I downloaded a file for a graphics application, clicked NO for any bundleware and it installed an AV scanner, a VPN app and some other heap of crap behind the scenes. To manually remove all this chyte would have been a nightmare but with Revo Pro unistaller, it not only removed the crap but tracked down any left over junk as well.
You can get a free version of it that does most things, I paid for the pro version as it does a bit more.
Just to be careful, I ran Kaspersky's KVRT.EXE and nothing turned up so all is well.
