Repair an unbootable, virus-damaged PC with Avira AntiVir Rescue System. If a virus attack has affected your PC to the point where it will no longer start, then the Avira Rescue System may help restore normal operations. And if you think your PC is infected by something, but your regular antivirus tool can't find it, then this could be a useful way to get a second opinion. Booting from a separate CD means that stealthy malware like rootkits will find it more difficult to hide, and you'll have a much better chance of detecting and removing them.
It's easy to create the boot disc: just download the Rescue System executable, run it, place a blank CD in your drive and the program will burn the boot disc for you (no other burning software is required).
