects 50,000 infected unique HTTPS URLs every day and protects approximately 3.2 million users each month from downloading malware or accessing HTTPS sites that distribute malware. An independent study from Concordia University in Montreal, Canada, found that Avast offers the most effective HTTPS traffic scanner.
• Upgraded home network security
  • The Nitro update offers improved router security, which includes detection of 12 additional types of vulnerabilities and protection of users from threats such as DNS spoofing, banking hacks, and complete protection of network drives and routers.
• Improved SafeZone browser
  • SafeZone browser has become available to all users of free and paid Avast antivirus products. In the new version, the browser works even faster, protecting user privacy by automatically moving sessions into an isolated environment - for absolute privacy when browsing, shopping and banking online. The browser offers more comfortable navigation and contains an ad blocker.

2013: avast! 2014

Referring to their own data, Avast developers reported that in February 2011, the installation base of their antivirus amounted to 7.27 million users. This number, according to Avast’s explanation, included only those copies of the antivirus that requested an update to the database at least once in the last 30 days.

If Avast's own calculations are correct, this means that the market share of the free antivirus has grown by about 56% over the past year, up from 4.6 million in the first half of 2010.

The main difference between the Avast! 6.0 included the inclusion of AutoSandbox technology for launching suspicious applications and opening suspicious files in an isolated virtual machine, and this technology will be available even to users of the free version of the antivirus.

According to the developers, the future product avast! 6.0 will be the world's first antivirus to offer virtualization support in a free version. AutoSandbox virtualization technology allows you to create a secure boundary between known dangerous and known safe content. Combined with powerful traditional antivirus technologies, avast! 6.0 should provide users of paid and free versions with the highest level of threat blocking.

To turn on the test virtual machine, just one click is enough - after that, all suspicious files are opened in this virtual machine. If the open file turns out to be malicious, the virtual machine will simply stop, but the user's main computer will remain undamaged. A user of AutoSandbox technology has three options for dealing with potentially dangerous files: run the file in the AutoSandbox virtual machine, run the file without virtualization, or completely cancel the action of opening the file.

Avast

Anti-virus program for Microsoft Windows and GNU/Linux operating systems, as well as for PDAs on the Palm and Windows CE platforms. Development of ALWIL Software, founded in 1988 in the Czech Republic. The company's head office is located in Prague (employs 90 people). Available in several versions: paid and free for non-commercial use.

Today we will talk about Avast Free Antivirus 2017. This is a free antivirus for Windows, Mac OS and Android, which has been installed by hundreds of thousands of users in the Russian-speaking segment. Some users like the fact that they don't have to pay for antivirus features, while others value reliability and protection against threats.

Avast versions: Free, Internet Security and Premier

Free Antivirus(Basic protection). Includes protection against cyber threats, potential threats, in-game shutdown, and secure password storage.

Internet Security(Comprehensive protection). Unlike the basic version, Internet Security includes an anti-phishing module, protection of banking data, home network and anti-spam filter. You can download Avast Internet Security antivirus for free for 30 days.

Premier(Maximum protection). The difference between this edition of Avast and Free and Internet Security is the program update and file shredder. You can also download Avast Premier as a trial version.

System requirements for installing Avast

The system requirements for installing Avast are quite humane - Windows XP (Windows 10 is best), 256 MB of RAM and 1-2 GB of hard drive space for installation. This is quite enough for Avast to work normally without constant user complaints about the brakes.

Avast Free Antivirus 2019 - Free antivirus program. Full protection with high reliability. Successfully used in many home systems.

Avast antivirus has a pleasant and accessible interface, simple, intuitive settings that provide access to all protection parameters. This provides a high level of detection of all kinds of computer threats, including viruses, spyware, and Internet worms. Has a built-in anti-spyware module. Capable of identifying deep-seated threats in the form of rootkits, since it has a built-in anti-rootkit.

Avast! Free Antivirus constantly monitors the system in real time, scanning running files and processes. To ensure greater protection, it makes sense to periodically run an existing regular scanner with a full scan of the file system and the ability to scan inside archives. In addition, the antivirus protects its own modules well.

Avast! Free Antivirus checks for the presence of malicious code, first intercepting all incoming and outgoing mail correspondence, as well as Internet pager messages and files distributed using p2p technology. Using a Web screen, it protects against unwanted sites that distribute viruses and infected scripts. There is a firewall.

The new CyberCapture technology is a cloud-based file scanner for unknown threats. Suspicious files detected by Avast! first placed in a secure, isolated area and instantly transferred to the Avast laboratory, where a thorough analysis and identification of the threat is carried out. Unknown executable files downloaded from the Internet are subject to such an analysis, usually those that have the status of suspicious, that is, not available in the databases, but whose actions are determined by the antivirus as similar to the behavior of some viruses. Avast provides real-time cloud updates using streaming technology. The antivirus informs the user about various events (updates, threat detection and other messages) with pop-up windows.

Avast is free only for non-commercial use; for legal use in commercial organizations you must purchase a license.

Since the sixth version in Avast! Free Antivirus has made available an automatically launched safe environment for running suspicious applications, the so-called Sandbox, similar to that used in . Previously, this feature was only available in the commercial version.

In the Avast Free 2015 version, a new tool has been added - a home network security scanner, which can prevent hacking of a network, router, or wifi devices. Smart scanning (SmartScan) combines several types of security checks, including, in addition to anti-virus scanning, additionally updating installed programs, searching for vulnerabilities in the home network, and checking system performance. The "Remote Assistance" function was removed from new versions, since it was not popular; users are more willing to use specialized programs like.

The status of protective screens is displayed in the "Active protection" tab of the program settings.

Avast gives access to numerous program settings for those who like to more precisely tailor it to their requirements.
