Ctrl-Alt-Del and "turn off computer" disabled

[financed]

Can anybody help me ? I found a virus on my system (WXP) called AD.DLL (advanced keylogger) which I managed to remove with anti-virus sw bnut since then the Ctrl-Alt-Del function to call the taskmanager is disabled as well as the "turn off computer" button in my start menu.

I was told to run sfc / scannow but this does not solve anything. Any ideas ?
Thx

Just wanted to ask, why do you think it is an Advanced Keylogger?
I know there's an Advanced Keylogger by SoftInfinity (

), but as I've had to install it a while ago, I want to make you sure that this one isn't theirs, though.
