Task Monitor shows svchost.exe(netsvcs) using 90%-100% of CPU
Restarts if killed.
No new programs installed.
Win7 64bit SP1

MiniToolBox
Malwarebytes Anti-Malware
Malwarebytes Anti-Rootkit
rkill
Temp File Cleaner
AdwCleaner
Junkware Removal Tool
Sophos Free Virus Removal Tool

The above tools were all run and logs reported at the following lonk:
http://www.bleepingcomputer.com/forums/t/622966/computer-very-slow-100-cpu-usage/page-2

For whatever reason, I booted into safe mode to type this and killed svchost.exe(netsvcs) -- and CPU usage is back to normal and svchost.exe(netsvcs)did not restart.

Thanks for the reply.
While awaiting a response, I turned off Windows Update (to 'Never check for updates') and the problem appears to be solved. Should I still follow your instructions above?

Nothing malicious found on your logs. The fix I suggested is just a clean up of empty registry entries.
Your Call.

I would update the Java your version is vulnerable.

When all is done.

Check for the Microsoft updates on occasion.

If all is well.
