I have an IBM ThinkPad Z61m (ancient, I know) that I believe is pretty virus-ed up. Can anyone recommend a good program that I can burn onto a DVD or CD-R and run on my machine? I've been getting a ton of blue screens trying to boot up lately and have various different anti-virus programs going (Avast, Security Essentials, etc.) which keep quarantining various processes but I'd like to just clean everything up (delete programs, fix registry, etc).
Would restoring it back to factory settings via the blue Thinkvantage button fix the problem? I realize I would lose all of my personal data but I am currently trying to get it backed up on my external HDD.
