would this help protect me from possible keylogger? security

[blakeroberts]

Hi, ive been sent a macro from someone and i want to test it, but cautious as its encrpted, i was wondering, if i used a firewall, would that prevent qm from sending any information if it was a key logger?

as its supposed to be functional as in do some "other" automated task.

or anyone suggeset any counter measures apart from "dont run it" lol, thanks
