Software piracy refers to illegally using, copying, or reselling software without permission from the creator. There are several types of piracy, including soft lifting (sharing software not licensed for multiple users), hard disk loading (pre-installing unauthorized copies), renting (temporarily renting software), OEM unbundling (selling standalone software meant to be bundled), counterfeiting (producing fake copies), and online piracy (downloading from unauthorized websites). Piracy can lower productivity, infect computers with malware, subject users to legal action, and financially support software pirates instead of legitimate developers and sellers. Laws prohibit unauthorized copying and use of software, and penalties can include large fines.
