If you're like me, you're probably cautious about your security, and don't wanna run an unrecognized program, especially from the cracks/leak pages on NulledBB, if you wanna test if the program you're downloading is a rat/virus/trojan/etc, use tria.ge! it's a online VM (virtual machine) that can help you test programs you're not too sure are safe, I've used it to avoid multiple encryption programs, viruses, ad-ware, and so on, happy downloading.
