Microsoft Visual C++ 5.0 [Overlay] ?

the best way to find out what you're dealing with here is to simply debug it. have a look at it and see. i know this is vague, but honestly that's the best thing to do.

i see these protector scanner apps as useful guides to let you know what you're dealing with and not a definitive step for deciding your next move should be. so when you get a result like [some normal compiler(overlay)] it's time to do some sleuthing for yourself

good luck
