Hit the Cntrl-Alt-Delete keys at the same time to bring up the Windows Task Manager. Click on the Processes tab and see what process is using the CPU time. Report back what you find.
You say that none of them are using unusual amounts of memory, but your question was about CPU usage. Are any of them using a large percentage of CPU time?
A little more information about your system. What is the OS (it sounds like XP), how much RAM, Processor make and speed. For example if you are running an Intel Celeron with 400 MHz and 128 megs of RAM or less with Win XP - a scanner and most anything else is going to bring the system to its knees.
If your system has plenty of hardware for the task - then it sounds like your program install altered drivers and settings leading to the hogging problem. The system restore only brought you back to a prior point and may have only confused things by using old settings with new drivers if they did not get cleaned out. Win XP has a hardware driver roll back feature that you may want to try. Also check your hardware device manager and see if there are any hardware devices that are showing a conflict or problem. Also try running the system info feature in XP by pressing windows key "r" and typing and msinfo32, OK. Under components click on problem devices and see if there is anything showing.
I am not impressed with Microsofts System Restore. I have had only limited success with it and have learned to use it only as a last ditch effort to try anything before clearing the drive completely and reloading Windows. System restore backs up some settings and drivers and seems to ignore others. I advocate partitioning and imaging the entire drive for a quick and easy restore when something bad happens.
I'm running on 256 with 1200 mhz, system processing has never been an issue. There are 3 using about 15 kb, even though I shut them all down the computer still persisted in it's lagged state.
Sounds like a difficult one. I see that there as not been many other suggestions.
Provided you still have the problem and have not re-installed your OS...
You may next want to try a selective startup by using XP's System Configuration Utility. Do this by pressing win-key R and then type msconfig. Go to Startup Tab and uncheck everything then restart. This will disable most startup apps including firewall and antivirus if you have them. See how the system performs. If it seems to run OK go back into msconfig and check one item and restart. Keep doing this until you find a program that slows the system a lot as you describe.
If none of this works re-run msconfig and from the "general" tab select the disagnostic startup and reboot. This should start your with basic necessary starting apps.
If none of this works I believe my first impression may be correct and that the scanner install, uninstall, system restore roll back altered your settings and what it now thinks your system should have for drivers, files, and programs. Before you reload your OS try unistalling and reinstalling other programs you already have. Such as antivirus, games, etc., file and driver updates you may have obtained from Dell and Microsoft updates since that restore point if you can remember. Otherwise rather than spending days trying to figure out what went wrong when, backup your data and reload the OS.
this might be a little late, but check for a service called svchost.exe, running as a local service, end task that service. i have that problem few times a day, i cannot get the service not to restart itself.
i am running ad-ware very often and i ran cwshredder as well. it said svchost32 is not on my system, although the svchost service is still starting up.
i have reinstalled windows a few times already, and i had the same problem on this specific machine a few times. i have replaced almost all my hardware already as well, and i can still not get rid of it.
You have some malware, svchost is a known problem..
Follow the link below and use the malware section to try to remove with spybot & ad-aware, and the cwshredder.
I don't believe they will remove this one which is pretty recent. But they will remove any others before you move on to spywareinfo.com, all information is on my website on how to proceed.
As a safety issue do backup all of your data while you can.
I had the same problem on an XP pro system running 100% CPU.
I killed the process csrss.exe with me as the owner and the CPU went down to 5%. There are two csrss processes, you can only stop the one that is owned by the user logged on. The other is owned by system ad you can not stop this one.
I still dont know why this has come up recently or what software caused it, it is only a work around. If anyone knows why this is so, please share with others.

When I had this 2 weeks ago, it turned out I had just picked up 4 viruses and 2 worms. It got so bad I formatted and reinstalled.

Do a search on this link for svchost, and read the several lines of different virus that use that name.
http://www.pacs-portal.co.uk/startup_pages/startup_s.php
In the first one it has a link to describe the true MS file of that name. The location of the file will tell you which one you have, MS or other.

I killed the process csrss.exe with me as the owner and the CPU went down to 5%. There are two csrss processes, you can only stop the one that is owned by the user logged on. The other is owned by system ad you can not stop this one.
