Top 5 antivirus

1) McAfee VirusScan Plus
Antivirus, antispyware, and firewall are included in this 'mini-suite' from McAfee. An ideal candidate for those seeking robust protection without all the bloat of traditional Internet security suites.

2) BitDefender Professional Edition
Softwin's BitDefender Professional protects against viruses, spyware, and instant messaging threats, as well as offering firewall rules to block undesirable traffic and a privacy gateway to keep your identity and preferences private while surfing the Internet.

3) McAfee Internet Security

For those seeking a full blown Internet security suite, McAfee Internet Security offers traditional antivirus, firewall and antispyware complete with spam and phishing protection as well as backup utilities. McAfee's superb detection rates are near legendary.

4) Kaspersky Anti-Virus Personal
Kaspersky offers excellent antivirus protection, perhaps unsurpassed in its ability to recognize various compression algorithms and accurately detect infected files contained within the archives. However, their interface is rather convoluted and may be best suited to more advanced users. Should be used in conjunction with a firewall.

5) PC-cillin Internet Security Suite
Building on its solid antivirus capabilities, PC-cillin Internet Security Suite automatically checks for new virus updates every 3 hours and the spam prevention includes a whitelist, blacklist, and Bayesian filter - all at a price substantially lower than many other antivirus suites. If spyware is a problem, consider supplementing the spyware scanner in PC-cillin with either Windows Defender or CounterSpy.
