So I've just upgraded to win10 and go to install DJI assistant and get this...

Hi. I am sorry for the trouble this has caused. With regards to this concern. If the DJI Assistant 2 was downloaded from the official website or obtained through regular channels, you can install DJI Assistant 2 with peace of mind. Again, I am sorry for the trouble. Thank you.

It was downloaded from the DJI website, not sure what to do now was going to download assistant for Ronin-s as well.  

It's a commonly reported false positive.
Don't worry about it.

Thanks, was wondering if that was the case. Can never be sure sometimes

During installation,  disabled your Virus protection  temporary ,and after installed add the DJI Assistant .exe to excluted files so you will not get false positive virus messages.

Yeah, just make it an exception so that your virus protection doesn't mess with it.  It happens, as Windows 10 is more hardened than previous versions.

I had problems with installing DJI Assistant - my antivirus blocked even the installation... i have contacted DJI and after several email exchanged they confirmed that it is a problem and that will be solved in the new update of the app...
