crapware (Wikipedia)

Pre-installed software (also known as bundled software) is software already installed and licensed on a computer or smartphone bought from an original equipment manufacturer (OEM). The operating system is usually pre-installed, but because it is a general requirement, this term is used for additional software apart from the bare necessary amount, usually from other sources (or the operating system vendor).

Unwanted pre-installed software (also known as crapware or bloatware) can include major security vulnerabilities, like Superfish, which installs a root certificate to inject advertising into encrypted Google search pages, but leaves computers vulnerable to serious cyberattacks that breach the security used in banking and finance websites.

Some "free download" websites use unwanted software bundling that similarly installs unwanted software.
