How to remove Scan Disk (Uninstall Instructions)

Don't Copy From This Blog...

Scan Disk is a fake defragmenter and system optimization tool. It is promoted through the use of trojans, fake online scanners and other malicious websites. It can be also distributed via facebook, twitter or other social networks. Basically, Scan Disk will infect your computer to make you think that you have some really serious problems, e.g. hard drive errors, corrupted memory, bad sectors and other stuff. Then this bogus program will try to make you buy its software to fix supposedly found errors and other computer problems. Do not fall victim to Scan Disk because it is nothing more but a rip-off rogue, scam. If you got this annoying program on your computer then please follow the removal instructions below to remove Scan Disk and any other related malware from your computer for free using legitimate anti-malware software.

A screen shot of Scan Disk

ScanDisk is clone of Ultra Defragger, Quick Defragmenter and HDD Defragmenter. As a typical scareware, it will pretend to scan your hard drives and memory for problems. Of course, it will find some critical hard drive and computer memory errors. By the way, it displays the same problems (11 errors) on each infected computer. How rude. Probably the biggest problem is that Scan Disk won't allow you to run other programs on your computer. It will state that this program is corrupted or cannot be found. The fake message reads:

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

However, if you attempt to run a program enough times it will eventually work. So, don't give up easily. After the fake scan it will display a list of errors:

Drive C initializing error
Bad sectors on hard drive or damaged file allocation table
Read time of hard drive clusters less than 500 ms
Hard drive doesn't respond to system commands

Furthermore, it will display fake alert from your Windows taskbar. Some of the fake alerts that you will see are:

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

Critical Error
Hard Drive not found. Missing hard drive.

Critical Error
Windows can't find hard disk space. Hard drive error
