Fusion 360 download infected with virus

[itretail]

Just tried to update Fusion 360 from within the program, but the download was trapped and quarantined by my antivirus software with the message

We have moved to your quarantine because it is infected with Win64:Evo-gen [Trj]

AVG Internet Security

I got the same thing with Avast antivirus on my Windos 10 PC. The upgrade appeared to finish okay but I don't know if it really updated all it should.
