Antivirus software is a term used to describe a computer program that attempts to identify, neutralize or eliminate malicious software. This type of software is so named because the earliest examples were designed exclusively to combat computer viruses; however most modern antivirus software is now designed to combat a wide range of threats, including worms, phishing attacks, rootkits, trojan horses and other malware.

If you want a clean, mean piece of anti-virus software that does just one thing — protect against viruses — you’ll want this program.
t has a small footprint, and doesn’t take up much system resources. It will scan your entire hard disk at once for viruses and spyware, or can scan individual files and folders.
