How do you know you been scammed?
If you believe you were, changing passwords is a good start. But maybe not do that on a system you think is compromised.
Booting up with a secure boot disk or usb stick and scanning for hidden surprises and otherwise scanning your system thoroughly might help too.
I tried three different scanners, and the file you claimed is a scam, was not recognised as such. Of course I will not execute it to check if it silently steals my passwords anyways. If it really is a scam, this is worrssome.
