I ran AVG and it came up with 12 boot sector virus' so I fdisked it and ran AVG again and the virus' remained. Are there some programs that will help me.
Twelve boot sector viruses? Wow. I'm surprised your machine can boot. Kudos to the virus writers for that one. Are you sure you're running the latest definitions? Do you have another A/V scanner (I think F-Prot lets you download their DOS scaner for free?) you can use to confirm this?
If you're not worried about saving data (and it doesn't seem like you are), I'd pop into your BIOS and do a low-level format. If your BIOS doesn't have this option, Google will show you where to go. Once you're done, and you know you've booted off a clean medium (this is *very* important), your HD should be clean. If it's not, there's something funky going on.
