I am suffering from a similar problem too. In my case I have noticed that the multiple copie of the svchost are always changing their CPU usage but they combined altogether take up all my CPU usage capacity. I suspected some virus but at least McAfee is not able to detect anything (using the .DAT file updated on April 21, 2009).

Another thing is that this is causing the processor of my laptop (Dell inspiron 1300)to heatup and usually when I reboot the hardware gives a heatup warning. The system however is working fine in safe mode. No excess CPU usage and heatup of processor.

One thing I tried yesterday that temporarily solved the problem yesterday (but the problem is back again today). I changed a lot of services configurations closing all the services that I do not need all the time (including windows auto update) and then I ran disk defragmenter. This all I did in safe mode. Yesterday after I finished this procedure, everything returned to normal. Today as I booted the machine the problem is back and now I am back in safe mode trying to solve the problem.

Please anybody help.

I already disabled auto update service. Nothing. I think the auto-update and svchost problem is an old problem already reported and properly patched in year 2006 or 2007. But I have tried this solution and nothing.

The thing confusing me is that when I go into safe mode run anti-virus and defrag the disk, it usually wirks fine on the next normal boot. But with further rebooting the problem comes up again.

I am running into the same issue as you guys. From trial and error i noticed this being a problem when I was accessing the internet. So, recently, I decided to not use Internet Explorer and use Firefox instead because I heard IE takes up lot more resources than Firefox.

I've only done this for a day and it seems to be working so far......

What virus software did you use? i have norton's NAV and no viruses found.....

Check the spelling - is it svchost or scvhost? If it's the latter, it's a virus. In case your computer is NOT infected, check out an article here: http://www.fileinspect.com/fileinfo/svchost-exe/. It helped me when I had a similar problem.
