Quick Defrag

It would seem as though the developers behind rogue defragmenters are putting in much more effort into the aesthetic appeal of their products, in an effort to con their targets more successfully. Quick Defrag, which hails from the same cist pool as Smart Defragmenter, HDD Defragmenter and System Defragmenter is a rogue system optimizer unable to live up to any of its over embellished promises. As with any rogueware product, Quick Defrag one and only goal is to fleece its victim out of as much money in the littlest amount of time. Quick Defrag has no intention of benefiting any infected system, and will stop at nothing to successfully accomplish its main objective, even if it means being responsible for irreversible damage to its victims’ PCs.

Quick Defrag makes use of established modes of infection, making use of fake system scanners and illicit browser hijackers. These browser hijackers lures unsuspecting Internet surfers to its site, then exploits browser and system vulnerabilities in an effort to forcefully deliver the Quick Defrag Trojan to the system. Legitimate security updates and codecs obtained from third party websites may also carry Quick Defrag Trojans and malware infections, and remains a popular way for Quick Defrag to infect its victims’ systems.

This rogue not only resembles its contemporaries in its Graphical User Interfaces, but builds on their already harmful attack to deliver a crippling attack on its victims’ PCs. Its presence on any system is so volatile, and as soon as you notice it on your PC you will want to get rid of Quick Defrag immediately.

Quick Defrag will not ask the PC owner’s permission before entering his PC. The forced intrusion is heralded by modifications made to the system’s Registry, which dictates that the compromised Operating System will execute the malware’s executable whenever the PC boots up. As a first line of attack on the system, Quick Defrag will assail the PC owner with a tremendous amount of fake security alerts, which warns of dramatic infections ravaging the system. These fake security notifications read as follows:

“Requested registry access is not allowed. Registry defragmentation required
Read time of hard drive clusters less than 500 ms
32% of HDD space is unreadable
Bad sectors on hard drive or damaged file allocation table
GPU RAM temperature is critically high. Urgent RAM memory optimization is required to prevent system crash
Drive C initializing error
Ram Temperature is 83 C. Optimization is required for normal operation.
Hard drive doesn’t respond to system commands
Data Safety Problem. System integrity is at risk.
Registry Error – Critical Error”

“System Error!
Exe file is corrupted and can’t be run. Hard drive scan required.
Scan Hard Drive”

“Safe Mode required
Boot into Windows Safe Mode required
Boot into Windows Safe Mode required to get into defragmentation module. The safe mode is needed for effective problems fixing. The process takes as little as 10 minutes. Once the process has been completed, the safe mode will be automatically turned off.”

Quick Defrag will then recommend that the PC owner install ‘powerful’ software to solve these issues, which means the consumer will have to fork out money and pay for Quick Defrag’s recalcitrant software first. Users infected with Quick Defragmenter will also find that they will not be able to launch any programs on their system. This is done in an effort to prevent the user from running a security application which could detect and remove Quick Defrag from the system. The following security messages will be displayed each time a user tries to launch an executable.

“Windows cannot find ‘winword’. Make sure you typed the name correctly, and then try again. To search for a file, click the Start button, and then click Search.”

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

Some of these fake alerts will also appear from the Windows task bar, reporting about more system errors:

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

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

“Critical Error
RAM memory usage is critically high. RAM memory failure.”

“Critical Error
Windows can’t find hard disk space. Hard drive error”

“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.”

“Critical Error
A critical error has occurred while indexing data stored on hard drive. System restart required.”

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

It is clear to see through these extortionary measures that Quick Defrag is not a legitimate application, and that no correspondence received from it can be trusted. Users suspecting their system of being compromised by this outlandish rogue need to get rid of Quick Defrag before it damage their systems irrevocably. If attempting to manually remove Quick Defrag, users should search for the following processes and stop tGldgRksm.exe and 1584321.exe.

Do not become this rogue’s next victim. Obliterate Quick Defrag from the PC as soon as it’s detected. Do not waste another minute and leave your PC compromised, vulnerable and unprotected. Invest in a properly functioning security tool which will not only erase Quick Defrag from the system, but also offer future protection against similar threats and attacks.
