I used to have issues with Bitdefender updating on my Macs at home. That has worked fine once I got past the initial download (I had to exempt my computer from scanning the Bitdefender installation file).
Now, the Windows 10 machine cannot update. I created an exemption for the Bitdefender domain under Protect -> Web -> Exemptions. I exempted the domain from all scanning and filtering. That did nothing. Bitdefender still would not update. Interestingly, it would get as far as 98% before it quit. The ONLY way I could get it to work was to create a new firewall rule for that particular computer that allowed all access to WAN without any filtering. On the face of it, this would seem to be the same thing as creating an exemption rule. I have the feeling that the exemption rules don't exempt all the things that are requested...
At the moment, it is a pain to create a firewall rule each time we need to update Bitdefender on the Win10 box...
