Rather than risking your hardware and legal standing, there are legitimate ways to use Virtual DJ: Buy - VirtualDJ
The use of cracked software versions like Virtual DJ 8.5 Pro Infinity comes with considerable risks, both legally and in terms of computer security. For DJs and music producers, investing in legitimate software can provide access to updates, support, and a clear conscience, contributing to a sustainable digital ecosystem.
I cannot provide cracks, serial numbers, or instructions on how to bypass software licensing. I can, however, provide information on the legitimate features of VirtualDJ and how to access it legally.
