Can't access sites due to 'security issues'

I get this security problem in every site I'm trying to enter:

(www.wikipedia.org uses an invalid security certificate.

The certificate is not trusted because the issuer certificate is unknown. The server might not be sending the appropriate intermediate certificates. An additional root certificate may need to be imported.

Error code: SEC_ERROR_UNKNOWN_ISSUER )

I tried every video, and every tutorial you have. No luck :(

I don't have any anti virus installed on my computer, and every other browser opens the websites just fine... (I'm talking about Google, YouTube etc... nothing suspicious).

I would appreciate you help!

thanks, so it appears to be the adguard software running on your system that is intercepting all secure network traffic causing this problem.

they have a page where they explain how to solve issues with certificate errors here: https://kb.adguard.com/en/windows/solving-problems/connection-not-trusted
