Disabling it in msconfig should stop it from loading after you next restart your pc although a few more sophisticated ones might get round it

Also try searching for some more information about it using Google. You should be able to find out which files/registry keys it creates and delete them manually, basically this is usually all the Antispyware software does anyway

Hijackthis can help do that to.

Its amazing how much stuff the antispyware software can miss!!
