KF Need help with a issue.

Today I was going to play Killing Floor, and I started it up normally, however, when I went to the server browser, the game froze. So I did Ctrl-alt-del, opened task manager, and for some reason, my AVG anti-virus had detected a threat of some sort.



Apparently the Identity Protection had detected this:



"General behavioral detection, C:\Program Files (x86)\Steam\steamapps\common\KillingFloor\System\K illingFloor.exe"



I sort of got a little freaked out at first, and like an Idiot, I contained/secured it. But now I'm afraid to restart my PC, because it just may straight up remove the .exe for good, I tried to get it out by allowing it, but its not working.



So basically, it detected something wrong with my Killingfloor.exe. I have never had this issue, nor any conflicting issue between the two in the past. I have owned both AVG and KF for over two years.



Also:



Havn't added any workshop content in past 5 months, so it cannot be some malicious workshop item.

Never occured before, mentioned above.

I allowed the threat after I secured it, to see if it would fix, which is the Killingfloor.exe, but it didn't return to the System folder.







Heres a picture.







I'm not sure if I should call AVG yet, and act foolish attempting to explain what Steam is, and the game, etc (Assuming most of the employees don't know what that all is.)



If I have to uninstall and reinstall my KF, I wouldn't really mind, but I would atleast like to know why this happened.





So if anyone could help me out here, I would appreciate it.



Thanks.



Also if you need any more details, just ask.
