If you're using Vista Ad-aware2007 does not show in the processes listed in the task manager, so it cannot be stopped and the error message keeps appearing. Ad-aware cannot be stopped, attempting to remove it by using Vista's Uninstall doesn't work either.
I eventually tried MikeB's method of removing it, having been sceptical, and it works. I wish I'd tried it sooner.

Type msconfig into the start box, go to start up and unclick Adaware.
Restart the computer then go to Control Panel > Programmes > AdAware > Remove
A warning message appears, you need to allow Lavasoft access.
