AIS FW - Application recognition

I get an Application Rule for ‘Other’ created by AIS FW - see pic.

It’s actually a Panda usb vaccine file - but for some reason avast doesn’t associate the file name (which it gets) to any Application name.

An Application Rule for ‘Other’ is at first sight a bit disconcerting.

I realize avast has a general ‘default allow’ policy, but if an Application name can’t be recognized I wonder if this might be an occasion where it might be better to default to ‘Ask’?
