SVChost.exe - k netsvcs has crippled my machine like no malwaer ever has. From what I can tell, this has something to do with Windows Update.
Nothing else unsual is running. There is no malware involved. And all updaes are installed Except I cannot update .net. I get the following error message:
"Microsoft .NET Framework 3.5 Service Pack 1 and .NET Framework 3.5 Family Update for .NET versions 2.0 through 3.5 (KB951847) x86"
What can I do? I am frustrated.

Thanks for the help! I followed Joel's advise above & it SEEMS to have resolved the problem. I say SEEMS, because I have seen the problem apparently resolved, only to resume again after a few days. Updated Malwarebytes showed no infection doing a deep scan.
I will be back if proble returns.... for now, issue resolved!
I only ask because of a funky bug that seems tied to (perhaps an older version of) the nVidia drivers, for the 650i chipset, that caused registry corruption that ultimately caused issues such as you describe.
More details at:
Excessive CPU usage-SVCHOST: 650i chipset
The corruption appeared in the [HKLM\SYSTEM\CurrentControlSet\Control\Network] section of the registry. It is potentially possible to repair, described here. Of course, you would want to first inspect to determine if the problem was the same / similar, in the first place. This issue with the nVidia 650i driver package happened over 2 years ago, it seems, so one would hope that it would be corrected in newer packages/drivers. Still, your description reminded me of the concern, so I thought I would mention it.
Any chance you're able to use System Restore to restore the system to a point in time prior to the manifestation of the behavior? Did anything in particular seem to trigger the behavior? Are there any noteworthy events in the event logs (Event Viewer)?
My system restore points were all lost when I had to repair a Virtual Disk malfunction a while ago. So, no, that is not an option.
AnVir points out that there are several svchost.exe lines working. The one that is causing all the high CPU usage is:
SVChost.exe - k netsvcs
Any idea why this one is causing high CPU usage?
If I knew how to on this forum, I could send a "Hijack this" log.
Click here to download HJTsetup.exe:
Click on "Download Now"
Save HJTsetup.exe to your desktop.
Double click on the HJTsetup.exe icon on your desktop.
By default it will install to C:\Program Files\Hijack This.
Continue to click Next in the setup dialogue boxes until you get to the Select Addition Tasks dialogue.
Put a check by Create a desktop icon then click Next again.
Continue to follow the rest of the prompts from there.
At the final dialogue box click Finish and it will launch Hijack This.
Click on the Do a system scan and save a log file button. It will scan and then ask you to save the log.
Click Save to save the log file and then the log will open in notepad.
Click on "Edit > Select All" then click on "Edit > Copy" to copy the entire contents of the log.
Come back here to this thread and Paste the log in your next reply.
DO NOT have Hijack This fix anything yet. Most of what it finds will be harmless or even required.
DO NOT install or uninstall anything or otherwise make changes to your computer until we are finished with this process.
