I had this problem, it turns out that after the KIS 2015 post install reboot, my system clock was reset the motherboard creation year (2009), but the same date. Once I set my clock to the right date and time, the SSL certs stopped freaking out by my websurfing from the past. I upgraded another newer PC to KIS 2015 and didn't have this problem. Then again, its motherboard was made this year..... I don't know if KIS 2015 is the culprit or not, but I figured I'd share my solution to the problem.
