Windows 7: virus possibly related to svchost.exe

Any further suggestions to continue correcting the system? I didn't mean for the last post to appear as solved, just that I think I may be making progress.

svchost high usage

I had a similar issue once. The solution that worked for me was:

Downloaded and installed Process Hacker:

Overview - Process Hacker

Downloaded and installed RAMmap:

RAMMap

Used RAMmap to get the PID of the troublesome svchost process. Used Process Hacker to view details and checked services associated with the svchost process. Found that windows update service was listed in the services tab for that process. Stopped the windows update service and usage returned to normal levels.

The cause was a failed windows update and repairing windows updates, (cleaning windows updates temp files and windows updates history then running the windows updates repair hotfix) followed by a reboot did the trick.

Svchost.exe runs background computer processes like services, which do not have a user interface.

You do not need to download any additional tools, though.

Please go to a Command Prompt:
Start > Programs > Accessories right-click Command Prompt
Select: Run as Administrator

Using the mouse, copy the following text inside the code box:
Code:
TASKLIST /SVC /FI "IMAGENAME EQ SVCHOST.EXE"
Paste the above at the blinking cursor of the Command Prompt
Press: Enter

To obtain and post the results, go to the small icon on the top left of the Command Prompt frame
Go to Edit > Select All
Then, Edit > Copy

The info is now copied to the clipboard.

Paste the info to your next post.

Close out of the Command Prompt by typing: exit

I didn't download or listen to any advice the other guy posted. A new member with a handful of posts isn't one to trust in my opinion. He might know what he is talking about but I have done most of my exchanges with these gurus. At first I thought it was something with the svchost process (random google search), but after running everything, you didn't make any reference to it, so I think the thread is incorrectly titled. New title... There is something wrong with my computer, just running too slow, almost overnight, and I don't know what it is or what caused it. One thing I have noticed though is that as soon as I start task manager, CPU usage is over 70%, but then drops to zero. This is with no open applications, just background processes. Is that normal? To me it seems almost like something is hiding it.

Hmmmm...

This is a tough one.

Let's see if we can pinpoint a cause.
The following log contains info about Plug and Play devices and driver installations.

Please go to Start, and in the Search programs and files box above it, copy/paste the following text inside the code box:

Code:
%WINDIR%\inf\setupapi.dev.log
In the results that appear above, double-click: setupapi.dev
Notepad opens, but, give it a few seconds to load the info.

When done, please provide the setupapi.dev.log info in your reply.

I'm back out of town and away from my desktop for a couple days, but I will run it and get back to you on Wednesday. As always, thanks for the advice.

I got back early in advance of the storm. The setupapi.dev was run but the log cannot be attached. It is too large, about 9.6 MB. Any suggestions? Split and upload in parts? Thanks.
