I just downloaded 32220-PropScope-USB-Software-207.zip, and Windows Defender immediately warned that it contained the trojan "Win32/Rundas.B". Can someone at Parallax confirm whether this is a false positive?
Edit: Good news. It seems to have been a false positive. After the next virus definition update installed, Defender no longer saw it as a threat. If you encounter a similar issue, just make sure the checksum matches the ones listed below.
Edit: Nope. I downloaded the wrong version. When I download the version in question, with the new definition file, I still get the warning.
