user @Krümel posted a possible solution, but I can not test it: Close FF/TB go in KL product to 'settings->network settings->Mozilla Firefox and Thunderbird' and select 'Use Mozilla certificate store'. Save settings open FF/TB close FF/TB select again 'use Windows certificate store (recommended)’ save settingsWith a little luck the message is gone now. I’m using Kaspersky Security Cloud Free and Thunderbird, Firefox is not installed. I started getting the “Secure traffic in Window Operating System not monitored” message a few months back, every time Thunderbird updates. My solution was to uninstall then re-install Kaspersky every time Thunderbird updated. After the re-install the “Secure traffic in Window Operating System not monitored” message is gone. This is what worked for me and just thought I would pass this on if it might help anyone or shed additional light on the problem.
