Hi Astinius,

I Just checked inside of the MBAM database and we have defs for the BHO file,the BHO CLSID and for that particular rogue variant.

We should be hitting that so would look for another possibilty as why they are not being hit.

Usually at this point it is another installed piece of malware that is blocking MBAM from operating normaly or the old chestnut of using an old version of the database(yes some folks dont upload to most recent DB or malware blocks the software from updating).

But for the record fully functioning MBAM with current database will unload this rogue install and its BHO helper :D

astinius,

I am greatful for the data etc but know what is already in our DB

If the DB's were updated then there most be someother malware present that is interfering with the MBAM scanning and parsing against its database.

Have you checked the pc for rootkit activity or other active malware ?

I will double check with the tech who provided the information to make sure he has reported all of the correct details.

Thanks,
