Comparative test of Dr.Web, ESET, Kaspersky and Norton. Which antivirus is better, Kaspersky (Kaspersky) or Dr.Web (Doctor Web)

Which antivirus is better, Kaspersky or Dr. Web (Doctor Web)!

In this article I will not touch on other antiviruses. I just want to talk about these two.

I'll tell you my case. When I first went online, I didn’t have an antivirus. Then I thought about this question. I found two free ones online Kaspersky antivirus and Dr. Web.

Of course I installed Kaspersky (you guessed it right away). 78.53% of users would do this. Installation and activation went fine. Afterwards, when I came home from work (a certain number of days had passed), I discovered that the computer was working somehow wrong. I tried to run the antivirus, but it wouldn't turn on. I had Kaspersky antivirus on a flash drive. I inserted the USB flash drive and wanted to reinstall the antivirus again. But the virus broke the antivirus again. I went online and wanted to download some other antivirus program. But as soon as I connected to the Internet, the virus immediately stole from me windows key. Windows began to appear on the screen with the message that you are using non-licensed Windows. It's all over reinstalling windows. Now I installed Doctor Web.

Let's now figure out which antivirus is better. In reality, there is no such thing as 100% protection. But each antivirus has its pros and cons. To be honest, Kaspersky has the best virus database, but its methods often lead to system freezes. And one more big disadvantage: all viruses are initially designed for Kaspersky. The main task of the virus is to destroy the antivirus program, and then quietly reproduce. So, by installing Kaspersky, there is a possibility that your antivirus will be broken. Also, when a virus gets onto a computer, it enters the antivirus database and deletes itself from the database. And the antivirus then does not recognize it as a virus.

As for Doctor Web, it allows viruses to enter your computer and allows infection system files and only then finds these infected files and disinfects them. But he has very good program“Dr. Web CureIt" "Dr. Web CureIt” does not require installation and can be launched from any media. It has its own virus database. Simply by launching it from any media, you check the entire computer.

First you need to turn Windows into a fortress, the OS can be fine tuned and sent to smoke half of the malware!

Regular updates reduce the likelihood of your computer becoming infected.

Also, do a full scan of your computer once a week or more often, it all depends on how often you use the computer.

You also need to properly configure your antivirus software, no matter which one you use.

Of course, no antivirus can provide 100% security, because... There is a “human factor” - the rules of online behavior must always be followed.

IN modern world, where very strongly developed computer technology, the use of a PC, laptop, tablet is an integral part of our life. But you need to use technology wisely. If you have access to the Internet, then you need to take care of how to protect your PC from numerous harmful viruses and programs. In this case, the most important thing is to get ahead of the virus by installing an antivirus on your computer.

All over the world there are a huge number of programs that combat computer problems and help get rid of worms. But among all this diversity, the main and most popular are Kaspersky, Nod32, Avast, Dr. Web. All these antiviruses have been fighting viruses for many years and are constantly undergoing updates. Below we will make a comparison to determine the leaders.

Before we begin, we need to decide on the basic criteria by which we can determine the significance of each of them.

Degree of protection

This is the most important criterion, because good antivirus should easily detect malware and viruses that have entered your PC. And he must do this instantly, so that it does not have time to spread throughout the computer and ruin everything on it. But not every antivirus can easily defeat a virus. It all depends on how “developed” the virus is and how long ago it was born. And not everyone is able to detect some viruses due to their backwardness.

Kaspersky is one of the leaders in this regard. This antivirus is capable of detecting almost any virus that appears on your PC, no matter how strongly it is hidden from the user. You won’t even think that some virus wants to harm you, and Kaspersky will already be trying to remove it. The antivirus will even be able to find the virus that is hidden in the archive before it is opened. In addition to detecting viruses, in case it manages to slip through Kaspersky’s vigilance, it is possible to completely save your credentials on the Internet, automatically performs backups according to a given schedule, and has a cloud for storing information up to 2 Gigabytes.

Nod32 not only allows you to detect and promptly counteract viruses, but also has the ability to disinfect files that have been subject to virus attacks, or otherwise, delete the file from the system altogether. But you shouldn’t trust Nod32 so calmly, as there are plenty of glitches. In addition to detecting viruses, Nod32 can also detect secure files, as well as malicious ones that interfere with the operation of the PC and take up time. Among other things, messages often appear in the antivirus program: “The maximum degree of protection is not guaranteed.” Such problems may also occur empty space, without any prerequisites for this.

One of the leaders in free customer service is Avast antivirus. As for the free version, it works great. But he is still very far away from fighting on equal terms with the giants Kaspersky or Nod32. It makes many mistakes in identifying viruses, and it can miss them even before scanning. Besides, Avast is Avast and nothing more. There are no new versions at all, unlike Nod32 or Kaspersky.

Dr.Web is very advanced technologically. His inner work so complex that it is unlikely that any other program can interfere with it. He copes with high level with various virus programs, deletes infected objects, and prevents them from entering the computer. It works great on both legacy models and modern multi-core ones.

Easy to install and configure

Looking at all the variety of PC protection, you also think about which antivirus is better to install. After all, they all work differently with the system and in different proportions take away the performance of the PC.

All possible antivirus programs are not difficult to install. You just need to run the program installation file and simply follow the instructions. No knowledge in this direction is required here. To use the antivirus 100%, you need to register. So it’s not even worth determining the best or the worst here.

All antiviruses create load on your computer in different ways. This, in turn, in some cases, makes the PC less “alive”; programs run everything very slowly. So which antivirus should I download and install for my computer?

Kaspersky will probably be the “leader” here. It puts a lot of load on the PC system. This is noticeable from the first minutes of using this antivirus. During a system scan or when opening any files, this becomes more pronounced, as the computer begins to freeze. If you still prefer Kaspersky, then you need to purchase personal computer with higher performance.

Nod32 uses minimal PC resources and works very quickly. It is one of the fastest and does not interfere with work on a PC. That is, practically no changes will occur in the system after installing the antivirus program. Absolutely any computer with minimal requirements is suitable for its use.

Avast also uses minimal computer resources. For its operation you only need minimum requirements and in parallel running programs, games, videos, it has virtually no effect. The system scan is quick. It’s not for nothing that he was awarded the title for the fastest antivirus monitor, although this was in 2010. Much water has passed under the bridge since then.

Doctor Web has approximately the same characteristics. It works almost unnoticed by the user and has minimal impact on performance. True, it is slightly inferior to the same Nod32 or Avast. But, despite this, the Web has much more functions and capabilities than the free Avast.

Additional functionality

In addition to the main function - protecting your computer from viruses and malware, each of them also has additional ones, which set it apart from third-party antiviruses.

Kaspersky automatically backs up all files on your PC, thereby protecting them from being “eaten” by a virus, and can also be restored damaged files. When making payments on the Internet, this antivirus program first checks the authenticity of the sites. You can also prevent children from accessing some sites by using the “ Parental Controls", and also do it on certain days and at convenient times.

Antivirus Nod32 also has a sufficient number additional functions, among which are:

• As soon as you turn on your computer, the system begins to be scanned for viruses and other threats;
• Once the scan is complete, the computer can shut down on its own if you wish;
• It may automatically switch to energy saving mode, this applies to using the program on a laptop;
• The antivirus program will also automatically start scanning flash cards and disks inserted into the PC;
• When any updates appear, Nod32 will automatically install them on your computer.

Doctor Web is constantly improving existing functions and over time there are more and more of them. They are somewhat similar to the capabilities of Kaspersky or Nod32. It also saves your computer's data and helps you recover it if it is eaten by a virus. Can be used for quarantine external drives, such as flash cards.

Updates

Over time, new viruses, as well as old, but more modified ones, constantly appear on the network. It is for this purpose that there is an update to systems to detect these nasty things.

Kaspersky updates automatically, except if you remove it yourself this function to make your PC run faster. Updates happen very often.

Node 32 is also updated automatically, but only when critical updates appear on the network. Here you can configure the frequency of updates yourself. Here you do not have to disable the system update, since the program itself has virtually no effect on the performance of the computer.

With Avast, everything is a little more complicated. The update occurs when you visit the menu, where you can both update and install new version antivirus.

If you want to install a new version of Doctor Web, you will first need to uninstall the existing one, which is not entirely convenient. But the update already occurs automatically and without problems.

Mobile versions

In addition to using an antivirus on a PC, it is also important to install it in mobile phones. But which antivirus is best to use on a mobile device?

A nice feature from Kaspersky on mobile is anti-theft, which allows you to block a stolen or lost phone. And so are the standard functions for protection against viruses and SMS spam.

Nod32 Mobile Security, in addition to protecting against viruses, also fights against applications that can uncontrollably send SMS messages from your phone, and the balance only decreases.

Among the disadvantages of Avast is the inability to work on Symbian and Windows Mobile. Working versions of the program can have the usual set of functionality, or additional ones (if you purchase the Premium package).

Doctor Web is very popular in protecting mobile devices. It will also help protect your phone in the event of theft or loss, allow you to create black and white lists, and track messages from third-party phones and resources.

Technical support

All antivirus programs have customer support available. But they all work differently.

Kaspersky Lab works online 24 hours a day and will give you an answer to any question or problem that arises in the operation of their product. But the disadvantage here is that they practically do not work with older versions of the antivirus.

Except usual care, Nod32 employees can receive remote access to your PC and do everything right without you. This is very convenient in the case when you are not particularly versed in its work and are not familiar with the sections.

Avast support is a little behind. There are instructions, take it and figure it out yourself. You can also seek advice on the forum, where both company employees will definitely answer you on all problems that arise, as well as site visitors and users of this antivirus.

When working with Doctor Web, if you have any doubts about the authenticity of a file, you can send it to the company and they will analyze it. Just like Nod32, Web has the ability to gain access to your computer and fix all problems.

Let's sum it up

Having considered 4 antiviruses, only one question remains unresolved: Which is the best? Each program has both its pros and cons. There is no absolute advantage in favor of one or the other. Kaspersky will help protect your PC at a decent level, although it will cost a lot of resources. For ease of work, as well as for those who like to play online on their computer, you should consider installing Nod32 or Dr.Web, as they minimally reduce the performance of the computer. Using Avast, you will receive minimal protection, although you will not have to pay anything for it, it is completely free.

It’s up to you to decide which antivirus is best to use. It all depends on the requirements for the program, the characteristics of your PC, requirements for advanced functionality, as well as the ability to pay for work and constant updates.

Let's say we have 49 copies of current malware, which are 100% known to antiviruses with modern databases. What could these antiviruses have done with them a week ago, when these malware had not yet fallen into the hands of virus analysts? How effective are the heuristics and proactive protection of modern internet security if you test it against real malware? And for this there is no need to invent a time machine at all - we’ll just preserve experimental antiviruses in virtual machines without access to the Internet, and after a week we’ll test them against a collection of the latest malware, which is already detected by these antiviruses with up-to-date databases. But the antiviruses of the past, of course, don’t know about this yet :).

We will use KIS, Dr.Web, ESET and Windows Defender as guinea pigs. All except the last one will run in Win 7. The last one will run under Win 10 - there is hope that the “ten” is better protected and even with a sieve like Defender, viruses will not pass through. Well, let's check.

Once again about testing

Here's what will be checked: detecting the virus, blocking the virus from launching and treating the infection. The first test will be performed with protection disabled - in scanner mode. For the second and third tests, the antivirus monitor will be turned on.

After all this, we will update the database and compare the resulting detection with the previous result. Since there are many viruses, “exhibits” for launch testing will be selected by the antivirus itself. We will launch those viruses that are not removed as a result of the detection test. It is stupid to try to run a virus that is in the antivirus database - any antivirus will block it. The most interesting thing is to launch a virus that is “unfamiliar” to the antivirus.

All viruses in my collection were divided into groups: Backdoor, Worm, Virus, and so on. A list of all “program heroes” will be provided later. As you can see, there is plenty to choose from.

Your ideas

Your ideas inspire us to new research. We have already taken them into account. So keep gushing - comments on the article and are always open to your suggestions for improvements :).

All operating systems are fresh (specially installed for this article), and the Internet was turned off immediately after installing the antivirus so that the databases remained old with a 100% guarantee.

Let's start testing with everything we know Kaspersky Internet Security. As you can see from the screenshot below, the antivirus was installed six days ago (24 days of free use left).

Disable the antivirus, unpack the archive with viruses. We do not activate the antivirus, but we run a custom scan (so that it does not run everything in a row, but concentrates on one folder) and check the Virus folder. I remember once at a gas station they managed to fill a 20-liter canister with 23 liters. So in the case of Kaspersky - in a folder of 49 files, he managed to find 80!

Apparently, several infections are packed into one file and the antivirus displays each of them separately in the list. Let's look at the detailed report.

As can be seen from the screenshot, 45 threats were found (out of 49). For some reason, the Trojan.Win32.Waldek.jsu virus was neither deleted nor quarantined: the antivirus simply did not process it, although it detected it. There are a total of 11 files left in the Virus folder.

Most of the viruses survived in the RansomWare folder. As you can see from the screenshot, files numbered 2, 4, 7 and 8 were not touched by the antivirus at all. It will be interesting to see the detection after updating the databases.

Well, now we activate the protection and try to launch the “surviving” viruses from the Virus folder. I ran the first two files from the RansomWare folder (numbers 2 and 4). File number 2 was recognized as PDM:Trojan.Win32.Generic. The antivirus detected dangerous behavior of the program, “precisely characterizing it as malicious.”

He suggested healing the computer by rebooting. We agree. Treatment began, the antivirus canceled the actions of the malicious program and simultaneously eliminated file number 4.

I didn't like the results of the treatment. After rebooting I didn't get a clean system. Something was trying to boot, and files created by the virus remained on the desktop. The antivirus cleaned up some things, but it seems to me that not everything. Along the way, the antivirus, of course, tries to treat objects created by viruses.

I continue to run files from the RansomWare folder (numbers 7 and 8). Immediately after launching these files, as in the previous case, there was no immediate response from the antivirus, which allows programs to multiply. The antivirus began to respond after the viruses tried to send emails. Nothing worked for them - I have neither an email client nor an Internet connection!

It’s interesting, but Kaspersky anti-virus did not respond to file number 8. Let's move on. From the Scareware subfolder I launch the only file with the same name. I wait a few minutes. There is no reaction from the antivirus, and in the meantime the virus is most likely doing its dark deeds.

From the TrojanCryptor folder I launch a file named TrojanCryptor (1). The cryptographer is the heavy artillery. There was no response from the antivirus either. But a window appeared.

About the ransomware

The Trojan launched, there seemed to be no response from the antivirus, but the data remained unencrypted, as was the case with another participant in this test. But one of the antiviruses allowed data encryption, as you will see below.

From the Virus folder I launch files numbered 4 and 8, then from the Worm folder - files 6 and 8. For some reason the first one did not start (it’s not only developers who make mistakes regular programs, but also virus writers). But Kaspersky did not react to the second one.

I run a full scan of the computer. Its goal is to identify objects infected with viruses and try to cure the computer. After the reboot, let's see what happened with the antivirus. To be honest, I was not pleased with the results. The antivirus reported that no threats were detected. Although the malware remained on the computer. I didn’t dig deep - I just opened msconfig and looked at the startup list. As you can see, the antivirus did not clean out everything.

When I restarted the computer, Kaspersky reported that it had decided to cure my computer - detected active process treatment, which resulted in the removal of the Ransomware (8.exe) file, as well as the worm (8.exe) file.

It looks like it cleaned out some malicious files. After treating the active infection, KIS again reported that there were no threats.

Well, it's time to update the databases. The databases have been updated and the computer has been rebooted. After the reboot, the recovery after infection wizard started, offering to fix some issues. After the wizard works, I reboot the computer again.

The master restored some things, but not others. Yes, autorun is cleared. But not completely - as you can see, there are still those who want to launch. -!RecOveR!* files created throughout the disk were also not deleted.

I give the antivirus another chance and run a full scan again - this time with new databases. No threats were detected; multiple files created by the virus remained on the computer.

Now repeat the detection test. I disable protection, unpack the archive and run a custom scan of the Virus folder. After updating the databases, Kaspersky neutralized all threats (49). In general, what was to be expected, because we specifically included in the test only real malware, known to the “antiviruses of the future.”

Dr.Web Security Space

A real monster was chosen from the Dr.Web line, installation file which weighs 466 MB, - Security Space. The smaller Katana product wasn't an option because it doesn't have a scanner.

Introduction

To protect your computer, work information and personal data, every user of the Windows operating system wants to find and install a modern antivirus on their PC, because No one wants to one day experience data loss, PC malfunction, or see a “black screen.” Accordingly, the question of choosing an antivirus arises.

Reading advertising articles from antivirus manufacturers, you are faced with the fact that everyone unanimously declares that their software product is the most advanced, modern and will not allow a single virus, not a single “worm” to pass through, the system will be 100% protected.

This is where the real puzzle begins - which antivirus is the best, how to make your choice? How to choose an antivirus? It all starts with searching for information on the Internet: you read articles by leading experts, visit forums and study people’s opinions, ask friends, and in the end you come to the conclusion that there is no consensus, and all the answers to the seemingly simple question “are you satisfied with your antivirus » contradictory.

I would like to make some comparison of antiviruses and at least approximately answer the question - which antivirus is better to install, I will immediately say not all of them, but the three most used in my opinion are Kaspersky Anti-Virus (Kaspersky Internet Security), Avast (Avast!) and Doctor Web (Dr.Web).

Why did I decide to make this comparison, because very often, when choosing one or another antivirus, people, They rely on the wrong criteria. Many people think that since free means bad, and paid, on the contrary, is good, or the more expensive the better, and so on. Let's see.

Purpose of the study: find out which of these antivirus programs is better: Kaspersky Anti-Virus, Avast, Doctor Web.

Object of study:Kaspersky Anti-Virus, Avast! and Doctor Web.

Subject of research:which of these antivirus programs is better: Kaspersky Anti-Virus, Avast, Doctor Web

Research objectives:

1) Explain what antiviruses are and how they work?

2) Study the literature about Kaspersky, Avast, Doctor Web antiviruses;

3) Highlight the pros and cons of antivirus software;

4) Conduct research among school students about which antivirus software they trust;

5) Processing the received data, constructing graphs and diagrams;

Relevance is to protect your computer and choose an affordable, convenient and effective antivirus.

What is a virus?

Viruses are programs, applications, sets of scripts, macros created to destroy, steal information, penetrate a computer, increase user privileges, and infect applications.

Computer viruses are programs that can “multiply” and secretly inject copies of themselves into files, disk boot sectors, and documents.

Activation computer virus may cause destruction of programs and data.

There are more than 100 thousand known viruses in the world. There may be more than a million unknowns - no one can know the exact numbers.

What is an antivirus?

What is an antivirus? Let’s immediately dispel one frequently occurring illusion. For some reason, many people believe that an antivirus can detect any virus, that is, by running an antivirus program, you can be absolutely sure of their reliability. This point of view is not entirely correct. The fact is that an antivirus is also a program, of course written by a professional. But these programs are able to recognize and destroy only known viruses. That is, an antivirus against a specific virus can be written only if the programmer has at least one copy of this virus. So there is this endless war between the authors of viruses and antiviruses, although for some reason there are always more of the former in our country than the latter. But the creators of antiviruses also have an advantage! The point is that there is large number viruses whose algorithm is practically copied from the algorithm of other viruses. As a rule, such variations are created by unprofessional programmers who, for some reason, decided to write a virus. To combat such “copies”, a new weapon has been invented - heuristic analyzers. With their help, the antivirus is able to find similar analogues of known viruses, informing the user that he seems to have a virus. Naturally, the reliability of the heuristic analyzer is not 100%, but still its efficiency is greater than 0.5. Thus, in this information war, as, indeed, in any other, the strongest remain. Viruses that are not recognized by antivirus detectors can only be written by the most experienced and qualified programmers.

Thus, it is almost impossible to protect yourself 100% from viruses (this assumes that the user exchanges floppy disks with friends and plays games, and also receives information from other sources, such as networks). If you do not enter information into the computer from the outside, it is impossible to become infected with a virus - it will not be born on its own.

So what is an antivirus and how does it work?

Essentially, an antivirus is a type of security tool that scans your computer for self-propagating malware (usually viruses and worms) and neutralizes it. To achieve this goal, the antivirus uses a number of detection technologies:

1. Signature detection
2. Heuristics and approximation
3. Virtualized simulation

Kaspersky Anti-Virus

Kaspersky Anti-Virus Kaspersky Antivirus, KAV ) - antivirus software, developed by Kaspersky Lab. Provides the user with protection against viruses, Trojans, spyware,rootkits, adware, as well as unknown threats usingproactiveprotection including a HIPS component.

Avast

Avast! - antivirus program for operating systemsWindows, Linux, Mac OS, as well as for PDAs on the platformPalm, Android And Windows CE. Development of AVAST Software, founded in 1991 in the Czech Republic. The company's main office is located in Prague. For home it is available in several versions: paid (Pro and Internet Security) and free (Free) for non-commercial use. There are also versions for medium and large businesses (Business Protection and Business Protection Plus) and versions for servers (File Server Security and Email Server Security). The product is certified by ICSA Labs.

The name avast is short for anti-virus advanced set. What's in English there is a word avast (“stop”), it was noticed later.

avast! Free is considered the most popular free antivirus. In total, avast antivirus! used by more than 160 million users worldwide.

Criticism

In general, criticism of the antivirus is positive. Very attractive for users free version, which has everything necessary for home user without any restrictions. The main advantage of avast! is its low resource intensity and high speed scanning. However, there are also disadvantages. One of the most famous is the inability to disinfect infected files (despite the fact that this function is present) and, in the vast majority of cases, such files are either deleted or moved to quarantine. Other disadvantages include the inability to remove a resident virus (located in RAM).

Tests and awards

Pros and cons of antivirus software.

It’s impossible to say exactly which antivirus is the best, it’s up to you to decide what to use, but let me make some comparisons to make it easier for you to make your choice. Let's start with Kaspersky.

Kaspersky Internet Security

Pros:

1. Judging by the ratings, the most powerfulantivirusof all that exist (if I’m not mistaken, not only in Russia, but also in the world).
2. Cope with all viruses malware, Trojans androotkits(of course, if it is updated, you need to have an Internet connection for this)
3. Minimal impact on computer operation. (indeed, when it works, in “passive security” mode, it uses very little RAM)
4. Well, there are a bunch of standard advantages present in all antiviruses, which I will describe below...

Cons:

1. The price on the Internet is 1,600 rubles for a year, but in stores it’s more expensive.
2. Kaspersky is not one of the most fast antiviruses.
3. Well, the third, perhaps the last of the minuses is that when full check it takes up a lot of computerRAMand it’s better to turn off all programs at this time...

Avast!

Pros:

1. There is a free version (which I use on my netbook, for example, and am very pleased with).
2. This is one of the fastest antivirus scanning files.
3. Updates are downloaded quickly and quietly, and you are notified about them after installation.
4. Voice prompts. That is, after performing any action, you are notified about it by a pleasant female voice.

Cons:

1. The free version cannot cope with some viruses, or rather, it ignores them.
2. Does not block “bad” banners and advertising on the site.
3. The free version must be registered within 30 days. (not big, but minus)

Dr.Web

Pros:

1. There is a free and VERY powerful utility called Curelt!
2. Quite good scanning speed.

Cons:

1. The Curelt! utility is constantly updated and about every month (or even week) you have to download a new version..
2. The paid version is not cheap...
3. And I also heard (but I only heard) that the key from your antivirus program can be stolen while you are using it (!!!).

We bought a computer and need an antivirus. Think about what you will use this computer for. If for entertainment, then it is more advisable to put free virus(For example, Avast! ). If it will serve not only for entertainment, but also for work, then it is better to install a paid antivirus.

Survey
The survey involved students in grades 8-9
(30 people)

Conclusion: According to our survey, the majority of students trust the protection of their computer to Kaspersky Anti-Virus, with the least number of votes received free antivirus Avast.

Conclusion

I chose this topic because I wanted to find out how to protect your computer from viruses and which antivirus is suitable for each of us - which antivirus is better and which is worse, their pros and cons.

I believe that the topic I have chosen will be of interest to many, since many cannot choose which antivirus program to install on their computer.

The results of my research and the survey I conducted showed that each antivirus program has its own pros and cons.

I think, in the best possible way protecting your computer is to install on your computer, for example Kaspersky antivirus and additionally free utility Curelt from Doctor Web. At the end of each week, scan your computer for viruses, first using Kaspersky antivirus, then using the Curelt scanner.

Many of my friends listened to my advice and use it, and also recommend this idea to others.
