BlackVue Firmware Upgrade

I’m trying to upgrade the firmware on my BlackVue DashCam.
But when I run the upgrade program, my Avast says :
AVAST File System Shield has blocked a threat.
No further action is required.
Object : F:.…\BlackVueSetup(HD)_2.22.exe
Infection : Win32:Malware-gen.
Action : Moved to chest
Process : G:.…\DR550GW-2CH_v2.000E(2014.02.19)_Setup

Is this a false positive ???
