Since I updated to version 113.0.2 every time I try to open certain websites, Firefox shows an error message "SEC_ERROR_UNKNOWN_ISSUER". Once I choose to accept the risk and continue it redirects to the IP address "79.137.248.81" that redirects to spam. This happens on multiple sites, certain popular sites such as google work perfectly. Yesterday I uninstalled and installed the browser. I rkilled and scanned my system with Malwarebytes, Avast and HitmanPro. I also have no malicious addons I found. Nothing worked. I am attaching pictures of how the error shows. Please Help.
