Disk defrag and optimization improves performance and storage efficiency by re-organizing your hard disk drive to ensure that fragments of the same file are stored together.

Defragging is only recommended if you have an HDD (Hard Disk Drive). If you have a SSD (Solid State Drive), defragging is not necessary or beneficial. Avast Cleanup Premium automatically detects your drive type and only offers to defrag HDDs.

To check if Disk defragging is recommended, go to All functionsDefragment or optimize disks.

What is Disk Doctor?

Disk Doctor is a feature that scans for disk errors caused by corrupted areas on your internal and external drives, then offers to repair found issues. If left unrepaired, corrupted files can cause crashes, unexpected behavior, and loss of personal data.

To determine a program's rating, Avast Cleanup Premium uses a cloud-based rating system based on known blocked and allowed lists, heuristic algorithms, Avast's Recommendation Engine, and user ratings. This makes it easier for you to determine which programs you want to keep and which programs you want to remove.
