I just downloaded DJI assistant v1.2.0 from DJI's site and installed. After the install Norton Antivirus (Fully updated) said it had found and removed Trojan.Gen2 from the install. It was contained in visionstarter.exe which was installed in c:\program files (x86)\dji product\dji assistant 2\assistant\

This would suggest that you web site has been compromised or a Trojan was purposly placed in your software.

FYI

NAV report

False positive?

Same here, not liking the fact that DJI has done nothing about the p4 firmware fiasco for 7+ months and now this?

You really believe Nortons? A company whose whole existence relies on finding and identifying viruses? If it has, as claimed, removed the threat, then it has taken a lump out of the software and it will be useless anyway.
