If I attempt to simply login my browser to www.senate.gov the attempt is rejected with the message: "Sorry, a potential security risk was detected in your submitted request. The Webmaster has been alerted." No further information is provided and the webmaster doesn't answer.

I get this on both Firefox and Chrome,but don't get it trying to connect from my ipad, so it appears to be specific to my Windows 11 Dell G16 laptop, which has all current updates and passes a full virus scan by TotalAV.

Any ideas on what to do next? Is there a site I could try to connect to that has very high security detection and ALSO will tell me what the problem is? Thank you.
