For home and student use, we think Norton 360 represents the best value for ease of use, tools offered, and overall system performance. We recommend it over McAfee Total Protection and Microsoft Windows Live OneCare.

AVG

AVG Anti-Virus 8 is solid at finding and removing viruses and spyware as well as blocking Web threats, but could be lighter on system resources and provide more technical support options.

Mcafee

McAfee is a name brand product that does an excellent job at detecting and removing viruses. Their update process can be somewhat tedious and their support department needs to answer their emails in a more timely manner.

Kaspersky

Kaspersky is among the best antivirus software packages on the market today. It’s highly effective, has a great interface, and it’s easy on computer resources. Kaspersky is an excellent choice and was barely edged out by BitDefender, receiving the “TopTenREVIEWS Silver Award.”

Ad-Aware

Interface refinements make this the easiest-to-use Ad-Aware yet. Action button placement at the bottom of the pane might feel odd to those familiar with older versions, but the forced continuity between windows is a plus. Links to drill down to more information are easy to see, as is the Settings button. Overall, Ad-Aware continues to make improvements and seems to be unwilling to rest on its malware-removing laurels, but the free version is undeniably hamstrung.

zonealarm

ZoneAlarm Internet Security Suite 7 provides the perfect balance between best-of-breed security protection and ease of use, providing the home user with superior protection that's light on system resources.
