Bundleware is a term used to collectively describe one or more software that comes in bundles as extra. This isn’t necessarily malicious. Bundleware that are dodgy at best have a few types:

  • Programs that are considered adware and PUPs. These may or may not offer users the option to opt out of the extra programs.
  • Programs that are useful but nobody wants to pay for their functionality, so the developer enters some monetization program that incorporates adware into his/her program.
  • PUPs that offer to install other PUPs from the same manufacturer during the installation.
  • Programs that also install software packages they need to run on the affected system.

Malwarebytes detects these types.
