Anti-virus software is a kind of anti-malware software which protects a computer from viruses and sometimes also, Trojan horses, worms and other forms of malicious software (malware). Antivirus software protects a computer by comparing files and processes against signatures of known malicious software. If suspicious files are found it will delete or quarantine the malware[1] Antivirus software is important for both Windows and Mac users.[2] Two leading Internet security companies, Intego and Symantec, both sell dual protection antivirus programs, which protects Mac OS X and Windows from all known viruses.[3]

Many anti-virus companies offer both free and paid options. For some, the free versions are enough, but other find the more options and sometimes better protection of the paid plans worth the cost. Here are some popular anti-virus options.
