Hi Flood, Apologies for the lengthy delay. Ok. Couple of things; I understand the gist of what your saying but haven’t got a clue what to do, maybe I don’t understand some of the instructions. So, I will need your support to update & install Kaspersky stuff. Also, Kaspersky Protection extension has been moved or something, maybe I deleted it by accident, because I know that it was there. Incidentally, I followed the link to KIS20 incompatibile applications and on the list of apps that are incompatible I noted there was firewall & security app, called COMODO, this is my surname. No relation. Thought I would let you know in case any of the Kaspersky software is reading my name somewhere and deciding it’s a firewall. If this idea is ludicrous to you, it will at least give you an idea of my knowledge of IT & computers. So, I imagine that for you to assist me we will need to be online at the same time. So please advise on my next step & I will try to get back to you in a reasonable time frame. Thanks. Gulag
