Avira Free System Speedup

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.

Optimizer for Mac

Fire up the app, do a scan, and see it remove the clutter that’s slowing you down.

Does a spring clean: The Junk File Cleaner deletes unnecessary files and browser junk. The Duplicate Finder clears copies of photos and other files.

Gets rid of monsters and dinosaurs: It spots XL and old files that are hogging your resources.

Speeds up start times. Helps you speed up by around 25%, as it limits the number of tasks performed while Windows loads.

Optimizer for Android

Turn even an older Android into a lean, mean mobile machine.

Boosts speed: Optimizes processes for faster start-ups and greater performance.

Cleans up fast: Clears your cache junk and duplicate files on your phone and SD card for a feather-light, speedier experience.
