Ultra Defragger is a fake optimization tool which claims to provide proactive data protection. Ultra Defragger spreads by using Trojans to block legitimate software programs. This rogue program also produces popup warnings claiming that the disk is inaccessible and has lots of errors. The message falsely reports that ram memory is in danger of being lost and that the registry is under threat as well. The corrupt program will then urge unwary computer users to purchase a copy of Ultra Defragger to repair the system. Ultra Defragger poses a severe threat to PC security and should be removed before it starts wreaking havoc in the system.
