I have the same or similar problem. When I start my computer, I get immediately a message from Kaspersky Total Security: "Cannot guarantee authenticity of the domain to which encrypted connection is established.
Application: Google Chrome
Reason: Self-signed certificate
Need to click "Disconnect" many times before this message disapears. Comes up again the next time on start-up. Started happening about4-5 days ago. What is this? And how to get this fixed? Happens with well known, trustworthy websites.
