I am officially an idiot.
I have a gazillion bookmarks in my bookmarks bar. I also have way too many folders in my "Other Bookmarks" in Chrome.
Fortunately, Acronis True Image would not let me do a restore from my USB drive (my last restore was 12/23/16 - note to self, restore every Saturday.) That was going to be a PIA as I would then have to go to some USB drives to then move some critical files, such as my podcast files, back to the system. The issue: When I last backed up my PC via Acronis, my USB drive was apparently named H: - now when I plug it in it shows as I: Even when I switched the USB to I: and it sees it, since the backup was from H:Seagate it would not let me do the backup from the I: drive. So I was googling how to reassign the USB drive to I:, etc.
But then I went searching for something and - long story made short - realized that all of my Chrome bookmarks WERE there. The reinstall just changed their order. DUH.
Also - while farting with all of this I tried a program called Adware Removal Tool. It found about 25 things, removed them all, and for the moment the popup for the malware file is no longer popping up.
Now I just need to find a much easier to use bookmark manager for Chrome. Make sure sync is on, and also do a bookmark backup. And other backups. (I started a thread on best NAS for home use for media storage and backups, but put that on pause due to the cost...)
