Additionally, search add/remove programs to uninstall any applications associated with the above entries. After successful uninstalls, search program files to ensure all files associated with the applications were removed.

The following entry is not related to malware/spyware. If you do not recognize the application search add/remove to uninstall. Also, this app has no need to auto-start with windows. It can be disabled using  msconfig.

O23 - Service: RGService - Unknown owner - C:\Program Files\RadioGet\RGService.exe

The below entry could very well be one of your issues with the high cpu usage. While back-up monitoring often comes in handy, these applications run in the background using unnecessary processes. I recommend you disable this feature from start-up and perhaps manually run it periodically. This is especially true when major changes are made to your personal files.

O23 - Service: GFI Backup 2009 - Home Edition Attendant Service (GFIBckHAtt) - GFI Software Ltd. - C:\PROGRA~1\GFI Backup 2009 - Home Edition\GFIHInst.exe

Again, the below entry is safe, but has no need to start-up with windows.

O23 - Service: SMServer - SMServer - C:\WINDOWS\system32\snmvtsvc.exe

After completion of the Malwarebytes scan, Create a new restore point. Run the system to see if the problem is resolved. If you find it is solved, delete all restore points and create a new one. post your results for future assistance.

Thanks, Joel

Sometimes deciding which battle to fight is the toughest battle of all….. Please visit my website @ http://repairbotsonline.weebly.com/

The "Process Explorer" technique can potentially be used to get more information about what service in the netsvcs instance of svchost is responsible for the CPU consumption.  Once that detail in known, more specific steps can be taken to attempt to address the problem.  Another option would be to use Process Explorer to selectively stop services that are running in the netsvcs instance of svchost.  If you stop a service, and the CPU usage immediately goes down, you can focus efforts on that service and why it may be contributing to the behavior.
