AVG We are also aware that this incident has negatively affected our rating on CNET Download.com and other portals. We would appreciate if a few of our users would set the record straight.
An AVG database update this morning (December 24, 2010) incorrectly detects two DLL files (mbamcore.dll and mbamnet.dll) in Malwarebytes' Anti-Malware 1.50.1 as trojans.
If you use AVG antivirus and get these detections, ignore them. Update your AVG definitions; hopefully it will be fixed soon.
If you have already quarantined the Malwarebytes' Anti-Malware files using AVG (sent them to the Virus Vault), you can fix this as follows:
1. Set Exclusions within AVG
Exclude the Malwarebytes' Anti-Malware program files directory (usually C:\Program Files\Malwarebytes' Anti-Malware, or C:\Program Files (x86)\Malwarebytes' Anti-Malware on x64 operating systems) from AVG.
Precise instructions for how to do this for several versions of AVG may be found here.
2. Restore the Malwarebytes DLLs from the AVG Virus Vault
Step 1: Start AVG
Step 2: Click History -> Virus Vault
Step 3: Select mbamnet.dll and click Restore. Then do the same for mbamcore.dll.
Malwarebytes' Anti-Malware should now function as normal.
