What is the best computer protection package such as norton or McAfee?computer virus

I have found that freeware security and utility applications, when chosen after careful research and used in tested combinations, can provide protection matching or exceeding that provided by commercial suites. The problem with most of the suites isn't the antivirus protection, it's that their firewalls range from middling to lousy. McAfee provides good virus protection, but if you look at the firewall's performance on the independent testing site matousec (http://www.matousec.com ) it does NOT provide effective outbound firewall protection, and it's spyware protection is also not very effective. Meanwhile, there are several good free antivirus applications that are certified by VB100 and/or ICSA that provide protection at the same level as the commercial programs.

If you need freeware security applications, you can choose from the following:

firewall: (listed in order of preference)

Comodo (http://www.comodo.com ), or

PC Tools (http://www.pctools.com/firewall )

Comodo recently released version 3.0 of its firewall, which adds an intrusion prevention component that's very effective, though it does take time for it to learn your system, and requires some ongoing attention by the user to make sure programs don't get improperly blocked. Comodo is one of the strongest firewalls available, freeware or commercial, according to the independent testing site matousec.com.
