Check Disk

It would seem as though the seemingly genuine looking Check Disk application is nothing more than a rogue optimization and analysis program, out to fleece honest consumers out of their hard earned money. Employing the very same scare tactics as with most other rogueware, Check Disk will make use of false information which it will present to its prospective victim, in an effort to panic him into thinking there’s something wrong with his PC.

Once Check Disk is installed on the PC, its configuration will allow it to start up automatically whenever Windows starts. While running, Check Disk will display various fake error messages whenever the user attempts to execute legitimate executables or when trying to uninstall a program. The user will then be prompted to scan his PC with Check Disk, which will inform the user of many errors which will remain unfixed until the paid version of Check Disk is purchased.

If the user is to make use of the “Defragment tool,” it will inform the user that it needs to be run in Safe Mode. A fake Safe Mode background will then appear which is only employed as to further fool the user. In a further attempt to convince the user of its lies Check Disk will make use of various grave looking security notifications. These notifications are fake and should enjoy no attention from the user. Some of these notifications reads as follows:

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

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

Check Disk will eventually make it impossible for the user to launch any executable on his PC, in essence rendering the PC completely unusable and worthless. Users should never fall for this type of scareware blackmail, and are urgently advised to completely eradicate Check Disk off their systems. This can be done by making use of the removal power of genuine security software which are able to effectively delete Check Disk.
