Hi Flood - your questions are certainly not annoying and I thank you for the time taken to help me. You have a little problem with me however in that although I am reasonably competent on my PC I get a bit lost by "screen prints" "Zip folders" and "Cloud" etc etc. - sorry - however I will try to give you as much info as I can.
The message that I get is similar to the one you show but not exactly. It says "Connection to Network is not secure." "Wi Fi Network, (name of MY network), is public". It then invites me to "Run Kaspersky Secure Connection" which if I click this - it connects me via KSC and I get the message "Connection via, (name of MY Wi Fi Network), is protected via United KIngdom".
So yes KSC is installed - have confirmed via my list of apps but I do not have the "Icon" on my desktop for some reason which confused me. Although I have been getting this message for some time I have also been aware that if I do a "search for available Wi Fi networks" I can see my network name and it is shown as "Secured ". Also if friends come and want to use my Wi Fi I have to give them my password in order that they can connect. Surely this means that it is not Public and the message I am receiving is in error? Should I now look at my KSC configuration settings as you suggest? or Uninstall KSC and see what happens? Appreciate your help - Thank you.
