      What is junkware?

      Junkware, also known as “crapware” or “bloatware,” refers to any unnecessary software. It may have been preinstalled on your PC when you bought it, or it may have snuck onto your machine as part of a bundle with other software you downloaded.

      What is junkware used for?

      Junkware is essentially a revenue stream for device manufacturers — app creators use devices as a marketing channel by paying for their apps to come preinstalled on devices. You can clear junkware and free up space by heading to this junk removal tool download page and using Avast Cleanup.

      What makes junkware a problem?

      Junkware clutters your machine, uses valuable space on your hard disk, and burns through your CPU power and RAM.
