Ian Brown shows us how to use Avast to remove viruses from your computer. First, go to Avast.com and download their new and free edition of their virus protection. After you have installed this program, you will receive an email with your product key to access the program. Now, change the settings on the program so it scans your computer at least once a day for viruses. Now, reboot your computer to save settings and scan your computer automatically for viruses. When you see a blue screen with questions, don't be alarmed, it's just doing a scan for viruses throughout your system before it starts up again!
