Ive tried two times now reinstalling and each time I download the new patch AVG flags it as a Win32/Heur Virus and I can go back and copy and paste the original EXE file from the disc. The game still runs perfect but when I go to play multiplayer there are never any servers to be found. The only thing I can think is because the exe file is the original non patched exe that I am not being able to see servers that are more than likely have the new patch. Anyone else having similar problems? any suggestions?

its not actually a virus its a message that indicates that the file has virus like characteristics its just a false positive crytek already confirmed it.

With avg you have to go to your resident shield and add the patched crysis 2 exe to the exception list it will work then i think the so called virus is a false positive let me know if it helps.

Thank you two for the help you were right on. Works perfectly now thanks again for the info.
