A bundler usually refers to a single installation file containing two or more programs. Many of them are found in freeware download sites. Although in some cases, these “free” software are actually trial versions of applications one commonly pays for.

Bundlers bank on the names of popular programs users generally want to install onto their systems, and those who aren’t familiar with bundlers may welcome the additional free programs. Unfortunately, a majority of these are categorized as unwanted software, such as adware and browser toolbars.

A bundler also refers to software that is pre-installed in newly-purchased hardware (e.g. PC, laptop, smartphone).

Synonyms: bundleware, bloatware, bundled software, crapware, pre-installed software
