Stolen galaxy tab with Avast on it.

Hi guys,
I have a dilemma…
My Galaxy Tab 3 was stolen and I’ve been trying to track it.
I’m trying to do this before the thief shuts down my google account.
I tried Find My Device but it only gives me the online status…all other fonctions don’t work because remote access has been turned off. I just realized my tablet has Avast on it…but I’m unsure about how to proceed.
Can anyone please help me nail this sucker to the wall?

Thanks!
