Scammers are using clipboard malware to create similar vanity address with one you are using, so you always need to confirm if all characters in address are the same.
Best thing to avoid this problem is to use separate offline computer made only for crypto transactions, or to use open source hardware wallets.
It could help temporary if you clean up or even better reformat your computer operating system.

Chances of getting your coins back are minimal, but you can report his address to authority and try to track him and his connected identity on centralized exchanges.
I am not sure paying someone to find him/them is worth it for your 0.016 BTC, but you learned your lesson for future.
Not sure what operating system you are using but using Linux is much safer option, and for wiNd0ws you can use Malwarebytes to scan and clean your system.
There are also software solutions with clipboard protection but you need to do more research about that yourself.
