Avira System Speedup is a Windows maintenance utility for cleaning unnecessary files, managing startup applications and adjusting how a PC uses its resources. It brings disk cleanup and performance controls into one application, with a free edition for basic maintenance and a paid Pro edition that adds automatic cleaning, deeper tuning and backup tools.
How Avira System Speedup manages startup
Avira System Speedup displays the applications that load when Windows starts. You can postpone a program or stop it from loading at startup, reducing the work that takes place before the desktop is ready.
Its startup monitoring also helps identify changes over time. Startup Guard sends a notification when startup takes longer, and the startup time notifier shows the duration. Hyper Boost, within the advanced tools, goes further by reducing startup applications and reorganizing the boot sequence and the loading of essential processes.
File cleanup
The cleaner scans for system caches, temporary files, internet leftovers and unnecessary user data. Removing these files reclaims storage occupied by disposable material. Browser cleanup also targets locally stored browsing traces and temporary online data across the browsers you use.
Exclusion lists give you control over material the cleanup should retain. They can contain individual files, registry keys, cookies and startup entries. For example, a cookie you want to keep can be excluded while other cleanup work continues; the listed items are ignored during the next cleanup.
Avira System Speedup Pro extends this work with tools for duplicate files and empty files. Its uninstaller removes unwanted software, while separate managers handle browser extensions and entries in Windows right-click menus.
Automatic cleaning
Pro can run cleanup on a weekly schedule. OnWatch provides a different trigger: it monitors the system and starts cleaning when accumulated junk reaches a threshold you choose. Alerts can also be customized.
The free edition covers essential cleaning and startup optimization. Advanced cleaning, deeper registry work and automatic optimization belong to Pro, along with the broader maintenance and restoration toolset.
Managing processes, services and power
Avira System Speedup Pro includes a process manager for viewing running processes and shutting down unnecessary ones. The service manager works with Windows services, allowing them to be started, stopped or uninstalled. A network traffic manager can close running programs connected to the internet.
For gaming, the software can disable unnecessary background processes to make their resources available to the game. Laptop controls offer a different choice: customizable Energy Saver, Power Boost and Balanced modes let you favor battery use, demanding tasks or a balance between them. Battery health information is available alongside these power settings.
Registry and disk defragmentation
Pro offers quick or deeper registry analysis, cleaning and defragmentation, as well as disk analysis and defragmentation. Disk defragmentation applies to non-SSD drives; Avira System Speedup does not defragment solid-state drives.
Backups, restore points and File Rescue
Pro includes backup controls for files and folders, the Windows registry and the master boot record. The MBR tool can also compare records to check for modifications.
Restoration controls can reverse changes made by System Speedup, including startup optimization changes, and manage Windows system restore points. A separate File Rescue tool searches for deleted files that can be recovered.
File privacy
The Pro privacy tools handle files you intend to keep or remove. File encryption password-protects important documents and includes decryption to access them again. File Shredder targets confidential files for permanent deletion, while Disk Wiper addresses an entire disk, such as storage being prepared for transfer to another owner.
