And I dont want it! 

So - how get I rid of it?

Please answers for dummies!

Fortinet Webfilter = Pages are blocked by a filter that says, for example "Block all blog pages", or "Block all gambling" pages. This can be done on 2 places:

1- your PC, through FortiClient. This application is installed on the corporate PCs to apply such filters and protect/restrict the usage of the PC. This is done automatically by your company (security department). If this is your private PC, and this software is not installed, than continue to:

2- the first firewall that filters your traffic. It can be your home FortiGate (router), a residential router, or an Internet Service provider router. If you don't have a FortiGate that you manage (and you can set up), then you need to contact the company who provides the internet connection to you.

You need to update certificate at the site's host like recommended in below Wordpress discussion:
https://wordpress.com/forums/topic/security-certificate-expired-1/

 

At the FortiGate, which is blocking sites with expired certificate, you can either create a SSL inspection profile to allow those sites (ignoring them) or skip all inspection with "no-inspection" profile. But I guess you don't want to even deal with it in your current stage of the problem. So I recommend you to solve the origin of the problem at the host.

Thanks, Toshi, for your answer!
But: 
First of all, how do I update certificates of any website, witch is not me? And do you really think a dummie like me, who doesn't know, what Forti is, can update half of the world?

 

Second: I don't have FortiGate. So - how can I creat anythink there, without having it?

 

And third: There are a lot of pages, I cant surf any more. So - how can I solve the problem? (See First!)

Hi. You have a corporate client with FortiClient installed? If so, check the clock (date/time) in the client. /C

What the hell is a "corporate client"? I've installed nothing, whith is name with "Forti" at all. Is is like a virus. Since some days I can't surf to sites. In before I got the message like: "Unsave site" and I could klick to a button like: "Go ahead, it's ok for me and this site".

So - where does a program come from / with, what is doing things like that?
And the main question: How do I get rid of it?

So, this is at home? Then I advice you talk to your Internet Service Provider to find out what's going on... /C

Thanks for answering.
I now think this hits the problem. 
It's a privat computer and a private router. So I can say - I didn't install anything like "Forti". 
So I tried to trick my internet-service-provider (ISP). Made a VPN - and I could surf like before. So - that must be a filter of the ISP. 
Thank you. Looks like this solves the problem.
