Another question: Can a virus be activated by a software everytime you use the software? Meaning, I downloaded some softwares from an online source...(its trusworthiness is now out of the question) and this is how I may have started this mess. Alcohol120% and Autocad and I think somewhere in the installation or something, all this went wrong. Now, after cleaning the pc to this point, I realize that both softwares still work fine. However, could the cleaning "clean out" the bugs in them, or would they be activated everytime I start up the softwares. I hope its not the latter cause I really need the cad to work with.

thanks again
