How To: Remove HDD Diagnostic Malware / Virus ( Removal Guide )

by Vlad Andrici on December 9, 2010


HDD Diagnostic is a rogue ( malware, virus, however you want to call it ) parading as a system optimizer software that, once installed, tries to convince users there is something wrong with their system by displaying various fake error messages.

HDD Diagnostic is installed via Trojans or the TDSS Rootkit ( aka Google Redirect Virus ). Don’t worry, this removal guide will also show you how to get rid of the TDSS Rootkit.

Once installed, HDD Diagnostic will start every time you log into Windows and it will display error messages when the user tries to launch any program or delete files. It will then ask you to analyze your system with the program and, if you do that, it will display numerous warnings and errors that can only be fixed if…surprise, surprise…you buy the full version of HDD Diagnostic. Of course this is a scam so don’t be tricked into giving your credit card info.

How To: Remove HDD Diagnostic Malware / Virus ( Removal Guide )

First of all, if you’re experimenting Google redirects ( search result links are redirected to unrelated sites ), you find yourself unable to access various web sites or web browsing is slower than normal, your PC might be infected with the TDSS Rootkit. If so, check out this nice TDSS Rootkit removal guide.

Actually you might want to browse that guide first anyway just to make sure you don’t have HDD Diagnostic on top of the TDSS Rootkit.

HDD Diagnostic Removal Guide

Before starting to deal with HDD Diagnostic you need to download iExplore.exe and Malwarebytes’ Anti-Malware to your computer.

If HDD Diagnostic prevents you from downloading files, you need to get them on an uninfected system and transfer them via USB, CD/DVD etc.

  1. Launch iExplore.exe in order to stop all the processes associated with HDD Diagnostic. It might take a while but you’ll know that iExplore has finished when the black window disappears.
  2. Note: You might receive some messages saying that iExplore.exe is a virus. Don’t worry, this is just HDD Diagnostic’s way of defending itself. If such a message appears leave it on the screen and run iExplore.exe again. If you’re still having problems download RKill.com and/or eXplorer.exe from the provided link and try again ( they are just renamed copies of iExplore.exe )

  3. Execute the downloaded MBAM ( Malwarebytes’ Anti-Malware ) setup file and complete the installation following the on-screen instructions ( just make sure that both “Update Malwarebytes’ Anti-Malware” and “Launch Malwarebytes’ Anti-Malware” boxes are checked ).
  4. Attention ! Don’t reboot your system even if MBAM prompts you to as you’ll have to start over.

  5. Once the installation finishes MBAM will automatically start. Select Scanner, then Perform full scan and click Scan. The scanning process might take a while.
  6. When the scan finishes click on Show Results, make sure every box is selected and then hit the Remove Selected button. Good Job!

You can now restart your system as HDD Diagnostic should be removed by now.

      Hi Callum,

      No, you don’t have to buy MBAM. The shareware version works just fine.
