How do I completely clean my computer from viruses?

November 27, 2009

I dont want to download any programs or buy anymore program, they dont work. Ive tried Norton, Trend Micro, spy-bot and ad-aware. Nothings worked. Not one bit. Can I completely clean my computer like reformating it. Just completely clean it, like starting from a clean slate or something?
btw i dont know they exact names of the viruses. My computer says they are trojans, backdoors, etc.
What is formatting? I have never heard of it.

i’m using windows vista & its very slow especially when i using the internet…need help how to speed up my pc?
