Client-side error

I have several computers that are constantly throwing up the same error in client-side events. This has happened before the May 6th debacle but right now it is the only event being generated since the false-positive ordeal. Has anyone seen this before? I know several files were deleted from computers due to the false positives so it may be related.

Event ID = 3254789906
Description = Internal error has occurred in module adnmComun.dll, function CClient::Popup Thread()
