AVG detected bms.exe as a threat

Black Mesa Archive In-game Issues
#1

I was playing BM, saved my game and quit.
When i saw my desktop, AVG opened a window saying:
[attach=4000,none,503][/attach]

I clicked on more info, it opened a website saying more about the threat.
Type Unknown it said.I added the executable as an exception in the AVG.

It is probably nothing, but i guess it’s for the best you
guys have this in case of future problems like these.
