I have a relatively new windows 7 desktop and I installed Ad-Aware the latest edition of the free software. Mistake. I also installed Spybot. I noticed that all of a sudden, I could not control the computer. It would go to different sites, even opening Internet Explorer and closing it. I thought it was a virus. I first ran Microsoft Security Essentials. It found nothing. Then I ran Ad-Aware, and it found nothing. Finally I ran Spybot, and it found nothing. I tried System Restore, and restored it to a previous date, and that did not help. The computer was out of control. I also noticed that Ad-Aware kept automatically opening and closing. Finally after about 8 hours, I decided to delete Ad-Aware. Bingo, that was the problem. After I deleted Ad-Aware the computer worked perfectly. To be on the safe side, I also deleted Spybot. Let the users of Ad-Aware be aware.
