Classification of anti-virus software

Anti-virus programs on pure antiviruses and antiviruses of a dual purpose are classified.

Net antivirus distinguished by the presence of antivirus kernel that performs the function of scan patterns. Principle in this case is that it is possible treatment, if known virus. Net antivirus, in turn, the type of access to the files are divided into two categories: control of access (on access) and on demand (on demand). Usually on access-products called monitors, and on demand-products - scanners.

ON demand-product works as follows: the user wants to check anything and prompts (demand), followed by a check. On access-product - a resident program that monitors the access to and the time of access checks.

In addition, the anti-virus software, as well as viruses, can be divided according to the platform within which this antivirus works. In this sense, along with a Windows or Linux to the platforms may include Microsoft Exchange Server, Microsoft Office, Lotus Notes.

Dual program - a program used in anti-virus software, and in the software, which is not an Antivirus. For example, CRC-checker - checker based on checksum - can be used not only to catch the virus. A variety of programs are dual behavior blockers, which analyze the behavior of other programs and upon detection of suspicious behavior blocking them. From the classic antivirus with anti-virus engine for recognizing and treating viruses, which were analyzed in the laboratory and which had been prescribed treatment algorithm, behavior blockers differ in that they treat the virus they can not because they do not know about. This property allows them to work interlocks with any virus, including the unknown. This is especially relevant today, as disseminators of viruses and antivirus programs use the same data channels, the Internet is. In this case, the anti-virus companies always take time out to get the virus, analyze it and write the appropriate therapeutic modules. Program of the group dual just help block the spread of the virus to the point, while the company will not write medical module.
