WHAT VIRUSES ?

A computer virus is a program that travels over the Internet, destroying computer programs and causing them to stop working. Antiviruses are now produced against these viruses. The first information about viruses can be found in the 1977 fictional work of the American T. J. Ryan. In this work, it is said that
7000 computers were infected with a virus. A virus is also a program according to its structure, but it is harmful! Currently, viruses have a very wide classification. They operate in a wide range. For example: Kaspersky antivirus can detect 1.5 million viruses (2009 data). The world's first virus program was placed on the Internet in 1988 by Cornell University graduate student Robert Morris Jr. This virus performed its activity by exploiting the flaws of the Unix operating system for malicious purposes. The virus created by Robert Maurice caused a lot of damage. And Robert Maurice was sentenced to a long prison term, but his name remained in history for a lifetime.

Nowadays, all computer users are familiar with the concept of a virus. Met with this little program several times. In many cases they were defeated. If you know, this article is about viruses.

A virus is a program created by a programmer, which destroys the smooth operation of the computer and, as a result, prevents the computer from turning on. These programs are mainly downloaded to the user's computer via the Internet.
Of course, this program appears on his computer without the knowledge of the Internet user. The program that fights against them is called an antivirus (about this in the next articles).
Viruses behave differently on computers. Some of them fill your computer with unnecessary files, some of them use up a lot of RAM and freeze your computer, and some of the viruses harm you by deleting your necessary files or system files. In order to avoid them, it is necessary to know the type of viruses, that is, which virus does what and how to avoid it. Below are their types

A spyware dialer is a malicious program that is installed on a computer and tries to use the dialing features to call other numbers, often running up expensive phone bills for the victim. A dialer is unlike other types of spyware, though it is sometimes included with free software-type downloads.
They are difficult threats to detect however, and it is not easy to prove that the dialer has been responsible for running up telephone bills. Similarly, it is difficult to distinguish between a legitimate dialer and a spyware one, something that makes this type of infection hard to identify. Spyware dialers are however easy to eliminate once the file where it resides has been identified.
