Winrscmde Trojan? plus Norton error 5013,3

My system has been slowing down for several months. I've had blue screens since 11-19-12 and resolved enough problems to get online yesterday. I installed Firefox and my system screams once again. But I keep getting Norton error message 5013,3 on every boot. I did the Norton deep clean on several of these boots each stating the scan did not detect anything.  I saw svchost.exe hogging system resources message from Norton but wouldn't have devoted attention to it thinking that it was normal, and that Norton has me protected. Then I recieved the winsrcmde has stopped working message, and a request to send results to Microsoft. After searching 'winrscmde' I saw results that warranted me arriving here. This is where my system currently sits...

I have not approved sending details to Microsoft (they seem to be degrading my system not improving it) and yet I was just issued another message that winrscmde is hogging resources.  It is hung, and still running apparently.
