What’s slowing me down?

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

Your 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 and slow down your PC.

Speed up with Sleep Mode

Our tuneup 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 computer will be.

Junk programs and bloatware removal

Beware of bloatware

Your PC could be slowed down by bloatware — programs like trial versions, unwanted toolbars, or preinstalled software you never asked for. These files take up space and cause performance issues, but thanks to Avast Cleanup, you can get rid of them.

Clean it all up

Take the guesswork out of removing bloatware with our cloud-based reputation system. Ratings from people all over the world help you figure out what to keep. If you’re afraid to uninstall, we can temporarily put files in quarantine for you until you decide.

碎片整理和照管硬盘

硬盘驱动器性能提升

碎片整理是 PC 性能的一个关键因素：碎片整理就是重新排列硬盘中的文件，加快访问速度。启动速度更快，加载时间更短，整体性能更优。

照管固态硬盘

新式 PC 都配备了超快闪存（固态硬盘，SSD），无需进行碎片整理。“碎片整理”功能可以检测固态硬盘，让它们的健康状态维持得更久。
