I have a Compaq computer which is almost 2 years old...anyways it keeps freezing, I get pop-ups when I'm online and it is really slow. I called several local computer repair companys and they say it is probably a virus or spyware. But they want to charge 95$ or more to fix it. Can anyone tell me if this is probably what it is? And if so, is there something I can do myself? I am pretty advanced when it comes to computers

(i guess just not that advanced lol) so I feel I could probably do it if I know what I have to look for and do. Please if anyone can help me out!! I will try anything. THANKS IN ADVANCE!
