ScreenshotQuick Defrag or QuickDefrag is a fake system optimization program advertised on rogue websites and distributed by sneaky Trojans. Quick Defrag is from the same family as HDD Tools and they both use fake system scanners and pop-up alerts to convince victims that their systems are riddled with dangerous errors.

The errors typically involve the hard drive and CPU claiming that they cannot be detected or the temperature is extremely high. Fortunately, the error reports or alerts generated by Quick Defrag are false and never to be trusted. Users that encounter Quick Defrag, and any of its fake security alerts, should have this rogue removed immediately with an effective anti-rogueware tool.
