Lately my CTRL-ALT-DEL has not been functioning, also RClick and trying to bring up Task Manager does nothing. I read other posts concerning a '..has been disabled by your administrator...' issues some have but I am not receiving that message nor any other messages (error or otherwise). The two actions simply produce no response whatsoever. I also have Ad-Aware and have run it but it doesn't seem to help. Seems some spyware or something keeps popping up browser windows when the system is left on but unattended for a while. I come back and have a screen full of ads and windows and sometimes dozens of download dialogues asking for confirmation (Thank goodness I set securities to forbid these without confirmation). I can't ID or locate the culprit so any assistance would be appreciated.
