I am looking for help, in the last 1-2 weeks my computer CPU will spike to 100% several times a day leaving my computer unusable for about 5-7 minutes. After that the processor goes back to normal.

I am current on all MS updates. I am running AVG and did a full system scan. I installed SpyBot and it still happens.
I am running Vista Business, SP2.

Any help would be appreciated.

Can you see what program is using up all your CPU usage? When it spikes to 100%, open task manager and sort the processes by CPU usage.

Sometimes it is iexplore.exe (when watching videos online), other times it is System, and other times it is System Idle Process.

System Idle Process you want to have 99% CPU usage as it means the systems isn't stressed. Internet Explorer can use quite a bit of CPU usage when watching videos, playing online games, etc. Could you do this for me please, open task manager (sorted so the highest CPU usage is at the top), then open Internet Explorer. Now check to see if Svchost.exe is using 99% of your CPU.

I noticed a pattern where my cpu only spikes when browsing the internet, and further noticed it only happing on pages with Flash player such as videos/games. After searching I've discovered other users have this issue and it seems to be a recent update issue with Adobe and their flash player. I don't have it fixed yet but can consistently reproduce the problem by opening a web page with flash embedded.

I am thinking now that I am not infected. Thanks for you help anyways.
