Firefox automatic update problem

[Deleted]

I think it will do no harm here to repeat that my computer got a severe dose of Malware yesterday (17th November 2017), via an automatic update from Firefox.  I'm puzzled about what I could have done to avoid it, other than to have MalwareBytes running continuously, which blocks all sorts of wanted items as well as the dangerous ones.  I presume the powers that be at Firefox will be doing their nuts looking for a solution to this problem, but in the mean time it might be prudent to remove Firefox from ones computer, making sure first that all the information it contains is backed up first, in case it doesn't automatically transfer across to Internet Explorer or whatever.

I did initiate the update manually quite early so am hoping I avoided this.
Just the other day I downloaded a Windows 10 repair tool from Microsoft which can sit on a Flash Drive until needed.
I suppose older version might have something similar or the compute might have a repair/recovery option?
However, if run it will revert the machine to an older state and there will be a lot of updates to catch up with.

One of the problems with what's happened 4WD is that the malware has disabled the restore function. Of course (shining halo) I do have a set of system backup DVDs - err - but I've lost them! Bums!

I don't in fact keep that much on the computer, and the data files get backed up tolerably regularly, but I think I need professional help re-installing Windows while not wiping Microsoft Office, which is not cheap these days.

I sat at the end of the house looking over the moat, with a glass of wine, about half an hour ago. I went indoors when penguins started appearing in the wine.
