Antivirus (anti-virus) software are computer programs used to detect, remove and prevent all sort of malicious software that can affect a computer system, threats like computer viruses, keyloggers, backdoors, rootkits, trojan horses, worms, adwares and spywares.
Free antivirus as download can help in this task, as they have features similar to any commercial product these days. The work of this type of program is based on signature detection: searching for known patterns of data within executable code of suspicious software.
The use of a antivirus free download can have drawbacks also, as antivirus software can impair a computer performance due to time taken to scan suspicious items, and can be little confusing for inexperienced user.
But they are a must for any network or internet connected computer, as according to an security survey, major businesses deal with a $12 million lose annually due to virus incidents.
