You're best asking MBAM questions in their forum: http://www.malwarebytes.org/forums/
However you may want to post a Hijackthis log as well so they can analyse what's going on and they have a special area for that.
Do not post Hijackthis logs here, we can't help with those!
Look for the 'False Positives' section.
Alright. Thanx for the info.
Good luck. ;-)
