security Is it a possible scam?

Hello Fiverrs,

I've just received an odd message requesting proofreading and voice over. 

The client sent me three files, the first two were suppose to be movies but the extension was BIN. The third file was a XLSX extension with didn't open. 

Oddly, my Fiverr app was updated at the moment I tried to open the third file.

I uninstalled Fiverr and installed it again, but the BIN files I've downloaded simply vanished. 

Can it be a scam to steal my Fiverr credentials or account? If so, which steps should I take?

Sincerely,
