Smart Defragmenter

Trojans are responsible for spreading the sophisticated yet harmful rogue known as Smart Defragmenter. It will block legitimate system executables and claim that they Disk is inaccessible, with plenty of errors. This is the first point of attack from Smart Defragmenter. It will continue to keep your PC ransom until you eradicate Smart Defragmenter from your system.

Smart Defragmenter will report on errors affecting the hard disk, RAM memory and the registry. Its one goal is to convince the PC owner of its legitimacy, so that it can make a successful sale of its worthless software. Users should be aware that should their PC’s memory or HDD be corrupted, it is impossible to fix with a third party software application, something Smart Defragmenter dutifully neglects to inform its intended victims about. Smart Defragmenter is a very complicated and sophisticated scam, offering proactive data protection which it simply is not able to.

Users who receive any of the following should already be suspicious and on the lookout for more symptoms of a Smart Defragmenter infection:

“Critical Error!
Damaged hard drive clusters detected. Private data is at risk.”

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

“Critical Error
Hard Drive not found. Missing hard drive.”

These are only some of the many fake security messages Smart Defragmenter employs to convince users of its legitimacy. It is completely ridiculous, as some of these notifications report on your PC running without a hard drive. Yet many consumers and PC owners still fall for these absurd notifications.

There is no benefit to Smart Defragmenter, and users are urged never to pay for any product related to Smart Defragmenter. To limit the damage done to your system, simply stop Smart Defragmenter by eliminating it for good.
