Since a few days ago - I believe it started after the Daylight Saving Time change - I can't open websites that use HTTPS connections, such as Yahoo, Facebook and Youtube, on Chrome or Mozilla Firefox. Internet Explorer opens them normally though, and I can also browse those sites on my tablet.

The message I get on Chrome is Your connection is not private, and Firefox says that This Connection is Untrusted:

I have checked my system time and date, and they are correct. I've also tried reinstalling both browsers and disabling my antivirus and some other programs, but that didn't change anything.

Using the ipconfig /flushdn command on a Windows command prompt window fixed it for a while, but some hours later I started getting those errors again.

So, if not the date, the problem is stemming from a parental control system called McGruff SafeGuard. This system provides it's own certifications so it can decrypt emails, and sites you visit Even over HTTPS. Because the certificate it is providing isn't working, any HTTPS site will not let you continue.

If this is installed on your computer I would recommend uninstalling it and trying to see if it works.

However if it is not on your computer, but on your network, contact your network Admin and alert them that this security system may be causing problems.

Hope this Helps!
