Ultra Defragger is the updated version of fake computer optimization programs Quick Defragmenter or HDD Defragmenter. This new variant of malicious defragmenter, just like the earlier ones, will never report real computer problems because it is designed to swindle the money from trustful PC users. Just after its secret intrusion done with a help of Trojans, Ultra Defragger starts showing its fake notifications and pop-up ads that all can be clearly predicted to make you concerned about your machine. Never believe this fake useless defragmenter and instead of falling into its invented information given, remove Ultra Defragger!

Similarly to its above mentioned predecessors, Ultra Defragger reaches the system without user permission and in order to protect itself attempts to disable legit antivirus software found. Targeted PC becomes completely taken over by this scam in the result of such actions and Ultra Defragger begins the campaign it was designed to. UltraDefragger will keep launching at startup, so be sure it will greatly affect your computer by running fake scanners and pop-up ads or notifications that will annoy you to death. It will also block other programs that are important for a normal computer’s work, like Notepad. On these alerts you will be seeing various phony system errors that are important to be ignored, for example:

Windows detected a hard drive problem.
A hard drive error occurred while starting the application.
Windows cannot find notepad. Make sure you typed the name correctly, and then try again. To search for a file, click the Start button, and then click Search.
Requested registry access is not allowed. Registry defragmentation required

    Before you download the spyware, note the “For free scan” and dont waste your time. It will only scan unless you pay for it. It will not remove your malware. If youre going to remove it manually, write down what filename was randomly selected before you start deleting.
