Windows Ultra-Antivirus is a rogue anti-spyware program that displays false scan results, fake security warnings, and uses rootkits to prevent you from terminating or deleting the program. When installed it will be configured to start automatically when you login to Windows. Once started it performs a fake scan and then states that numerous files on your computer are infections. When you attempt to use the program to clean these infections, though, it states that you first need to purchase it before it will allow you to do so. As all of the infections are false, please ignore anything this program shows and instead continue with the rest of the removal guide.
While installed Windows Ultra-Antivirus will also display fake security alerts and warnings that are designed to make you think your computer is in trouble. An example of one of these warnings is:
Your computer is not checked for viruses! System scan is recommended. Press "scan" to check.
This infection will also display images of a hand juxtaposed over a warning symbol on your Windows desktop. These images and alerts are designed to scare you into thinking that there is a problem with the computer. Just like the scan results, all of these alerts are false and should be ignored.
Last, but not least, this rogue utilizes a rootkit to protect itself from being removed. Whenever Windows Ultra-Antivirus is started, the program will check if this rootkit is already installed. If it isn't, the rogue will install and activate it. The rootkit makes it so that you are unable to delete, terminate, or rename the main executable for the rogue program. If you remove the Registry entry that starts the rogue, the rootkit will also recreate it. Therefore, in order to properly remove this infection you must first remove the rootkit and then reboot into safe mode to remove the rogue program. This allows you to remove the infection without one of the components reinstalling the other one. The guide below will walk you through the proper steps to remove both the rootkit and the rogue anti-spyware program.
Without a doubt, Windows Ultra-Antivirus is a scam and uses malware to protect itself from being uninstalled. For no reason should you purchase this program, and if you have, you should contact your credit card company to dispute the charges stating that the program is a scam and a computer virus. To remove Windows Ultra-Antivirus and related malware, please follow the steps in the removal guide below.
Self Help Guide
- Print out these instructions as we will need to reboot your computer during this cleanup process.
- This infection includes a rootkit that protects the main executable for
from being terminated or removed. To remove this rootkit, we need to download TDSSKiller from the following link:
- Once the program is downloaded, double-click on it to start it. If Windows asks for your permission to allow the program to run, please allow it to do so. When you start TDSSKiller you may see a dialog appear that states that it Can't Load Driver. An example of this dialog is shown below.
This is to be expected with this infection and you can just press the OK button.
- TDSSKiller should now be started and you should click on the Start Scan button to begin scanning your computer for rootkits. When it has completed you will see a screen similar to the one below that states a locked service was found.
This locked service is the rootkit we need to remove.
- Click on the Skip menu, as shown by the blue arrow in the image above, and change it to Delete. Then click on the Continue button. At the next screen, TDSSKiller will state that it needs to reboot the computer to finish the deletion process. Before you click this button, please be aware that when TDSSKiller reboots your computer we need to go into Safe Mode with Networking instead of your normal Windows Login. Please familiarize with this tutorial to learn how to enter safe mode on your version of Windows.
- TDSSKiller will now reboot your computer, but instead of letting it go back into your normal Windows mode you must instead go into Safe Mode with Networking. To
do this, when your computer reboots and when you
see anything on the screen, start tapping the F8 key on your
keyboard. Eventually you will be brought to a menu similar to the one below:
Using the arrow keys on your keyboard, select Safe Mode with Networking and press Enter on your keyboard. If you are having trouble entering safe mode, then please use the following tutorial: How to start Windows in Safe Mode
Windows will now boot into safe mode with networking and prompt you to login as a user. Please login as the same user you were previously logged in with in the normal Windows mode. Then proceed with the rest of the steps. If you were unable to get into Safe Mode, then please try steps 3 through 7 until you are able to do so.
- At this point you should download Malwarebytes Anti-Malware, or MBAM, to scan your computer for any any infections or adware that may be present. Please download Malwarebytes from the following
location and save it to your desktop:
Malwarebytes Anti-Malware Download Link (Download page will open in a new window)
- Once downloaded, close all programs and Windows on your computer, including
- Double-click on the icon on your desktop named mbam-setup-bc.1878-18.104.22.1683.exe.
This will start the installation of MBAM onto your computer.
- When the installation begins, keep following the prompts in order to continue
with the installation process. Do not make any changes to default settings
and when the program has finished installing, make sure you leave Launch
Malwarebytes Anti-Malware checked. Then click on the Finish button. If MalwareBytes prompts you to reboot, please do not do so.
- MBAM will now start and you will be at the main screen as shown below.
Please click on the Scan Now button to start the scan. If there is an update available for Malwarebytes it will automatically download and install it before performing the scan.
- MBAM will now start scanning your computer for malware. This process can
take quite a while, so we suggest you do something else and periodically
check on the status of the scan to see when it is finished.
- When MBAM is finished scanning it will display a screen that displays any malware that it has detected. Please note that the infections found may be different
than what is shown in the image below due to the guide being updated for newer versions of MBAM.
You should now click on the Remove Selected button to remove all the seleted malware. MBAM will now delete all of the files and registry keys and add them to the programs quarantine. When removing the files, MBAM may require a reboot in order to remove some of them. If it displays a message stating that it needs to reboot, please allow it to do so. Once your computer has rebooted, and you are logged in, please continue with the rest of the steps.
- You can now exit the MBAM program.
- If after following these steps you are still having problems with this infection, then you should post a virus removal request using the steps
in the following topic so that you can get one-on-one help:
- As many rogues and other malware are installed through vulnerabilities found
in out-dated and insecure programs, it is strongly suggested that you use
Secunia PSI to scan for vulnerable programs on your computer. A tutorial on
how to use Secunia PSI to scan for vulnerable programs can be found here:

Your computer should now be free of the Windows Ultra-Antivirus program. If your current anti-virus solution let this infection through, you may want to consider purchasing the PRO version of Malwarebytes Anti-Malware to protect against these types of threats in the future.
