Everytime you run it.

Spybot has only caught about 10 more minor things that Adaware didn't catch for me. But when I run Spybot first Adaware gets quite a bit more than it after Spybot runs.

I got a machine that was SOOOO bad, that WinXP tried to auto-rollback out of an auto-install of one worm and while another worm was deleting checkpoints for rollbacks at the same time. While she also tried to install Symantec's Norton Anti-Virus... Ouch.

Let us just say, that WindowsXP doesn't do too good at 320x200 resolution, and no an unknown PCI BUS and quite a few other things.

Needless to say, it was not beyond my skill, but dam that was a pain. She had her Business records on the machine without any backups. Again, I made a backup of all her stuff on CD-R, on her machine.

All I can say is: Wow, I taint never seen that many "objects found"
