Why does your device slow down over time?

You started off with a blazing fast device. Now… it’s… so… slow you want to take a shower while you wait. Here are the main culprits:

Heavy software baggage

From new games to the latest updates, users tend to accumulate more and more on their devices. Plus, updated apps demand better, bigger hardware to run and hog your resources.

Too many start-up items and tasks

It’s convenient when Skype, Dropbox, OneDrive, and co. show up in your task bar when you boot up, but adding more and more items slows you down.

Cluttered hard drivE

Over time it becomes packed with unnecessary stuff such as temp files, traces of your internet surfing, and unnecessary user data.

Poor maintenance

Many devices don’t get the regular clear-out and tune-up they need to perform at their peak. Poor things.

System Speedup for Windows

Discover an industry leader for more stable, turbo performance:

Helps you “lose weight”: Rids your system of all the clutter it no longer needs (system cache, temp files, internet junk, duplicates, etc.).

Tidies up your browser: Removes all online traces and temporary data from every browser to declutter your machine and shield your privacy.

Cleans your registry: Invalid registry entries? Remnants of uninstalled software? System Speedup analyzes the problems and clears them out.

Avira Antivirus Security for Android

The free Android app equips you with antivirus protection, a VPN, and a host of tune-up utilities:

Performance optimization: Improve app and system performance, increase your browsing speed, and reduce lag.

RAM optimization: Our RAM cleaner optimizes your RAM, ending unnecessary processes to improve your device’s performance and prevent overheating.

Storage optimization: Rid your device and SD card from cache, junk, and duplicate files — and free up space for things that matter more to you.

Worried about maintaining your device? Relax.

We hope you have more on your mind than device optimization—that’s why we created OnWatch for PCs and Macs. Use it to schedule automatic alerts to clean your device.

Discover System Speedup ProFor Windows

Avira System Speedup includes many free tuning tools to clean your Windows laptop of junk files and other useless data, making it run faster. Plus, the freeware optimization tools also help your laptop start much more quickly. On top of that, removing unused apps and files or archiving them in the cloud or on an external drive means you can speed up your laptop and free up storage space you didn’t know you had.

Junk data builds up in your PC over time, causing it to slow down. This junk includes temporary and duplicate files, invalid registry entries, and the leftovers of any software you’ve uninstalled. All this throttles your PC’s performance, causing it to slow to a crawl as well as crash and become unresponsive. And because a whole host of apps all try to start simultaneously when you turn on your PC, it takes longer to start. Avira System Speedup is packed with loads of free optimization tools, helping you clear away junk files and useless data, speed up your PC, and make it start faster.
