I remember a buddy of mine a while back installed Ad-aware, Spybot, and SpywareBlaster on his Vista system to clean it up. He also installed other items, including a Logitech webcam that was not compatible with Vista yet, apparently (this was a few months back).

After everything was installed, it had a hard time shutting down. So, he did some research and found that the webcam was not really compatible with Vista at the time. So, he uninstalled those drivers. It still had the problem after that. Not sure what he did after that.

Are all of these programs 100% compatible with Vista now? If not, what programs would you suggest using to take their place?
