svchost.exe (netsvcs) using a ton of CPU

My Toshiba laptop is extremely slow an I've found out that svchost.exe is using up 85-95% of available CPU (consitently running at 100%).  I've done full virus scan, in and out of safe mode, with Norton, Malwarebytes and Spybot with no threats found.  I installed Process Manager and all of the systems that are running on this instance of svchost seem to be typical functions like Windows Update and Themes.  Firefox can run ok, but Internet Explorer just freezes and everything is generally slow.  Any help would be appreciated.  Thanks!

Hi Jack,

-Did you make any changes to the computer prior to this issue?


svchost.exe (Service Host, or SvcHost) is a system process which hosts multiple Windows services. It is essential in the implementation of so-called shared service processes, where a number of services can share a process in order to reduce resource consumption. Sometimes viruses can spoof themselves as system files.
