I am running Windows Home XP.

I am new to this game so I did not want to do anything (Spybot, HijackThis, AD-aware) before I posted this and had you look into it.

This is my wifes PC, and she started noticing that it was slowing down and ADs were popping up all over the place.

Thanks for any help.
