Is a good product for keeping your computer safe from viruses, but is not as effective as it should be against spyware. While it has a good track record of keeping viruses off of computers using it, it also has significant issues with slowing down computers that it is protecting. Symantec has done a lot to fix the slow down issues by reducing the amount of system resources used, but they still need to do more work to make the product a contender in the modern antivirus market.

AVG - http://www.download.com/AVG-Anti-Virus-Free-Edition/3000-2239_4-10320142.html

This antivirus program offers rock-solid protection. By default, the application is set to search for new virus definitions daily, but you always can use the scheduling tool to change this. Should a virus create serious system problems, AVG creates a rescue disk to scan your computer in MS-DOS mode. The program doesn't tax your system when scanning or when running in the background and always proved effective in our tests. The new interface is much easier to navigate than in previous version, with tabbed navigation on the left assisting users in drilling down to the tools they need
