Avast and the new virus. Comparison of Avast Free Antivirus and Kaspersky Free antiviruses

Hello, dear friends!

Today we’ll talk about the free Avast antivirus, or more precisely, how to fix the problem of starting it. So!

The other day I received a dozen emails asking for help in eliminating the following problem with this antivirus. I quote: “Hello! I have this problem: I’ve been using the free Avast antivirus for several months now and everything has been fine. but three days ago I ran into a problem that I still don’t understand. The problem is this: when the system starts, at the bottom of the monitor (in the tray) the Avasta icon is crossed out with a red cross. I hovered the cursor and saw that the system was not protected. When I try to start the protection, nothing happens! That is, nothing at all! I already rebooted the system ten times, and manually turned something there - zero! What to do? Do you really have to take down your antivirus? Tell me, is there any way to start it again?”

Are you unfamiliar with this situation? This happens quite often with Avast and here's why. When visiting certain Internet resources, Avast often informs you that the site you are about to visit poses a threat to your computer. To confirm its “words”, the system even shows you a banner with a detailed address and name of a possible “Trojan” or virus. And then he reassures you, saying, don’t be afraid, the system has blocked access to the malicious site. But in reality this is not so! In 80% of cases, a virus or Trojan has already “settled” in your system and quickly registered itself under some harmless pseudonym. (From the author: most “Trojans” cannot be detected not only by the “teapot”, but also by the free antivirus “Avast”. The maximum that it is capable of is to catch and kill several “lousy” “rootkits”. You should not blame the weakness of this antivirus : after all, you are using a free version! What do you want for free? Just remember: Avast is far from the best antivirus, especially its free version. And finally, the latest version of Avast often conflicts with the system and blocks many websites that you previously logged in without problems. I’ll say right away: this report is not Avasta’s “black PR”, but simply food for thought). But let's continue. Having settled somewhere in the endless depths of the system, the Trojan easily and simply blocks the operation of your Avast antivirus, as a result, you are denied access to managing your own antivirus. Paradox? To some extent, yes.

Now let's talk about the main thing: is it possible to somehow push the antivirus off the ground and start it again? Well, you can try: in the end, you will always have time to remove your Avast. So, we perform the following algorithm: “Start” - “Control Panel” - “Add or Remove Programs”. Find your Avast in the menu and click on the virtual “Replace/Delete” button. You will see a window with three actions to choose from. Select the “Update” action. You will see a window in which the update will take place - downloading a file (package). Wait for the download to complete and click on the “finish” button. After that, open the Avasta interface and see the “Fix” button there. Click on it and the antivirus will work! Miracles? No, friends: you just eliminated the consequences of a system or software failure. However, I still advise you to think about changing a free antivirus: freebies do no good! At the very least, you can install some other free antivirus and see how it works.

All the best to you and see you again!

After registration, you can receive your personal free license key by email. The key will be valid for only one year. After this period, we recommend re-registration.

The free antivirus also features a completely updated user interface, which is not difficult to understand. The antivirus does not remove anything unnecessary and does not prevent the launch of safe programs, nor does it interfere with their quality and reproductive performance. The main components of the free version of Avast:

• The anti-virus scanning module is defined by its high performance;
• Protection even from hidden traces of the presence of intruders and malware;
• Excellent resistance to spyware;
• Automatic sandbox technology - AutoSandox;
• Web browser add-on – WebRep;
• Blocking malicious websites;
• Russian-language interface.

As a rule, free content is characterized by an incomplete package of services. Avast antivirus refutes this fact. So use it with confidence and don’t deny yourself anything!

What are the limitations in the free version of Avast?

Avast is officially a free antivirus. Let's say, for a cautious and inactive user, Avast alone will be enough, which is configured by default and does not require additional gestures. Thanks to the little details that were thoughtfully thought out by the developers, the verification speed was achieved. It is also recommended to install Avast for people who have limited Internet traffic. Well, I think you have already decided for yourself whether Avast is enough for you or not.

We recommend combining Avast with the also free DrWeb CureIT program! You can find these programs on the official websites of the manufacturers. The utility is updated quite often, which adds to your guarantee of protecting your computer.

The DrWeb CureIT program scans memory objects, drivers, autorun and other critical objects. After checking with this product, install Avast. The program will ask you to restart your computer - you should not do this. Further checking will work without rebooting. Do a detailed check with Avast. Afterwards you should reboot. All viruses and threats found will be removed. To be sure, let’s check it again using the method described above.

Comparison of Avast with other antiviruses

A large number of antiviruses are offered to your attention in the markets and on the Internet. But no matter how sad it is, none of the antiviruses can give a 100% guarantee. You also need to take into account the fact that the user “cooperates” with the security program installed on the computer. The security of your files and software depends a lot on what sites you visit. For home use, it is better to choose free antiviruses. Kaspersky is quite good, but also expensive.

Avast detects a large number of malware and viruses, which allows it to compete with paid and expensive programs. The unique Avast mode has not yet been implemented in any antivirus. When the system starts, the virus scan mode also starts.

The advantage of this mode is that it is impossible to completely clean the system of viruses if they are launched along with infected programs. The only way to kill such a virus is to disarm it before the program is launched on the system.

A huge number of positive reviews, the uniqueness of the interface and some modes should attract your attention. And in addition, you will get all this for free. If you want to protect your work and the operation of your computer, we recommend choosing Avast!

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.

The installation process is simple:

Run the downloaded installer file,
- decide whether to install the Google browser additionally (if not, then uncheck the boxes).
- The program will begin to install,
- Once the installation is complete, the Avast Free main window will appear.

On April 22, 2019 it became known that AVAST and Allsoft Ecommerce continue to expand their partnership in Eastern Europe. Having launched online sales of antivirus in Poland, Allsoft begins online sales of electronic vendor licenses in the Czech Republic. The Allsoft Ecommerce platform is a flexible solution for online sales of digital products and services around the world. It allows you to increase the amount of the average check, supports email marketing, and also has extensive capabilities for working with abandoned carts - when the buyer selected and added an item to the cart, but did not pay for it.

For the project with AVAST, the online shopping cart was completely localized taking into account the requirements of the local market. Payments are accepted in the currency of the Czech Republic - Czech crowns. Buyers can pay for their order using one of the convenient payment methods, including payment using a bank card, online banking with access to the most popular banks in the Czech Republic, classic bank transfer and PayPal. Buyers are assisted by phone and email from Allsoft Ecommerce contact center specialists in Czech 12/7. They communicate by mail, receive incoming calls and make outgoing calls, helping with all issues related to the purchase and installation of software.

We studied the online sales market in the Czech Republic and offered the client a customized Allsoft Ecommerce solution that is optimally suited to Czech users. This helped increase AVAST's cart conversion by 33% in the number of orders compared to another ecommerce provider. In February and March 2019, A/B testing was carried out in which AVAST divided its website traffic between two ecommerce providers. Allsoft Ecommerce demonstrated efficient operation, showing better results compared to its competitor. Marina Kuznetsova, director of development in non-CIS countries

Avast 2017

After 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.
