Software Piracy

When someone installs and uses commercial softwarewithout paying for the program, it is called "pirating" the software. This name comes from the traditional meaning of the word "pirate," which is a sea-faring criminal that steals and loots belongings from others. But far from the stereotypical sea pirate, a software pirate can be anyone who owns a computer. Link from: http://www.techterms.com/definition/piracy
