Thanks for your reply, Harlan4096. I'm afraid I'm almost a complete novice in this area, and seriously out of my depth! However, here are the apps listed on my computer: K Premium (one years subscription), K Password Manager (I haven't touched this yet) and K VPN.
Are you saying that I don't need that K VPN because I'm covered anyway by K Premium? When I open K VPM is says I have a free daily limit of 0-200 MB. But in Premium it's says I'm fully covered, so I guess that is what you're saying. In which case I'll proceed as you indicate. I just don't want uninstalling K VPM to affect my our Premium account.
