What’s slowing down my device?
The more programs you install and use, the slower your PC becomes for three main reasons.
Startup items
Many programs run automatically when you turn your PC on, significantly slowing its startup time.
Background processes
Programs could be running in the background even when you’re not using them, hogging your PC’s memory and CPU.
Scheduled tasks
Your software often sets its own schedule and can suddenly come alive, using up resources and slowing down your PC.
Improve your PC’s performance 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.

Effectively remove harmful bloatware
Bloatware refers to all the preinstalled software you don’t actually need and probably don’t want: apps you don’t use, distracting toolbars, expired software trials, and adware that plagues you with popups or even spies on you. Avast Cleanup will deep-scan your machine to root out every trace of PC bloatware.

What’s automatic maintenance?
Your PC accumulates a ton of wasteful data every day but we’ve got your back. Our automatic maintenance regularly and automatically removes these junk files for you.
Clean up your browser and disk
We remove the leftover cache files and traces from your browser, programs, and Windows.
Removes broken shortcuts
Clean up your desktop in seconds by deleting all those “dead” shortcuts you never use.
Cleans up your registry
The registry plays a critical role in any Windows operating system, so issues here can result in program crashes and error messages. We fix your registry automatically as part of Avast Cleanup’s regular maintenance.
Disk Doctor
Over time, your hard disk file and folder structure could become damaged, leading to data loss and crashes. Our Disk Doctor prevents errors and cures your disk 24/7. Here’s what we check and fix:
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.
Data integrity
Files on your disk can become corrupt for various reasons, such as sudden power losses. Our Disk Doctor detects such errors and helps to fix them.
Access rights
If you’re getting “You don’t have the privileges to access this file” (or similar) messages, then the access rights of files and folders got messed up. This can happen after an update, the installation of an application or even after a virus attack. Disk Doctor checks for such errors and tries to cure them.

Why do I need software updates?
Software updates can be critical to keeping your PC running smoothly and safely. Here’s why you shouldn’t ignore them.
To avoid security risks
According to our data, over 55% of all installed applications worldwide are outdated, leading to potentially critical security issues. Our Software Updater helps patch security holes for you silently, saving you the hassle of finding, downloading, and installing the updates yourself.
To fix bugs
Bug fixes are part of many updates, so Software Updater helps you enjoy your software with fewer annoying crashes and error messages. We support the most popular applications, such as Adobe Reader, Skype, VLC Player, and WinRAR.
To get the latest features
New updates often bring new features. For example, VLC Player 3 added support for up to 8K and HDR video — something you’d miss if you never updated. Software Updater installs the updates for you automatically, so the next time you open your favorite app, any new features will be ready to go.
