I sent Ed an email last night TW with all the details of the threat that Norton had blocked, but as yet I haven't heard anything back from them !!
Hope the powers that be can get to the root of the problem sooner rather than later.
Ed is probably not about until Office hours tomorrow
if it helps, I was using IE and Windows 11 when I had problems with AB, I changed to Chrome, scanned with Malwarebytes and so far all is ok,
good luck!
