msi A6200
Windows 10
I am cleaning up someone else's computer (lots of malware) but the one app I cannot get to uninstall is TuneUp Pro. It is not listed in the Add/ Remove Programs category in Control Panel > Uninstall. I have tried manually deleting all of it's entries in the Registry using regedit, but it just reappears (maybe I'm missing a step or some) I have downloaded the MS Fixit utility and it is not listed, so I clicked "Not Listed," then it asks for a product key, which I don't think there is one, or at least I don't know how to find it. I also tried using CCleaner but it does not list it under programs to uninstall.
How do I get rid of this malware?
