Utility Software

1. System optimisation

   • Defragmentation: puts files that are broken back together. Moves all files to allow free space
   • System clean up: scans and removes files no longer needed
   • Compression software: reduces sizes of files to free up space
     • Example: .zip and .rar

2. Back up programs

   • Backup utilities: stores files and settings externally
   • Full backup = copy of every file is taken
   • Incremental backup = only files created or edited since last backup are taken

3. Security software

   • Encryption software: scrambles data to stop third parties from accessing it
   • Anti-virus software
   • Firewall
   • Spyware detectors: block and delete programs designed to collect personal information
