remove virus causing explorer.exe to use 100% CPU

[jpattdc]

My explorer.exe keeps multiplying and using 100% of my CPU. I used malwarebytes in safe mode and got rid of everything it found. I used hijackthis and removed the bad studd. I used Kaspersky rescue10, booting up from my CD and cleaned my hard drive from 1 virus. I used AVG antivirus which told me my drive was clean. Yet something is causing my explorer.exe file to go crazy. Help, anyone.....

I have always refused to reply to these discussions unless I had a solution (i.e., don't reply unless you have solved it, don't answer a question with more questions). I have solved it - at least on my system.

malwarebytes found dozens of threats (minor and major) on my system that were not detected by Norton 360 or Norton Power Eraser. And now it continues to protect my system from certain malware when Norton does not. My system is also WAY faster than ever before.

I am impressed with malwarebytes.

jasn009, as I said in my post, Malwarebytes is great, "the gold standard" for removing mal/spyware. Norton is known to be highly ineffective against anything. All it has going for it is the brand name which has been around for so long. However, Malwarebytes doesn't detect everything, and doesn't claim to be a rootkit remover. In this case Kaspersky's TDSSKiller.exe (a free tool) removed the "bootkit." High CPU usage doesn't always mean a virus, sometimes it's a crashed process, or something running that is unexpected or shouldn't be.

Run TDSSKiller , it will remove malware that blocks other anti-malware softwares.Then Reboot your computer. This worked for me.

Thanks samtt; TDSskiller worked a treat, I have been sitting watching task manager while online waiting for he CPU % to explode but it's fine. PHEW a PC I cn now use; again thanks.

Darkhorse, I had the same exact problem which took me hours to finally find the solution. Try running kaspersky anti virus, even just the trial version. It should take care of the problem. I tried maybe 4-5 different anti-virus programs and none of them worked except kaspersky

I had a similar problem, high CPU and memory %'s, causing my computer to be slow and unresponsive. The free trial of Kaspersy's anti-virus program works like a charm. Thanks for the tip, HP was telling me I needed to do a system recovery.

Sad note to the end of the story (2 weeks later). Had a virus attack my computer and start deleting programs. I was forced to do a system recovery. Wish I had used the time Kaspersky's bought me to save my documents.

I had the same issue with my computer, i had downloaded some video from youtube and when i played those videos my cpu usage went to 100%, and whenever i went on those folder in which the videos got downloaded the cpu usage gets 100%, so i had deleted those videos completely from computer and the problem is solved. try and c if any such video, picture or movie u had downloaded maybe that's causing problem.
