There had to be more to Ctrl-Alt-Del. I assume you just chose these two to deal with.
start-run-msconfig-startup tab. Uncheck what you don't want to start. They can be rechecked later.
Be sure your Antivirus is up to date, as well as AdAware and Spybot, and cleaning has been done.
Also scandisk and defrag.
