AV cant find viruses Tags: Security Virus CPUs Security Essentials Apps Last response: July 18, 2012 12:43 PM in Applications Share N11Ckk123472 July 17, 2012 12:18:46 AM I'm getting very high CPU usage on my pc (spikes from 40% to80-90% constantly) and I usually have no background processes so I was told that it is a virus. I tried malwarebytes and MS security essentials, and neither of them found a virus. Idk if this should be on CPU forum or this anti-virus forum so I'll try both. If anyone has any help/tips it would be appreciated.

The easiest way to fix this is remove the hard drive, attach it to a USB hard drive adapter, then scan it from a known good PC to remove the virus. | Report abuse Hawkeye22 Security Expert July 18, 2012 12:24:43 PM Use the task manager to look at your process list and find which process is using up all the CPU. | Report abuse N11Ckk123472 July 18, 2012 12:35:41 PM Atiutility and AtiGPU | Report abuse Hawkeye22 Security Expert July 18, 2012 12:43:27 PM I recommend uninstalling and reinstalling those. It may be a matter of just updating to the newest video drivers. | Report abuse Register or log in to remove Ask the community Publish Tom's Hardware>Forum>Applications>AV cant find viruses> Related ressources: ForumWindows xp av help I have a bug from windows AV and i cant even open the files o ForumViruses and their effect on gaming...
