DiskClean (Disk Clean) is a rogue security tool. DiskClean spreads via Trojans and once it is inside a computer system it will create a registry entry that will ensure it is executed with every system reboot. DiskClean will bombard a victim with fake security alerts and scan reports claiming that the system is infected and the only solution is to purchase the "full version" of DiskClean. DiskClean is created to swindle gullible users who believe the fake security notifications and purchase the rogueware. DiskClean should be removed upon detection.
