I'm almost sure there was no other option than "accept", and probably didn't think it too much because I know there's a way to untrust certificates if I find out bad reputation online.

Well, I found "The USERTRUST Network" has been scamming before so I went to untrust it, but I didn't find it in the list. The name was (I copied it) "USERTrust Legacy Secure Server CA" by "The USERTRUST Network"

The buttons are not clickable for the whole category (The USERTRUST Network) and I couldn't find "cert8.db" to delete it, as I found in another post.

How can I find it or untrust the whole group?
