The CPU usage on my Windows 7 desktop is 100%. I have used Process Explorer to determine an avp.exe file is responsible for 94- 98% of the usage. This file is supposedly from Kaspersky 2011 Anti virus. I attempted to end the process on task manager to see if the CPU usage would go back down, but received a message that access was denied. When the computer is first started it runs well and the CPU usage ranges from 40-50%, but after running a few minutes the CPU usage hits 100%. The computer slows down considerably and programs stop running. It takes in excess of 24 hours to run any spyware or virus scans and no threats have been found. Should I uninstall Kaspersky? Or could some other problem be causing the high CPU usage?

I'd definitely reinstall Kaspersky.

Maybe you didn't elevate Process Explorer (run as administrator).

If you do a Google Search for High CPU avp.exe, you will find this issue to be a common complaint from Kaspersky users especially at their own support forums. The Kaspersky Support Team usually asks that you post a GSI report created by their GetSystemInfo tool in a new topic so they can provide individual assistance.

Thank you for all of your suggestions. I tried to go to the Kaspersky support page and forum yesterday but the computer was running so slowly the page wouldn't open and I don't have Kaspersky on this computer thus no access to the forum. I will turn that computer back on and try to go to the Kaspersky site immediately before it starts running slowly and see what they recommend I do next.

You can try to suspend the process. Start Process Explorer (run as administrator), select avp.exe and suspend the process (right-click suspend).
This should make your computer fast enough to access the forum.
The process will remain suspended until you resume it or you restart your machine.

I went to Kaspersky and clicked on Support and a window came up suggesting I upgrade to the newest version. It took a few tries, but I was finally able to download Kaspersky 2012, and that seems to have solved the problem. The offending file has apparently gone away with Kaspersky 2011. Thank you again for the helpful suggestions. Computer problems are frustrating, but I pick up some new skills with each one I tackle.
