This is a generic detection for the Brontok Worm. The Brontok worm has been around since 2005 in one form or another. Most variants have the ability to disable security software and participate in DDOS attacks.
Worm.Parite is a polymorphic file infector. It is capable of infecting all executable files on local and shared network drives.
Any infected machine should be taken out of the network immediately. If possible, a backup of important, non-executable files should be made.
Malwarebytes can remove infected files, but it can not repair them. The infected system should be reformatted and any network drives it is connected to should be scanned else infected files can be copied to or used by other systems that have access to these drives.
