Rougue Antivirus 2010 false positive

[eok]

Seen on two systems: Windows XP 64, Windows 5.2.3790 Service Pack 2

Malwarebytes' Anti-Malware 1.46, Database version: 4818

We configure our start menus so that all Audio/Video apps are kept in a Start Menu folder called "AV". We discovered that Malwarebytes identifies the AV Startmenu folder and all its contents (subfolders and shorcuts) as infected with "Rouge Antivirus 2010". Kind of a shock, since we're pretty fastidious about security.

So, before we followed malwarebytes suggestion to blow away the dozens of entries in our "AV" Startmenu folder, we gave our systems a thorough analysis. We actually found no trace of Rouge Antivirus 2010 on our systems.

On a hunch, we renamed the "AV" Startmenu folder to "Audio_Video" and rescanned with Malwarebytes. Malwarebytes no longer listed anything as infected.

I suppose the reason for the false positives was the presence of a Startmenu folder named "AV". We could imagine that the presence of a folder/object named "AV" could be part of a fingerprint for Rouge Antivirus 2010 (eg: "AV" is often associated with "Anti-virus"). But, allowing malwarebytes to trigger on just the presence of an "AV" Startmenu folder seems kind of a stretch to us.

It would be helpful to have a scan log from when this problem occurred.
