How to remove Check Disk (Uninstall Guide)

Tell your friends:
Check Disk is a rogue hard drive disk defragmenter and system optimization program that pretends to scan your hard drive disks, registry and system memory for errors. It reports a variety of bogus errors and displays fake messages to scare you into thinking that your computer has some serious problems. Check Disk blocks other programs on your computer and prompts to pay for a full version of the program to remove non-existent computer errors. Do not purchase this rogue program. If your computer is infected with CheckDisk malware then please follow the removal instructions below.

Check Disk is promoted through the use of trojans and other malicious software, e.g. fake/infected web pages. The authors of the rogue program may also promote it on Facebook, Twitter and other social networks. Once installed, Check Disk will pretend to scan your computer for errors. The scan won't take long. After the fake scan it will report 11 errors and recommend system defragmentation. In Windows XP and Windows Vista it will display fake safe mode screen if you choose to defragment your hard drive. The rogue program won't display the fake safe mode screen if you use Windows 7. That's probably the main difference. Some of the fake computer errors Check Disk detects:
Requested registry access is not allowed. Registry defragmentation required
Read time of hard drive clusters less than 500 ms
Bad sectors on hard drive or damaged file allocation table
Drive C initializing error
Hard drive doesn't respond to system commands
Data Safety Problem. System integrity is at risk.
Registry Error - Critical Error
Furthermore, CheckDisk will block nearly all programs on your computer and display the following error message:
Windows detected a hard drive problem.
A hard drive error occurred while starting the application.

If you attempt to run a program enough times it will eventually work. Last, but least, Check Disk will display fake errors messages and pop ups from your Windows taskbar. The text of some of the alerts you may see include:
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.
System Restore
The system has been restored after a critical error. Data integrity and hard drive integrity verification required.
Check Disk is from the same family as Ultra Defragger and HDD Defragmenter.
Without a doubt, you can not trust this program. It's a scam. You should contact your credit card provider and dispute the charges or even cancel your credit card if you have already purchased Check Disk. Then please follow the removal instructions below to remove Check Disk and related malware from your computer using legitimate anti-malware software.

If it works, the rogue program won't block malware removal tools and other programs making the removal procedure a bit easier.
