"Antivirus" redirects here. For antiviral medication, see antiviral drug.

Аntivirus software consists of computer programs that attempt to identify, thwart and eliminate computer viruses and other malicious software (malware).

Аntivirus software typically uses two different techniques to accomplish this:

Examining (scanning) files to look for known viruses matching definitions in a virus dictionaryIdentifying suspicious behavior from any computer program which might indicate infection. Such analysis may include data captures, port monitoring and other methods. Test your computer's exposure to online security threats and learn how to make your computer more secure.

Most commercial antivirus software uses both of these approaches, with an emphasis on the virus dictionary approach.

Historically, the term antivirus has also been used for benign computer viruses that spread and combated malicious viruses. This was common on the Amiga computer platform.

If a piece of code in the file matches any virus identified in the dictionary, then the antivirus software can take one of the following actions:

attempt to repair the file by removing the virus itself from the filequarantine the file (such that the file remains inaccessible to other programs and its virus can no longer spread)delete the infected file

To achieve consistent success in the medium and long term, the virus dictionary approach requires periodic (generally online) downloads of updated virus dictionary entries. BitDefender Free Online Virus Scan.
