Ccleaner – Steroid Enhanced Cleanup
Everything we do on a computer leaves some sort of temporary file behind. Browsers cache all of their content to speed up delivery of frequently used web pages. Often these temporary files can become corrupted by shutting down the computer with an application or browser is still open. Windows has a built-in cleaner called Disk Cleanup, but often it still leaves a lot of files behind, especially for some applications. CCleaner is Disk Cleanup on steroids.
