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.
