Elias learned a lesson that night as he spent eight hours reinstalling Windows from a scratchy disc: in the world of software, if you aren't paying for the product, you—and your data—usually are the price.
With a held breath, he downloaded the file. It wasn't an installer; it was a "Keygen"—a tiny program that generated serial numbers accompanied by a loud, distorted 8-bit techno loop that blasted through his speakers.
