So, I'm downloading some files in Firefox, and there is this file that keeps popping up with an exe. However, it only appears when I'm saving my file to a specific folder. As in, I only can see it when that happens. When I'm actually in the folder, I can't see the actual .exe Since this is a pretty new Macbook Pro (got it on Friday), I'm not sure what's wrong with it. I haven't really downloaded any "shady" programs, most of what I have are the normal applications, with the possible exception of a flash card program that I JUST got. I'm having trouble reproducing it at the moment - I'll post screenshots once I do. The .exes are always a mix of letters and numbers.
