Data cleanup tools can help your computer run smoothly and prevent it from picking up harmful or unnecessary files, such as trackers. They can also clean out your personal data, such as your internet history, to reduce the risk of it falling into the wrong hands. Free tools will generally get the job done, but they have to be configured and run manually, which can take time. Instead, consider an app that runs automatically in the background. This type of service often has bonus features such as keeping your drivers updated in addition to keeping your computer clean, so it can be exceptionally useful.
