Your connection is not private - Message on Chrome
I've begun getting random messages when I'm logging on to secure sites (https) saying the above. It doesn't happen on every attempt to go to a site, but randomly, and if I try to reload the page it generally goes on without incident.
I don't understand why it would be random like this, and wonder if it's an issue with my Talktalk router, or with a potential infection on my machine.
I'm running with Bitdefender antivirus - bought and paid for.
