@LukeAlmighty from what I understand, genuine products don't, it's the ones that try coerce or blatantly blackmail people into upgrading or purchasing "extras" like registry cleaners and disk cloners etc. A lot of those "extras" verge on Malware. Also, "Antivirus" programs that tell you things like "you're trying to uninstall, if you do, you'll be unprotected!".
