Year End Update 18.2.2 recognized as URL Malware by Antivirus Software.

We upgraded from 16.1 to 18.2.1 a couple weeks ago with just a few problems that have been resolved.  We received the Year End update 18.2.2 today, but when we tried to download it, our Antivirus Software detected it as URL Malware threat and kept it from downloading.  Any suggestions or advise on how we should proceed?

Thank you.
