The operating system Windows 7, along with Windows XP, occupies a leading position in the OS market. But for the safe operation of the computer, it is necessary to install a high-quality anti-virus program that can protect the system from virus and Trojans.
Trojans and virus programs are the main threats when working on a computer running Windows operating system. Violation of the system, theft of confidential data, including bank card details - all this can be faced by a user whose computer is not protected by an antivirus program. Moreover, even the installed antivirus does not guarantee security - malicious software is constantly being improved, so the likelihood of theft of important data is quite high. Which of the dozens of well-known antiviruses will provide really high-quality protection when working under Windows 7? It is impossible to unequivocally answer this question, since each antivirus has its own pros and cons. At the same time, users have compiled an approximate rating of antivirus programs. Some of them are recognized as openly "full of holes", some work better. The first lines of the rating can be given to such anti-virus programs as Kaspersky Anti-Virus, Dr. Web and Avira. The arrangement of programs in this list is arbitrary and does not mean that one program is better than others. The undoubted advantages of Kaspersky Anti-Virus include high-quality protection and good technical support. In addition, it has a lot of settings to best protect your computer. The disadvantage of antivirus is that it is too "noisy" and does not let you forget about yourself, every now and then reminding you of something. You can turn off some reminders, but all the same, this antivirus regularly issues certain warnings that distract from the main work. Nevertheless, this is quite a high-quality antivirus, it is rightfully popular. Dr. Web anti-virus provides a combination of high-quality protection and stealth. The program reminds of itself only when it is really important - that is, when it detects malicious files or an attack on the computer (for versions with a firewall). The anti-virus databases can be updated both manually and automatically. At the same time, the database files are very compact, which is important for users with limited Internet access - for example, for those who work via a USB modem. Disadvantage of antivirus: its latest versions are noticeably "heavier" than the previous ones, so on computers with weak processors (approximately up to 1 GHz) and small memory (approximately up to 512 MB), it will at times significantly load the system. But for powerful computers, this is a very good option, especially the version of the antivirus with a built-in firewall. Avira software was created by German programmers. The main advantage is the availability of a free version, which provides quite reliable protection. The program is completely invisible during operation, in this it is very similar to Dr. Web. But when a virus or Trojan is detected, it immediately signals this and blocks the malicious file. It is convenient to work with Avira, it is quite a high-quality antivirus. The only drawback of the free version is the lack of a firewall. You can install it separately or use the paid version of the program. It should be understood that no antivirus can guarantee completely safe operation. Therefore, do not store confidential information on your computer in plain text, do not save passwords in browsers. Never open suspicious files or click on questionable links. By observing basic security measures, you will significantly reduce the possibility of a computer infecting with malicious software.
