Been using it without incident for several months, however about 3 weeks ago, some update it ran caused certificate security warnings to popup on many sites, and in every browser loaded on my system. Naturally my 1st thought was to check all the windows and individual browser settings which govern such things, but all were set as they should be.

I searched the web, tried everything I was able to find, no luck. Finally I disabled the security suite for 1 min, and they ceased. I didn't understand because the phishing guard in Kas. Suite was disabled, which to my mind is the only thing that should be warning me about website certificates.

I eventually had to tell it not to scan any traffic through the browser, something I didn't care for at all. Furthermore, I don't think an AV or FW should override such settings which govern annoyances.

So if you're considering Kaspersky suite, you might want to look further.
