winrscmde Trojan?

A couple of weeks ago, Nortan detected a Trojan on my computer and it went through the process of deleting it. Since then my system has gotten slower and slower. Simple internet searches take several minutes, and some times direct me to place that are clearly not where I intended to go. Games also take an extended period of time to load. I did get a couple of blue screens when trying to open programs as my computer was loading, but they quickly disappeared before I had a chance to read them and see what the error was. The computer would then reboot.

In the past couple days I have been getting the error that "winrscmde has stopped working." When I searched this online I see a lot of results indicating that this is some sort of trojan. With several different instructions on how to remove it. However, I don't know which (if any) I should trust.

If there is a standard set of instructions on how to fix this can someone please point me to it? If not, can some one please help me fix this?

Thank you in advance.
