I love spybot S&D, but I did have something hijack Spybot for several months. I did scan after scan with Spybot, Microsofts spyware detector, Pest Patrol, and Adaware and nothing found it. I even ran 2 sets of virus software.

I knew something was hijacking my system because every time I tried to update all of my spyware it would never remain updated. When I tried to update from S&D it would usually come up with a bad checksum. I could and did, for a while, update and scan every day to no avail, even with all of my spy software and my virus software.

Finally I downloaded the new version of Spybot 1.4 and its update from the website, and when I ran the spy check it found 17 spybots, and now my system runs perfectly fine now.
