Users should be aware of the scam criminal developers are running with the rogue system optimizer Defragmenter. This now infamous rogue has been determined to emanate from the very same family such as well known and highly despised rogues Smart HDD, HDD Rescue and Ultra Defragger. These reasons alone are more than enough inspiration why users have to get rid of Defragmenter before it does permanent and irreversible damage to their systems.

As with most any rogue security tool, Defragmenter will want the user to believe that his PC is either under attack from Internet viruses, or that his system has already been compromised. Defragmenter will go about doing this by making use of various fake security notifications in an effort to create panic in the user. Some of the more notorious notifications to be on the lookout for includes:

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

“Windows detected a hard drive problem.
A hard drive error occurred while starting the application.”

Obviously none of these notifications can be trusted. Users who did not get rid of Defragmenter in time have reported on various distressing and disturbing symptoms, including being unable to connect to the Internet, blocked access to their Desktop, increased system erratic behaviour and dramatically slowed system performance.

In order to effectively eliminate Defragmenter from your system you’ll need the removal power of a powerful security tool. Invest in an application which will be able to eradicate Defragmenter and offer protection against future threats.
