How do I resolve the error 'Your Connection is Not Secure'?

I'm on the Sony Vaio, using Mozilla Firefox but I keep getting this error on the majority of websites.

Where is this coming from and how can I fix it?

Any help would be gratefully received.

I also have Bit Defender (in case this has anything to do with it).
