tobad it dosn't work for real infections..
You mean the ones where you can't access your Task Manager, your Command Prompt, edit your registry, or install or run a program designed to fix the problem?
Yeah, the solution for one of those is to reformat, which a different friend of mine recently encountered. Everything was also disabled in Safe Mode, too, so she had no way of fixing it. Luckily, her brother got someone to check it out, struggle with it for about three hours, and then reformat it.
If you already have a program installed, you rename the executable and run the program. If that still doesn't work, nothing Microsoft produces will fix it...unless it's an install disc and not just a backup or upgrade disc.
