Computer virus protection program. Free antivirus programs

Each user of a personal computer sooner or later thinks about the issue of protecting his device from virus attacks and hacking. This is very correct. Since some remembered it only after the harm received from the activities of malware or viruses. But it's not enough to just think about it. You need to be able to make the right choice among the many options offered, and then also figure out how to install an antivirus on a computer.

general information

The speed of development of modern digital technologies has a significant impact on human life. Computers are becoming more and more part of our lives, making it much easier for us to perform various tasks. Now it is impossible to imagine how they managed without all this before. A lot of different information is stored in a PC, and every day it becomes more and more, besides, part of it is confidential. In this regard, there is a task to keep it intact and safe.

Especially now, when banking operations, payment for goods / services, and transfer of important documents are carried out with the help of computers. The further you go, the more difficult it becomes to do so. There is a growing number of people who want to use user devices and the global network itself for their own selfish purposes. Security is especially important for active Internet surfers. Provides protection for specialized software, part of which are antiviruses, both paid and free. This is the question we will now deal with.

Install free antivirus

Having made sure that rootkits and similar malware do not disappear on their own, we proceed to the choice of protection. In principle, it is well known that there are a lot of antiviruses and they all differ from each other in their purpose and capabilities. Some of them, in addition to the paid version, can offer a full-fledged free one. Which of them are the most famous? These are Kaspersky, Nod 32, Avast, AVG, Panda, Dr. Web, Avira and some others. But, according to the conclusion of testing by AV Comparatives, only Avast has a decent free version for use on a home computer.

If you decide to install a free antivirus on your computer and it will be Avast, then you can stop worrying about its security. This program is built on the principle of modules, each of which works in real time, completely autonomously and provides continuous protection against its own specific type of threats. For example, there are screen modules such as file system, web space, mail, internet chats, P2P clients, heuristic screens of behavior and scripts. This number is the most optimal and is calculated based on possible threats.

How Avast antivirus is installed and works

If you have chosen this program, then with Avast you will not have a question about how to install an antivirus on a computer. Download from the official site, run the executable file, and then your device will do everything by itself. After 30 days of use, the trial period, you need to register. It is very simple and free. A year later, renew. Install “Basic Protection” and keep an eye on the process, as a paid version will be constantly offered. This antivirus monitors all running programs in real time and provides protection against rootkits and spyware.

You will also be warned about visiting dangerous sites and decide for yourself whether to visit them or not. Malicious scripts will be blocked. When in doubt about any application, run it first in a sandbox, a completely isolated environment. You do not need to take care of such an important matter as updating virus databases. The program itself, using Internet access, will do all this. Therefore, if you want to install a free antivirus on your computer and sleep “in peace”, pay attention to Avast. It has only two drawbacks: the intrusiveness of individual functions; sometimes makes inappropriate decisions.

Another serious protection is Doctor Web antivirus.

No less popular program used by many users is Doctor Web. Antivirus for a computer from this manufacturer is characterized by the fact that a 30-day free full version of the product is offered to evaluate its work. Having tested it during this time, you will be faced with a choice - to remove or purchase a commercial license. Let's talk a little about this application. Recently, its interface has been significantly updated. And not only this. The program has its own built-in firewall, anti-rootkit and anti-spyware, supports full, quick and selective computer scans. During installation, you will be prompted to activate the firewall.

There is a more advanced version of the program - Security Space, which includes a parental control function, with which you can set what your children are interested in in such a forbidden way and block access to unwanted sites. Doctor Web is updated automatically when the Internet is available. Thanks to the self-protection function, no outsider can change the settings of this application. And the Dr.Web CureIt utility, which scans your computer for free, is probably known to almost everyone. So, when choosing a good antivirus for your computer, pay attention to this option.

If earlier they had only a curing utility (Kaspersky Virus Removal Tool anti-virus scanner), now they also release real-time file system protection and protection against malicious sites on the network.

Yes, this antivirus has many different engines, each of which performs its task.

So we got our hands on the free Comodo Internet Security. This is a set of tools to protect your computer, which includes a firewall, antivirus and a proactive protection module. I will not describe all the features of Comodo Internet Security, because, in my opinion, they are standard and are present in most similar programs. The main difference between this program and the rest is its free and amazing reliability. When properly configured, the program allows you to secure your computer to the maximum. The other day I reviewed several comparative tests that various companies conducted, and the results of these tests quite surprised me. As an example, I will give the results of one of these tests.

Today I will talk about another free antivirus Avira Free Antivirus, which recently settled on one of my computers. The situation with it is special, since this antivirus is not a simple scanner, it does not need to be downloaded every time you need to check the system. This antivirus hangs in memory and does everything on its own. It downloads and installs updates on its own, independently checks the files accessed by the operating system and various applications.

A massive attack by the WannaCry ransomware (WannaCryptor, WanaDecryptor) has infected tens of thousands of computers in organizations and public institutions around the world. The malware exploits a known vulnerability described in security bulletin MS17-010 and a combination of EternalBlue / DoublePulsar exploits that can attack other vulnerable Windows systems on the same network. As a result, infection of one computer can lead to compromise of the entire corporate network in the organization.

After being introduced to a computer due to the successful exploitation of a vulnerability, the WannaCry ransomware encrypts all files and documents of certain formats by executing remote commands sent via the SMB protocol and spreading to other Windows computers on the network.

Perhaps you are too trusting, and therefore did not install an antivirus on your PC, or the license for your antivirus has already expired, or the antivirus you have installed does not provide maximum protection, and ... maybe your PC is infected!

For the vast majority of home users of Windows 7 and Windows 10, Microsoft's regular antivirus product is fine. In the Windows 10 operating system, it is already built into the system called Windows Defender and does not need to be additionally downloaded and installed. But for Windows 7 you will have to install by downloading the Microsoft Security Essentials distribution from the Microsoft website. In fact, this is the same product, but with different names for different systems.

Dr.Web CureIt! - an antivirus that is noticeably different from the usual programs for everyone. This utility does not work all the time, preventing malware from appearing on the computer. It allows you to cure an already infected PC from viruses, Trojan horses, rootkits, etc. This feature of Dr.Web CureIt! defines the scope of the product. It can be used periodically to check the reliability of the antivirus installed on the computer, as well as in cases where, based on indirect signs, infection of the PC can be suspected. In general, Dr.Web CureIt! hard to overestimate.

Continuing the popular theme of free antivirus, I want to mention another development that I met relatively recently and which I have not had time to write about yet. In theory, it would be possible to add this information to the original message, but I decided to put everything in the form of a separate note. So, today we will talk about a free antivirus from Kaspersky Lab called Kaspersky Virus Removal Tool.

An interesting free antivirus program is released by Microsoft Corporation. The utility is called Malicious Software Removal Tool (Malicious Software Removal Tool for Microsoft® Windows® OS).
