Turn off promiscuous mode in Win7 guest

Host: Mac mini (Late 2012), 8GB RAM, 500GB HDD, macOS Mojave, Fusion 11.0.2

Guest: Windows 7 Professional, all relevant patches / updates installed

Network-related apps installed on guest: AVAST Antivirus

For a while, I'd had issues with my Win7 VM being unable to access the internet.

I recently determined I need to switch the network setting from NAT to Bridged, and which got the VM back online.

Now, I have the message each time I boot up the VM - "A virtual machine is attempting to monitor all network traffic..."

After doing some searching I found that the network is set up in 'promiscuous' mode... how do I turn this off?
