Antivirus programs are one of the keys to a long and consistent work of the computer and the operating system. Therefore, they must be installed first.
Malware protection
In the era of globalization and the widespread distribution of the Internet, the computer is under constant threat of exposure to the system of various malicious programs, the main purpose of which is not only to damage the computer and the system, but also to possess various confidential data (passwords, logins, payment card numbers, etc.)). All this forces PC users to look for reliable ways to protect their computer from damage, and antivirus is the very first defender.
Restoring your PC to work
Many antivirus programs, in addition to protecting against malware, have built-in tools for backing up data from your computer's hard drive, as well as tools for restoring it. With the help of antivirus software, it is possible to create restore points, as well as create a virtual "sandbox", the main purpose of which is to separate the activities of a potentially dangerous program from the activities of the operating system. Therefore, the role of antivirus in the daily work of a PC can hardly be overestimated.
The price of antivirus products ranges from a few dollars to hundreds. At the same time, they may not differ much from each other in terms of their functionality.
System security control
Any anti-virus program has its own anti-virus signature database. It is necessary so that the antivirus always has the latest data on types of malicious software. This database needs to be constantly updated, therefore, for the effective operation of anti-virus programs, a constant connection to the Internet is required. You should regularly check your system for viruses and files that, when started, can damage your computer and system. To better protect against them, many of these programs include a system of monitors that protect the system either while it is running or while trying to start programs.
Firewalls are often included in anti-virus packages - programs that serve as defenders against hacker network attacks.
Choosing an antivirus
The question of which antivirus to install on a computer is always controversial. On the one hand, it should not slow down the activity of the system, and on the other, it should reliably protect against all potential threats. There are a lot of both paid and free programs of this level. Among the paid ones, the most famous are software products from the Kaspersky Lab, as well as software called Dr. Web. Such programs are supported by constant technical support of users, participation in promotions and testing of new software, etc. But there are free counterparts, such as Avast !, Comodo Internet Security, Avira, etc., whose quality is not inferior to their paid counterparts.
