Omega AntiVir is classified as a rogue anti-spyware application because it displays false and exaggerated results as a method to have you purchase the software. When installed Omega AntiVir will be configured to start automatically when you log into Windows. Once running it will perform a scan and then state that there are numerous infections found on your computer, but will not remove them until you purchase the program. These supposed infections, though, are either legitimate programs or do not even exist on the computer. The reason Omega AntiVir displays them is to make you think you are infected in the hopes that you will then purchase the program.

Automated Removal Instructions for Omega AntiVir 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.

  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 Omega AntiVir 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:
