This virus called created some files called cssrss.exe and rpcc.exe. When I do to boot the system, I started getting Stop C000021A Fatal Error. Windows Logon Process Terminated Unexpectedly. (0x0000005, 0x0000005)I checked the MS KB article and tried the steps with no results so I did an "in place upgrade" or a repair install of windows. The first time it booted after the install, everything worked just fine. I then powered off the pc and restarted and immediately got the stop error again. I then restart the pc in safe mode and it comes up fine, then do a restart and real mode comes up fine. I am able to work in windows normally, no issues at all. I then do a warm reboot and again it comes right up to the user chooser with no issues. I then try a cold reboot and it will get to the blueish screen that says windows is loading then go to a black screen then a BSOD with the same error.
