Ultra Defragger

Simply because the developers of well known rogues such as Quick Defragmenter or HDD Defragmenter decide to change the rogues’ names to Ultra Defragger, does not change or take away from these rogues’ vitriolic and malicious intentions. Ultra Defragger derives from both these infamous rogues and exceeds any previous efforts of this rogue family to achieve its devious goals.

Ultra Defragger has been exposed to be rogue defragmenter. As with its predecessors, Ultra Defragger is unable to detect and cure any real PC problems, and is only there to swindle money out of honest consumers. Ultra Defragger’s true colors appear shortly after the successful penetration of the PC, as the user will soon be bombarded with clearly fake popup notifications.

As is entirely expected, Ultra Defragger makes use of various fake notifications. Some of these reads as follows:

“System Restore
The system has been restored after a critical error. Data integrity and hard drive integrity verification required.”

“Critical Error!
Windows was unable to save all the data for the file System32496A8300. The data has been lost. This error may be caused by a failure of your computer hardware.”

These notifications should enjoy no attention, as they are blatant lies created solely to cause panic in the targeted victim. To remove Ultra Defragger, you will need the help of a properly functioning and powerful security tool unless you are confident with a manual removal. It is pivotal in the interest of promoting a secure and healthy PC that you always invest in keeping your genuine security software fully updated and up to date. This will allow for the tool to successfully eliminate Ultra Defragger and similar threats.
