Speed up, tune up, and optimize your Windows PC

Your PC isn’t getting any younger. Fix what’s slowing you down with Avast Cleanup Premium’s patented breakthrough technology.

What’s slowing me down?

The more programs you install and use, the slower your PC becomes for three main reasons.

Startup items

Background processes

Scheduled tasks

Startup items

Many programs run automatically when you turn your PC on, significantly slowing its startup time.

Speed up with Sleep Mode

Our PC tune-up process detects performance drains and stops them for you, without making you uninstall programs or interfering with your PC.

Time to sleep

Switch on Sleep Mode to freeze any program that’s slowing you down. While asleep, it won’t use up any resources.

Wake up

Launch the program you put to sleep, and let our smart algorithm automatically enable all of its background activity.

...and back to bed

Once you’re done using the program, we automatically put it back to sleep to stop it from slowing you down.

The more programs you put to sleep, the fewer you’ll have running in the background, and the faster your PC will be.

Remove junk programs and bloatware

Identifies bloatware and long-forgotten programs

Your PC could be slowed down by programs you haven’t used in ages or never wanted in the first place — trial versions, unwanted toolbars, or preinstalled software. These are a waste of space and speed, and may even be a security risk. Our new Software Cleanup feature gets rid of them once and for all.

Clean it all up

Take the guesswork out of figuring out which programs you no longer need with our cloud-based reputation and unneeded-program detection systems. If you’re afraid to uninstall, we can temporarily put files in quarantine until you decide.

Defrag & care for your hard disk

The ultimate boost for your HDD

Defragmenting is a key factor in PC performance: It’s the process of re-arranging files on a hard disk for faster access. You’ll enjoy faster startup times, less loading, and snappier performance overall.

Cares for your SSD

Newer PCs come with ultrafast flash-based storage (Solid State Drives, SSDs) that don’t need to be defragged. Our Defrag detects SSDs and prolongs their health.

Give your PC a proper clean up

Running out of disk space? Not anymore. Avast Cleanup scans your PC from top to bottom to remove gigabytes worth of leftover junk files from more than 200 applications, browsers, and even Windows.

File system errors

Your hard disk is structured like a book: An index pointing to chapters and pages. If this index is broken, your PC suddenly can’t find files or folders anymore. This can lead to missing files, applications no longer working or even Windows crashing. Our Disk Doctor checks for such structural errors and fixes them in no time.

Update your programs automatically

Outdated programs can leave your PC vulnerable to bugs, crashes, and security risks. Our new Automatic Software Updater regularly updates your most critical programs for you.
