I have looked at this post and identified the services svchost eating up memory

Also yesterday I fixed an issue with a corrupt user profile service failed to start I used the technique in this video to fix that and edit the registry. I notice the User path was pointing to c:\users\Temp instead of c:\Users\Mike. The next day I booted up and my logon icon changed from the default flower to the jumping jack icon. This made me a bit nervous.
I am worried I have sometype of virus because all the games are running slower in general. I scanned with MalwareBytes, AVG, MS MSRT. Nothing was found.
Any advice where to go from here?
Edit: I also just notice my screensaver was disabled.
