Blocking this url started today. Using FireFox 61.0.1 (64-bit) I have run Norton Security LiveUpdate.
I contacted Norton support, chat:
"We are aware of the issue, we were upgrading our server, but the issue is now fixed."
" Since we were upgrading our servers to latest Virus definitions, we were getting this error. "
" However, our engineering team has confirmed that issue has been resolved, please run Live Update and restart your PC once."
I performed a repair on Office Professional Plus 2010 (Control Panel\All Control Panel Items\Programs and Features - select Office Professional Plus 2010 - Change (at top) - Repair) then rebooted the PC.
All is back to normal.
