Anyone know whats happening here? Contrary to popular belief I think I caught a Trojan from a family member. My Email had all the address books stripped. So I thought it was time to beef up protection with my favourite AVG. But its not installing.

My MacBook Pro (15"Retina mid 2012 SSD) has allow all downloads. 
The OS is ElCapitan Ver 10.11.6, which I believe is the latest version and is always fully updated.

I have downloaded the file, but it wont veryfy or unpack.
