Honestly, there's WAY too much software out there for me to list all of it I've used or approve of, so I've decided to list the Windows software(s) which I habitually wipe out on sight. Many of these are not malware but rather things I don't like. They do things which run afoul of my software rules. Most of this list swiped from the Wikipedia page on Adware.
