Yesterday my brother did something really dumb. He wanted to get the Opera browser and somehow he managed to get my PC a virus. At first, I turned my pc on a few minutes passed then I got a blue screen. After I rebooted a strange acs.exe was taking up all my cpu and crashing it. I performed a system restore but it is still here and I cannot end its process but it does not crash me at the moment. I tried running a Malwarebytes scan and a few minutes pass then my pc completely shuts off and on the reboot it says overclocking failed. Please help me D:
