Frequent "Cannot guarantee authenticity..." prompts for Thunderbird

3 posts in this topic

Windows 8.1 Pro x64


Thunderbird 24.3.0


I frequently get prompted by KIS with the following dialog:


Cannot guarantee authenticity of the domain to which encrypted connection is established

Reason: This certificate or the certificate chain is built on an untrusted root center.




Before installing KIS, and when I first installed and set Thunderbird up, I had to add an exception to Thunderbird, but never had a problem after that.


I've installed the Kaspersky certificate.


Is there any way to prevent this KIS prompt, without disabling SSL in Thunderbird, SSL scanning in KIS, or switching hosts?
