Uninstall means different things, and they never uninstall completely/cleanly. In this Superfish example they would have left the dodgy certificates behind. The only way you know you have a good install is to do a clean install, rather than attempt surgery on the crap that got shipped. Fortunately Lenovo do have a system updater that does a fantastic job on driver downloads etc.
