I downloaded ccsetup321.exe from FileHippo.
I cautiously delayed every click by several seconds to see if there was going to be any unwanted passengers, and saw no indications.
I was horrified to find a strange icon on the TaskBar and when I looked on the Desktop I saw a short-cut to Google Chrome.
Do I need to wait several minutes between clicks so a very slow warning will appear.
My first action was to use CCleaner to uninstall Google Chrome,
and was horrified to see that the uninstall pop-up included an option to make PaleMoon my default browser.
I delayed further action on that.
I clicked on a link to a favorite site and NOTHING happened.
I had not yet uninstalled Chrome and it was NOT acting as a default browser,
and furthermore it had destroyed the Default Browser capability of Palemoon.
Google Chrome is malware - it is a browser hijacker and destroyer.
I then checked the pop-up option to make PaleMoon my default browser (like it has been for months),
and completed the Chrome removal.
I clicked on a link to a favorite site and normality had been restored.
Actually it was semi-normality.
PaleMoon had been running all the time,
but after closing Palemoon and then opening again it wanted to know if I wanted to make it my default browser,
and that is a question it has not asked for months,
so Google Chrome left permanent damage that required further action by me.
That is the Unwanted stuff.
Intermittent stuff :-
It only happened once.
I tried this twice more and It is good that Google Chrome never happened again - and I could not even find any option to have it included.
I assume this MAY be because there is either a Google Chrome or a CCleaner registry key that is corrupting my system with the information that I do not want Google Chrome.
I have just run CCleaner Registry Scan and seen 4 separate ActiveX/Com issues with Google Chrome.
There are reasons why I prefer my software to be Portable and under my control.
I only ventured into this because I am intending to restore my system from a Partition Image backup.
