Not necessary since I caught it at the time. I posted this for others who may be thinking of using it as additional protection because not everyone reads the fine print and the number of MVPs and Community Moderators who casually recommend third party software (especially virus scanners) without actually making clear the risk before they send people to various links and say DO THIS TO SOLVE YOUR PROBLEM with no warnings at all I just wanted to remark that there are issues here.
Not everyone is as advanced in tech savvy as you are and not everyone is necessarily even going to notice, at first, that this third party cleaner they were told to use cleaned out some essential .exe files necessary to running windows.
Not, at least, until they try to restart their computer and can't because essential files are missing.
What are you saying? That you would prefer I NOT warn people who may be new to all this?
And, if so, WHY???
