Thank you very much, all of you. With your advise i helped fix the problem. What i did was i wento n google and researched it, and was finding nothing at first, but then out of nowhere a website told me exactly what it was (just like someone above said), it was a aplore worm or something like that. I found the registry key and got rid of it. Then i simply used housecall to finalize everything.
I had used housecall before, however because of the fact that it kept restarting when i restarted my cpu, it remained there for a while. I had to get rid of this worm in the registry first. Thanks everyone
