Free versions of antivirus
In this article, we are going to talk about the free versions of the most popular antiviruses that are quite usable, protecting your computer from viruses and emergency cures for viruses if necessary.
For example, if your regular antivirus finds no threats, you can use the free version of a popular antivirus when malware is suspected, without buying a new one.
A computer virus is a program or piece of software code capable of replicating itself, infecting other (running) programs, and spreading without the user's knowledge.
The main ways in which viruses appear on a computer:
- CDs and DVDs
- USB storage media (flash drives)
- Local area networks and the Internet
The action of computer viruses is always malicious. Even if a virus doesn't overtly harm the system, its presence disrupts programs, takes up hard drive space, and disrupts the allocation of computer resources. The most virulent viruses can delete user files and data, spread advertising (spam) through emails on behalf of users, "steal" data (passwords) from user accounts. A virus can corrupt the entire operating system or even damage the computer's hardware. There have been cases in history where a computer virus has brought down entire organizations, such as airports or television studios. Thousands of computer viruses are known to spread over the Internet.
For a detailed classification of malware, see the virus encyclopedia http://www.kaspersky.ru/wiset.

Certainly, it can be said that computer viruses are detrimental to system performance. But is there a way to protect yourself from this problem? Yes, actively developing antivirus programs have been created to protect against computer viruses. Today, the antivirus software market has more than a hundred representatives. Let's consider the most popular among users:
- trend Micro
- Antivirus Kaspersky
- Dr Web.
The variety of antivirus programs is due to the different algorithms to search for and cure viruses. However, despite the wide range of antivirus capabilities, none of them guarantee 100% computer protection. To a large extent, it depends on the literacy of the user himself.
Currently, the price of an antivirus package for a PC is on average 2.000 rubles. And, if a few years ago, most manufacturers represented an unlimited term of use of antivirus software, now, for the most part, the term of the license for a computer is valid for one year.
Of course, for commercial organizations, data security is not only of practical importance, but also of economic importance. And to keep them safe, you need to use advanced data protection programs, including antivirus. But is it reasonable to pay an annual fee for an antivirus installed on a home PC, the malfunction of which is unlikely to have serious financial consequences?
