This guide is for a new Trojan.Tech-Support-Scam that displays a fake Windows Product Key verification prompt instead of your normal Windows desktop. This prompt will state that malicious software was detected and that you need to reenter your product key in order to verify you have a licensed copy of Windows. In this screen will also be buttons that open the TeamViewer, Supremo, and Logmein sites as well as a button called CMD that opens the command prompt. Last, but not least, the screen will display the phone number 1-844-459-8882, which is for a remote tech support company that will state they are Microsoft and try to sell you unecessary support services.
This fake Product Key screen is displayed by replacing your Windows Shell configuration so that it executes the malware program instead of your standard desktop. The text of this fake Product Key verification alert is:
Product Key Customer Support: 1-844-459-8882
Your computer is suspected of malicious software, for the purpose of verification enter your windows product key. You will find your product key on the box that Windows Dvd came in or in the welcome email or on the certificate of authenticity stick.
It looks similar to this: XXXXX-XXXXX-XXXXX-XXXXX-XXXXX
If you are infected with this Trojan, you may be able to unlock the screen and remove it by entering the qwert-yuiop-asdfg-hjklz-xcvbn key into the product key field and pressing submit. If that does not work, then please use the guide below instead.
How did the fake Windows Product Key verification screen get on my computer?
It is important to note that the the Product Key scam is bundled with and installed by free programs that did not adequately disclose that other software would be installed along with it. Therefore, it is important that you pay close attention to license agreements and installation screens when installing anything off of the Internet. If an installation screen offers you Custom or Advanced installation options, it is a good idea to select these as they will typically disclose what other 3rd party software will also be installed. Furthermore, If the license agreement or installation screens state that they are going to install a toolbar or other unwanted adware, it is advised that you immediately cancel the install and not use the free software.
As you can see, this Trojan is a complete scam that is designed to scare you into thinking there is something wrong with your computer so that you call the listed phone number. For no reason should you call this number and buy services, and if you have, you should contact your credit card company and dispute the charges. Please use this guide to remove all remnants of the Product Key tech support scam from your computer for free.

Before using this guide, we suggest that you read it once and download all necessary tools to your desktop. After doing so, please print this page as you may need to close your browser window or reboot your computer.
As Fake Windows Product Key Screen Scam makes it so you are unable to acces your Windows desktop, you need to open the Windows Task Manager from the Windows Security screen. To do this, press the CTRL+ALT+DEL 
keys on your keyboard at the same time to display the Windows Security Screen as shown below.
At this screen, click on the Task Manager option to start the Windows Task Manager.
You will now be at the Task Manager screen as shown below. If you are in Windows 10, you will need to click on the More Details option and the screen will look a little different. Make sure you are in the processes tab and search for the Productkeyupdate.exe or fatalerror.exe process in the list of processes.
When you have found the process click on it once to select and then click on the End Process button in Windows 7 or the End Task button in Windows 10. The process should now be terminated. Do not close the Task Manager window, though, as we need it for the next step.
Now that the process has been terminated we want to start the Windows Explorer. Most of the time this will cause the Windows desktop to appear, but if not, you will at least be presented with a My Computer folder that you can to navigate the file system and launch applications.
In Task Manager, click on the File menu option and then click on Run. You will now be at the Run dialog as shown in the image below.
In the Open: field, type explorer.exe and then press the OK button.
Your normal desktop should now appear and you can continue with the rest of the instructions. If the desktop does not appear, then a My Computer window will open that will allow you to navigate the file system to launch programs or delete files.
We now need to download a batch file that will remove the Shell registry configuration that is loading the ProductKey malware.
To do this, open Internet Explorer from the Windows Start Menu. If you are not able to see your desktop, then you can navigate to the C:\Program Files (x86)\Internet Explorer folder and double-click on the iexplore.exe file.
Internet Explorer should now be open and you should go to this link: http://download.bleepingcomputer.com/bats/clean-hkcushell.bat. When you visit this link, it will prompt you to save the clean-hkcushell.bat file.
Please save this file on your computer and double-click on it when it has finished downloading. This will run a batch file that will clear the Shell configuration that loads the malware file instead of your desktop. When it prompts if you wish to delete the key, press Y and then enter on your keyboard.
Next time you reboot your Windows desktop will appear as normal and you can continue with the rest of the instructions.
As Fake Windows Product Key Screen Scam sometimes has a usable Uninstall entry that can be used to remove the program, we want to try that first. To do this, click on the Start button and then select Control Panel.
When in the Control Panel, double-click on one of the options below depending on your version of Windows
- For Windows XP double-click on the Add or Remove Programs icon.

To terminate any programs that may interfere with the removal process we must first download the Rkill program.

If you have problems running RKill, you can download the other renamed versions of RKill from the rkill download page. All of the files are renamed copies of RKill, which you can try instead. Please note that the download page will open in a new browser window or tab.
Do not reboot your computer after running RKill as the malware programs will start again.

To remove the adware programs that were detected in the previous step, please click on the Clean button on the AdwCleaner screen. AdwCleaner will now prompt you to save any open files or data as the program will need to close any open programs before it starts to clean.
