I get this message when opening trusted websites, can anyone help please!

Re: security message
 

Do you have the correct date/time?

Re: security message
 

Yes, time zone & settings OK.

Re: security message
 

I get it as well (found the site from the 'Continue to the site' link)

The security certificate they are using seems to be a self-signed one - it's not issued by any known signing authority

Re: security message
 

Its just started to appear on facebook & other sites I frequent too.

Re: security message
 

I'm not getting it on either Chrome or IE.

Re: security message
 

Yep, Ben's spot on - self signed certificate, nothing you can do about it.

Re: security message
 

Why would it suddenly appear, it was fine yesterday?

Re: security message
 

Have you done any updates?

Re: security message
 

No, last update was a windows update, 3 days ago. I haven`t downloaded anything, the link I posted is from data cave, but facebook is the same. I`m stumped?

Re: security message
 

Could be a browser glitch I guess, or something affecting the way the browser interprets the trust chains for the certificate signing.

I get the same issue on the 'datacave' site in the link above though, so that's definitely the issue with that one site.

Re: security message
 

Thanks for the replies guys, I don't have a clue, if I find anything, I`ll post it for future reference.

Re: security message
 

At least you`re actually questioning what`s going on SMG ,which is more than many will do when presented potentially bogus security certificates.
Many people seem to click next & continue etc the same way they blink & breathe, completely subconsciously.

Re: security message
 

Kudos to SMG for picking up on this and actually asking the question :tu:

It seems like they have done there own DV certificate which means that the information transferred between you and said site is encrypted and that it`s a valid domain. This does not mean diddly squat about who owns the site or what services they provide (some fake AV sites have DV for payment).

Like others have mentioned because this is a self signed job they will not be in the Root certification list of your browser, for IE look under Tools/Internet Options/Content/Certificates/Trusted Root, in FX Tools/Options/Advanced/View Certificates (you`ll see the likes of Verisign, Comodo, Equifax).

Something i allways try to do now is to alert people to the fact that when they go to payment sites, banking sites, etc and are putting in sensitive data they should look out for the address bar to turn green or have the green site identity button. This means the site has EV and has been checked, ownership wise, etc.
It`s starting to sink in but slowly.
