This antiviral program offers rock-solid protection for no financial commitment. AVG Anti-Virus Free Edition provides all the necessities, including a tool for scanning your hard drive and e-mail, as well as a real-time shield to prevent infections. 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 create 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. This app's interface can't be described as beautiful, yet it is mostly simple to navigate. Sure, you can plunk down a lot of cash for an antiviral application with more features, but AVG Anti-Virus Free Edition delivers the goods for free.
