DioCleaner is a rogue anti-spyware program that may be secretly installed on your system. DioCleaner will intentionally seek to trick you into buying the “full version” of the software by issuing fake security notifications. DioCleaner will display a pop-up advertisement or a balloon on your system tray claiming that your computer is infected with spyware. DioCleaner may be secretly installed through nefarious Trojans, drive-by downloads or via other unsolicited delivery methods. DioCleaner may also appear very difficult to remove manually because of its ability to recreate itself. DioCleaner is an extremely dangerous threat and shouldn’t remain in your computer system.
