How to remove Disk Doctor (Removal Guide)

Tell your friends:
Disk Doctor is a fake disk defragmenter that deliberately reports false hard drive and registry errors. This rogue program is from the same family as HDD Scan, Win Defragmenter and Win HDD. This post is just for a record actually because all these programs are basically the same malware with many different names. There is nothing much new to say about Disk Doctor as it's an exactly copy of previous rogues from this family. While Disk Doctor is running, it will display a bunch of fake error messages and alerts like every on or two minutes saying that there is something wrong with your computer. It will report 11 critical errors after the fake scan which is super fast actually and takes only a few minutes.
  • Drive C initializing error
  • 32% of HDD space is unreadable
  • Read time of hard drive clusters less than 500 ms
  • Ram Temperature is 83 C. Optimization is required for normal operation.
  • Registry Error - Critical Error
  • GPU RAM temperature is critically high. Urgent RAM memory optimization is required to prevent system crash


What is more, the rogue program will terminate nearly all programs on your computer saying that there was some sort of hard drive disk error or something like that.
Windows detected a hard drive problem.
A hard drive error occurred while starting the application.
Windows cannot find notepad. Make sure you typed the name correctly, and then try again. To search for a file, click the Start button, and then click Search.
It will probably make your Desktop background black and hide some of your icons. Disk Doctor messes up with Windows folders too. You may see all the files from Programs Files directory in My Documents folder or in any other folder. If you got hit with this piece of malware then you should follow the removal instructions below to remove Disk Doctor and any related malware from your computer for free using legitimate anti-malware software. Last, but not least, if you have already purchased it then please contact your credit card provider and dispute the charges.
