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 gotten onto your machine as part of a bundle with some other software you downloaded.

What makes junkware a problem?

Junkware clutters up your machine and takes up valuable space on your hard disk, while also burning through your CPU power and RAM. Not only that, some junkware is actively malicious. It can carry malware or act like adware or spyware, compromising your security and putting your personal data at risk. That’s why it’s so important to remove junkware from your computer. A cleaner PC is a safer, faster PC.

How do you use the junkware removal tool?

It’s easy to use the junkware removal tool in Avast Cleanup. Simply open up the program, click Speed up, and then select Unnecessary programs. You’ll see a list of apps that can be safely deleted.

If you’re not sure whether a given app is junkware or actually legitimate, our cloud-based reputation system can help — it displays a star rating so you can see how other users have rated the app. You can also choose to put the app in “quarantine” to simulate deleting it. Later, if you find you’re not using the app, you can remove it — or reinstate it if you decide you want it after all.

Is our junkware removal tool safe?

Absolutely! Avast Cleanup was developed by optimization and security experts, and it’s completely safe. Our patented technology will find and root out junkware and other unnecessary files, while making sure not to touch any files and functions you need for optimal PC performance.
