I have been having this problem for weeks now, and have looked on many different forums for good/bad processes running. I have turned off the automatic update feature, removed (or so I thought) some bigger programs, installed and ran CCleaner after uninstalling RegCure, installed and ran avast! after uninstalling the Shield Deluxe. This site has many processes listed that are labelled as bad, etc., and some labelled as good, and some labelled as good and bad. From the task manager I can't tell which is what. I also have read that you should not just have one AV program, but a few, but don't know which other ones to install (have read good and bad on all of them from different forums). Very frustrating. CPU usage isn't always spiked, well right now it is, but seems to go up and down at differing intervals. The mouse will start and stop and start again, any video will start and stop, and yesterday, my CD drive just started opening up once in a while for no apparent reason,though it hasn't done it today. Started an avast! thorough scan last night before bed and still at 66%. I will try and copy and paste a list of processes running. Well, can't do that. So I'll go this route. Which column should I be looking at as most important in my task manager as far as using the most CPU (memory usage, peak mem usage, i/o reads, i/o writes, etc.)?

Well it's actually not recommended that you have more than one antivirus program because they can conflict with one another. I would get rid of all but one and then install Malwarebytes and SUPERAntiSpyware. Run the scans with those to make sure you don't have any malware or spyware on the computer.

Adding the anti-spy and anti-mal found hundreds of files. I still have a lot of processes running, to include 8-9 svchost.exe. I've ran the CCCleaner and tried to dump what I knew was bad out of the registry, but a alot of it has come back. Even if I remove the process on some, they come right back as soon as I do it. Thing is, I've read on this forum that some of the scvhost.exe's are bad, but I can't tel from just the list of processes one from the other. How do I find the complete file name or directory for the process so I can tell the difference? What do I do with those I can't remove with CCCleaner?

Have you tried updating and running your antivirus program yet? If not, I would do that and remove whatever it may find.

I found this as well......

"What is svchost.exe And Why Is It Running?

According to Microsoft: a svchost.exe is a generic host process name for services that run from dynamic-link libraries. Could we have that in english please?

Some time ago, Microsoft started moving all of the functionality from internal Windows services into .dll files instead of .exe files. From a programming perspective this makes more sense for reusability… but the problem is that you can't launch a .dll file directly from Windows, it has to be loaded up from a running executable (.exe). Thus the svchost.exe process was born.

Why Are There So Many svchost.exes Running?

If you've ever taken a look at the Services section in control panel you might notice that there are a Lot of services required by Windows. If every single service ran under a single svchost.exe instance, a failure in one might bring down all of Windows¦ so they are separated out.

Those services are organized into logical groups, and then a single svchost.exe instance is created for each group. For instance, one svchost.exe instance runs the 3 services related to the firewall. Another svchost.exe instance might run all the services related to the user interface, and so on.

So What Can I Do About It?

You can trim down unneeded services by disabling or stopping the services that don't absolutely need to be running. Additionally, if you are noticing very heavy CPU usage on a single svchost.exe instance you can restart the services running under that instance.

The biggest problem is identifying what services are being run on a particular svchost.exe instance's¦ we'll cover that below.

If you are curious what we're talking about, just open up Task Manager and check the Show processes from all users box:

Using Process Explorer in Vista or XP

You can use the excellent Process Explorer utility from Microsoft/Sysinternals to see what services are running as a part of a svchost.exe process."
