S.D.
I'm so glad when I read other mom's suggestions before I put mine in. I learn so much! I'd definitely suggest you download the free anti-spyware program that the others recommended. I just had to remove malware from my computer. It must have gotten loaded from something my kids downloaded without my permission. Ironically, it was called "Malware-Alarm" and it just opened and started scanning files on it's own, mascarading as a real demonstration version of a legitimate program. I knew better, but those things can be tricky to get rid of. And I have anti-spyware software! I had to go to Microsoft's site for removal instructions.
