Disk Doctor - How to remove

Disk Doctor is a name used by many services, apps, and programs. A few of those are malicious or potentially unwanted. Such as the obscure fake optimizer called Disk Doctor and the Disk Doctor Pro by FIPLAB.

In this post, we’ll discuss these apps, what problems they might cause and how to remove them. However, keep in mind that not all programs and services called “Disk Doctor” are malicious. Each one needs to be considered separately.

About Disk Doctor:

Threat type	Potentially unwanted program.
Disk Doctor for Windows	Promoted by fake virus alerts, shows fake error messages and causes system instability.
Disk Doctor Pro for Mac	Promoted by online ads, offers redundant features.
How to remove Disk Doctor	Uninstall it manually, use security programs, such as Spyhunter for Windows or Malwarebytes.

Disk Doctor for Windows

Disk Doctor was an old Windows optimizer – or rather, a fake system optimizer. It was a close sibling of the infamous Win Defrag, Scan Disk, and Win Defragmenter.

Disk Doctor was distributed to computers by Trojan viruses which show fake virus alerts and error messages. These alerts are meant to convince you that your computer is in danger and needs a program like Disk Doctor to save it.

Once Disk Doctor is installed, it scans your computer and reports tons of critical errors. In addition, it shows various fake disk errors, messes with other programs, makes folders look empty, and generally causes chaos. It could be considered scareware as it tries to make the user feel scared for their computer.

Here are some examples of the errors that the Disk Doctor malware displays:

Critical Error!
Windows was unable to save all the data for the file \System32\496A8300. The data has been lost. This error may be caused by a failure of your computer hardware.

Critical Error
A critical error has occurred while indexing data stored on hard drive. System restart required.

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

Requested registry access is not allowed. Registry defragmentation required
Drive C initializing error
Read time of hard drive clusters less than 500 ms
32% of HDD space is unreadable
Bad sectors on hard drive or damaged file allocation table
GPU RAM temperature is critically high. Urgent RAM memory optimization is required to prevent system crash
Ram Temperature is 83 C. Optimization is required for normal operation.
Hard drive doesn’t respond to system commands
Data Safety Problem. System integrity is at risk.
Registry Error – Critical Error

All of these messages and scan results are meant to make you purchase the full version of Disk Doctor. Supposedly, it will solve all the problems that appeared on your computer. You must ignore any of such statements and instead remove Disk Doctor from your computer as soon as possible. Never pay for this noxious application as you will only lose your money, time, and privacy. In case this has already happened, contact your credit card and dispute the charges immediately.

Luckily, this Disk Doctor program is quite old and likely not being spread anymore. But it’s possible that some versions of it can still be downloaded from the web.

Disk Doctor Pro for Mac

Another questionable app that uses the Disk Doctor name is a Mac optimizer by FIPLAB. It’s a modern app, unlike the Disk Doctor described in the previous section.

Disk Doctor Pro offers to clean your Mac by finding and deleting unnecessary files: caches, downloads, logs, screenshots.

Unfortunately, Disk Doctor Pro is considered to be a potentially unwanted program. This is because of a few problems:

• The limited free trial could pressure users to buy the full version of the app.
• The Uninstall and Refund information isn’t displayed prominently.

Besides, Mac doesn’t need optimizer apps. Apple offers a variety of free tools to help users optimize storage space on their Macs. Apps like Disk Doctor Pro are redundant.

How to remove Disk Doctor malware

You can uninstall these programs. Windows and macOS instructions can be found below.

For getting rid of the Windows version of the Disk Doctor virus, it is also helpful to use an antivirus program, such as Spyhunter. Scan your device and delete all the suspicious programs and files.

On the other hand, the Disk Doctor Pro app for Mac is hardly detected by scanners at all. It’s not malicious like the Disk Doctor malware above. You can use a sensitive anti-malware app like Malwarebytes to review your Mac and remove potentially unwanted items.

Automatic Malware removal tools

How to remove Disk Doctor using Windows Control Panel

Many hijackers and adware like Disk Doctor Pro install some of their components as regular Windows programs as well as additional software. This part of malware can be uninstalled from the Control Panel. To access it, do the following.

• Start→Control Panel (older Windows) or press Windows Key→Search and enter Control Panel and then press Enter (Windows 8, Windows 10).
• Choose Uninstall Program (if you don't see it, click in the upper right next to "View by" and select Category).
• Go through the list of programs and select entries related to Disk Doctor . You can click on "Name" or "Installed On" to reorder your programs and make Disk Doctor Pro easier to find.
• Click the Uninstall button. If you're asked if you really want to remove the program, click Yes.
• In many cases anti-malware programs are better at detecting related parasites, thus I recommend installing Spyhunter to identify other programs that might be a part of this infection.
