Game guard is an anti-cheating application used with MMORPGs . I have read that such applications acts as rootkit over the pc.
And that control over your system could have been flagged as well.
GameGuardian acts as type of inter-process communication proxy, it can stop applications, hide process information from the user,
and I believe also has a key-logger. (* info credits go to security.stackexchange.com’s Peleus)
All in all probably a false positive i.m.h.o. and should be reported as such, and SHPsoBBw.exe could be excluded in the mean time.
Thanks for the info Polonus,
