Windows Prime Accelerator is a rogue anti-spyware program from the Rogue.FakeVimes family of computer infections. This program is considered scareware because it displays false scan results, fake security warnings, and does not allow you to access your legitimate Windows applications. Windows Prime Accelerator is distributed through web sites that display a fake online virus scanner that states your computer is infected and then prompts you to download the installation file. This infection is also promoted by hacked web sites that contain exploit code that tries to install the infection on your computer without your permission or knowledge.

Once Windows Prime Accelerator is installed it will be configured to automatically start when you login to Windows. Once started, it will pretend to scan your computer and then states that there are numerous infections present. If you attempt to remove any of these supposed infections, the program will state that you first need to purchase a license before being allowed to do so. As all of the scan results are false, please ignore any prompts to purchase the program.

To protect itself from being removed, Windows Prime Accelerator will also block you from running any legitimate application on your computer. It does this to prevent you from running legitimate security software that may detect it as an infection and remove it. The message that you will see when you attempt to run a program is:

Firewall has blocked a program from accessing the Internet

Windows NT Logon Application
C:\Windows\system32\winlogon.exe

is suspected to have infected your PC.
This type of virus intercepts entered data and transmits them
to a remote server.

When you see this message please ignore it as your programs are not infected and will work normally after this infection is removed.

While Windows Prime Accelerator is running it will also display fake security alerts that are designed to make you think your computer has a severe security problem. Some of these warnings include:

Error
There's a suspicious software running on your PC. For more details, run a system file check.

Error
Trojan activity detected. System data security is at risk. It is recommended to activate protection and run a fully system scan.

Just like the scan results, these warnings are fake and can be ignored.

As you can see, this infection was created for the sole reason of scaring you into purchasing it. It goes without saying that you should definitely not purchase Windows Prime Accelerator, and if you already have, please contact your credit card company and dispute the charges stating that the program is a scam and a computer virus.

  2. For the first part of this removal guide you will need to use a different computer than the infected one in order to download and save some files that we need for the fix.

  3. On a clean computer, start a web browser and download and save the following Windows Registry file to your desktop from the link below:

    http://download.bleepingcomputer.com/reg/RemVimes.reg

  4. When the file has finished downloading, please burn it on to a CD or save it to a USB drive so that we can transfer the file to the infected computer.

  5. When you have finished saving the RemVimes.reg registry file to a removable media, please reboot the infected computer. While the computer is starting please being to repeatedly tap the F8 key on your keyboard. This will open up the Advanced Boot Options screen, in Windows 7 or Vista, or the Windows Advanced Options Menu in Windows XP. The screen that you need to get to will look similar to the one below.


    Advanced Boot Options

    At the above screen you will see a variety of options that can be used to boot Windows. Using the arrow keys on your keyboard, highlight the option labeled Safe Mode with Command Prompt. Once it is highlighted, click on the Enter key on your keyboard.

  6. Windows will now start and if you have multiple accounts or a password on your single account, you will be presented with a screen asking you to login to Windows. Please select your account and enter any password that you may have. When done, the Windows Command Prompt will open and you will see a screen similar to the one below.


    Safe Mode With Command Prompt

    The Command Prompt allows you to type commands and then press Enter on your keyboard to execute them. In this Command Prompt window, please type explorer.exe and then press Enter on your keyboard.

  7. The Windows desktop will now appear. When the desktop appears you can then close the Command Prompt window by clicking on the X.

  8. Now insert your CD or USB drive and open up the drive letter associated with your inserted media. You can access this drive letter by opening the Computer icon on your desktop or from the Start Menu. Once the drive letter is open, double-click on the RemVimes.reg and allow the data to be merged when you are prompted. Once the data has been merged, you can press the OK button and remove the removable media from your computer.

  9. Please reboot your computer into the normal Windows mode and login as the infected user. When you are back at your normal Windows desktop please continue with the next step.

  10. 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)

  11. Once downloaded, close all programs and Windows on your computer, including this one.

  12. Double-click on the icon on your desktop named mbam-setup.exe. This will start the installation of MBAM onto your computer.

  13. 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.

  14. MBAM will now start and you will be at the main screen as shown below.



    Malwarebytes Anti-Malware


    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.

  15. 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.



    Malwarebytes Anti-Malware


  16. 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.


    MalwareBytes Scan Results


    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.

  17. You can now exit the MBAM program.

  18. As this infection is known to be installed by vulnerabilities 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:
