Alpha Antivirus is a rogue anti-spyware program from the same family as Personal Antivirus. This program is promoted through the use of malware and web pop-ups that will be displayed as you browse the web. If you are infected via a malware infection, then Alpha Antivirus will be installed onto your computer without your knowledge or permission. If you encounter it via a pop-up, you will see a prompt stating that your computer is infected. When you click on this prompt you will be brought to a page showing an advertisement that pretends to be an online anti-malware scanner. This advertisement will pretend to scan your computer and then state that there are infections and that you should download and install Alpha Antivirus to protect yourself.

When Alpha Antivirus is installed it will be configured to start automatically when you boot into Windows. Once running it will perform a scan of your computer and when finished state that there are numerous infections on your computer. It will not allow you to remove these infections, though, until you first purchase the program. These infections are all fake and do not exist on your computer. They are only being shown to scare you into purchasing Alpha Antivirus.

There are a total of 3 images you can view.


While the program is running you will see a constant barrage of fake security alerts and windows. These alerts, like the fake scan results, are designed to make you think there is a security risk on your computer and then suggest that you purchase Alpha Antivirus in order to protect your computer. Just like the scan results, these fake alerts are all fake and the only infection is Alpha Antivirus and the malware that was installed alongside it.

If you are infected with Alpha Antivirus, then please do not purchase this program. If you have already purchased it, then we advise you to contact your credit card company and dispute the charges as this program is a scam. Last, but not least, please use the guide below to remove Alpha Antivirus and related malware from your computer.

Automated Removal Instructions for Alpha Antivirus using Malwarebytes Anti-Malware:

  1. Print out these instructions as we will need to close every window that is open later in the fix.

  2. 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)

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

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

  5. 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.

  6. 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.

  7. 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

  8. 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 listed 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.

  9. You can now exit the MBAM program.

Your computer should now be free of the AlphaAntivirus 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.

If you are still having problems with your computer after completing these instructions, then please follow the steps outlined in the topic linked below:
