Thanks cl_out, but I managed to get the Task Manager working again.

I ran this command:

REG add HKCU\Software\Microsoft\Windows\CurrentVersion\Policies\System /v DisableTaskMgr /t REG_DWORD /d 0 /f

Which instead of removing the key, just made my task manager usable again. I apprecaite the response.

My problem lies more in that I don't know what other damage, if any, was done.

I found the key that was in SOFTWARE\Microsoft\Windows\CurrentVersion\Run and removed it, but aside from that, I can't seem to find anything else.

Norton Antivirus did not pick anything up, but then again, it didn't pick anything up before I ran the file.

And lastly, I've found this in the registry:

pmlzjxgec = C:\WINDOWS\System32\bmulalme.exe

I'm to understand that bmulalame.exe is for Quicktime, and auto-updater of sorts, but what looks suspicious to me is the "pmlzjxgec", which I have no idea what it is.
