Previous Versions:
Ultra Defragger comes from the same family of rogues that includes Smart Defragmenter and HDD Defragmenter.
What it Does:
Ultra Defragger will bombard your computer with numerous fake system alerts and scans in an attempt to lure you into purchasing the full version, which is nothing more than a hoax as Ultra Defragger is not legitimate software and is actually a spyare infection. Ultra Defragger can also hijack your web browser and redirect your search results to pages of its choosing, where you will likely encounter more fake alerts and system related warnings.
The larger threat that Ultra Defragger poses however, is that it can download and install keyloggers and other more severe malware that can log your keystrokes, websites visited, etc. and can send that information over the internet to a remote server where the hacker that created Ultra Defragger will then use that information in an attempt to gain access to your credit cards, bank accounts, and numerous other sensitive personal information – and may ultimately end up stealing your identity.

***Please note we highly recommend not attempting manual removal of Ultra Defragger unless are a trained computer professional. Ultra Defragger is a highly complex and dynamic spyware infection that can hide several random files throughout your computer’s registry and file system and makes manual removal almost impossible. In addition, deleting and modifying system files and your computer’s registry wihout proper knowledge and training can cause further issues and may even cause your computer to become inoperable. As such, proceeding with manual removal is done at your own risk and spyware-experts.com cannot be held responsible for any problems that may occur in doing so.***

Important:
Note that even if you have followed all the above steps and performed the tasks correctly, it is highly probable that Ultra Defragger will remain on your computer and continue to cause problems. The reason for this is that the program is dynamic and can change the filenames, locations, etc. and can even add additional infected files while it is on your computer.
This is why we highly recommend an automatic detection and removal tool such as Spyware Doctor that can find these additional hidden files and ensure that Ultra Defragger is completely removed from your computer.
