How to recognize a malicious scr file?

Question

Malware

In a telegram from the “customer” I received an archive with a “technical task”, an archive with a password, inside the scr file, for the first time I encountered this, I tried to run it through AutoDesk, nothing was reproduced, and only after doubts arose, tell me how to check if this file is malicious, and if so, did it have time to install and where to wait for the threat now (if it is important, the topic of the order concerns the crypt, so there are even more fears)
Thank you
