I got a new computer recently and ever since I have been getting  various errors saying itch Io is unsafe whenever I attempt to play any web games or download the itch client or download any games. It is complaining about some kind of security certification most of the time. Bit defender blocks it first, If I turn that off Firefox blocks web games, chrome it basically can't find them and so does explorer. If I try to download something from itch with bit defender disabled I get a big red screen from Verizon saying that it's unsafe I can't get past. But it's not the ISP because I can access itch on other machines connected to this network. I can't figure out what could be going on here.

Any ideas would be super helpful! Thanks in advance.
