Okay, guys, I'm doing things bit by bit as I can.
I just installed CCleaner. Two questions at the moment:
1. Should I delete the "ccsetup319.exe" desktop file it created?
2. I see that CCleaner has an "Uninstaller" in the Tools section. Might that be a better uninstaller to use for removing MSE than the Windows Add/Remover Programs??
Appreciate all your help.
Not exactly sure when I'll set the uninstall of MSE in motion. Hopefully, tomorrow given the time and the ability to work up the courage.
