Disk Optimizer

Although you may be led to believe otherwise, Disk Optimizer rogue defragmenter will destroy your PC from the inside out. The banefully insidious Disk Optimizer won’t take any prisoners in its attack against your system. It will simply stop at nothing to successfully achieve its main objective of ripping you off and leaving you with nothing but an empty shell for your hard earned money. Cloned from past successful rogues including Good Memory, Fast Disk and Disk Repair, it’s easy to see why the need to delete Disk Optimizer is palpable.

Disk Optimizer infiltrates its victim’s PC unsolicited, and will remain stealth on the system until it deems it the right time to reveal itself to the user. By this time the Disk Optimizer infection will have rooted itself on the system and the user will have h hard time to effectively get rid of Disk Optimizer. Spread via seditious Trojans caught from fake online malware scanners and bundled third party downloads, these Trojans exploit system vulnerabilities in order to keep their infiltration of the system as low-key as possible.

Disk Optimizer will present the user with various fake security alerts, which were designed explicitly with the aim of causing panic. Do not fall for these fake alerts, and never consider whatever they have to say as the truth. Some of the more notorious fake alerts to be on the lookout for include the following:

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.

There are many symptoms associated with a Disk Optimizer infection, and users who did not get rid of it in time complained about increased erratic system behavior and slow system performance. Another common occurrence shared by infected users cited them being unable to establish a successful connection to the Internet, as well as being unable to launch any executable files on the system. This is done in a concerted effort to prevent users from running or downloading a security application which can not only detect but ultimately erase Disk Optimizer from the system. If you want to reestablish your Internet connection and restore your ability to run executables, paste the following security key into Disk Optimizer:


Do not for any second think that the threat has been neutralized, as you still need to eliminate Disk Optimizer in order to eliminate the threat.

Do not underestimate the vitriol behind Disk Optimizer’s attack on the system. This rogue will simply not let up until it succeeds in its campaign or is removed. Invest in a properly functioning security application which will not only destroy Disk Optimizer but also offer future protection against similar attacks.
