Below we have complied a comprehensive guide to antivirus packages out on the market today. We have used all of the listed packages personally and have in depth knowledge on them. The comments made on these packages are not through us but instead several different virus comparison web sites on the internet today.

Package	Price	Compatibility	Comment
NOD32 By ESET	£26.99 Direct	Windows 2000, XP (32 and 64-bit editions), Vista (32 and 64-bit editions)	Computer experts say NOD32 offers great protection, no system drain and no software conflicts. User satisfaction with NOD32 is much higher than with any other antivirus program. It consistently earns top ratings, while competitors earn average ratings or worse
Kaspersky Anti Virus	£24.00 Direct	Windows 2000 Professional (Service Pack 4 or higher), XP Home Edition (Service Pack 2 or Higher), XP, Vista, Vista x64	Kaspersky has more software conflicts and issues than the average antivirus program. Yet program users express a much higher level of satisfaction with Kaspersky antivirus software than with Norton or McAfee programs
AVG Free Edition	£0.00 Direct	Windows 98, Me, NT, 2000, XP, Vista	Professional reviewers conclude that AVG Anti-Virus Free Edition is the best of the free antivirus programs. That program fares poorly when compared with Kaspersky and NOD32, among others. AVG and other free programs offer much less user control than commercial programs
Norton AV By Symantec	£39.99 PCWorld	Windows XP, Vista	Norton continues to be the best selling antivirus program, and reviews say it's excellent at detecting viruses. However, half of all users complain that Norton AntiVirus slows their computer to a crawl, and that it conflicts with other software. Only a quarter of users give the program a high rating. Users also dislike the high level of control Norton exercises over a system
Panda Internet Security 2008	£19.99 PCWorld	Windows 2000, XP (32 and 64-bit editions), Vista (32 and 64-bit editions)	Security suites bundle antivirus and anti-spyware software, a firewall and other components into a single program. Reviews say the secondary features (such as spam prevention) of Panda Internet Security 2008 aren't very good, but it excels at its primary tasks
