Running game hack-tool detected (10501)

Running game hack-tool detected (10501) it comes up every time i start the game it was fine yesterday, I am not using any hacks, and i don't have any on My PC at all. Help?

Thanks

well you must've dl some along the way. I had the same error message too. it might be some kind of virus because it is constantly in use. to delete, just go to local disk --> windows --> system32 --> and delete pnkbsterA or something like that appearing on the hack detected msg. If you can't delete it if its being used, just end the task in processes and it should be gone! hope that helps....

Ah it deleting pnkbsterA did not help, but i have never used hacks on this PC i got it about a month ago and played fine to now
