System Check is yet another malicious malware product that has been introduced to the Web by the same family of rogue anti-spyware applications that are responsible for System Fix and Data Repair. Hailing from a very large and incredibly dangerous family of rogue defragmenting tools, System Check is an absolutely bogus and useless fake computer analysis and optimization program that is out to scam and rob unsuspecting computer users. System Check convinces computer users that there is something seriously wrong with their computer systems.

The System Check Scam-Art

As a rogue defragmenter, System Check will definitely work to convince you that it is a legitimate defragmenting application. This malicious program possesses a convincing outer shell and works to emulate the real functionality and inner workings of authentic, legitimate defragmenting software. System Check was created and designed by cybercriminals to be especially convincing in its false pretense of legitimacy, because much of this scam relies on System Check's ability to convince you that it is a real computer defragmenting program.

The System Check scam works by running fake system scans on infected machines and concluding these bogus scans with equally phony error detections. Fake detections that the System Check scans claim to have found on compromised machines always claim to have discovered all kinds of hard drive-related problems.

This is why System Check's attempts to convince you that it is a legitimate defragmenting application is so central to its scam. This rogue defragmenter needs to convince you that there is definitely something severely wrong with your system's hard drive, and in order to do this successfully, it needs you to genuinely trust in its bogus and non-existent air of authenticity.

Additionally, System Check will work to create a flood of pop-up error alerts on your infected computer system, and these alerts will bare messages meant to reiterate the false claims made by this malicious defragmenter's fake scans and detections. Such messages may appear on your desktop, as follows:

System Error
An error occurred while reading system files. Run a system diagnostic utility to check your hard disk drive for errors.

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

Critical Error!
Damaged hard drive clusters detected. Private Data is at risk.

System Check is a Malicious and Dangerous Rogue Deframenter

As is hopefully clear from this discussion of System Check, this entire malware-laced cyber scam heavily relies on methods of trickery and manipulation to achieve its end-game of convincing its unlucky victims to purchase the full version of the bogus System Check defragmenting application. System Check also relies heavily on its internal scareware mechanisms that are designed to frighten you into believing its lies.

Do not allow System Check to dupe you into purchasing its useless and entirely bogus computer defragmenting software. As a rogue defragmenter, System Check cannot offer any real, helpful or useful services to you or your computer system.

In fact, this rogue defragmenter is a dangerous malware product that is capable of seriously threatening not only your pocketbook, but also your vulnerable computer system. If you suspect that this program has been able to breach your system successfully, in hopes of severely compromising it, it is very important that you take the necessary steps to remove this harmful rogue defragmenter program from your infected machine completely.
