ccsvchst.exe bogs down system after virus detected

a few weeks ago, I got a "downloader" virus and my machine locked up.  I rebooted and windows would keep rebooting itself before the login screen, even in safe mode.  I then left it for week came back and it booted up.

 

So then I ran a full system scan and it detected the "downloader" virus. Within a few minutes of login into windows, ccsvchst.exe takes up 99% of the resources and I cannot close norton.  It got stuck on the "one click support" window or something like.  It just sat there and with the status of "processing" for hours. I could not kill or adjust the priority of ccsvchst.exe in the task manager.  I gave up on a full system scan after 10 hours.
