It's the nature of the beast/spyware. Different programs use different engines, and search for different problems.
I run AdAware, Spybot S&D, Spyware Blaster, CWShredder, and the MS Beta.
Be careful what you use, some spyware programs contain spyware.
Good luck,

I ran Spybot S&D and it found no spyware.
I ran MicrosoftSpyware Beta 1 and it found no spyware.
I ran Spyware Doctor and it found 215 spyware threats.
I don't quite understand that. I've always kinda depended on Spybot S&D. How could it miss all that?
Thanks for any info.
