It wouldn't complete an upgrade on a Win10 Pro system (no doubt due to some other things I run), asking for a reboot and then not continuing after the restart, so went with a a Clean Install. Everything running well. The theoretical vulnerabilities referenced and fixed, are way above my skills sets to verify . . .
I noted there was a slight update to Secure Shopping, but this again is the only Comodo module (and other software) I've found that still insists on the standard Temp folder Environmental settings - instead of a RAM Drive, so I had to fiddle with that again!
Still find about a dozen unrecognized Vendors after the install - only 2 of which are running any software on my system, so I deleted them along with many others in pruning the list down
Apart from that, all looking fine
