How did Coupoon get on my computer?

Adware applications use different methods for distributing themselves. This particular one was bundled with other software.

How do I remove Coupoon?

Our program Malwarebytes Anti-Malware can detect and remove this potentially unwanted program.
Please use their own uninstaller first, but I would advise to follow the steps below anyway.
  • Please download Malwarebytes Anti-Malware to your desktop.
  • Double-click mbam-setup-version.exe and follow the prompts to install the program.
  • At the end, be sure a check-mark is placed next to the following:
    • Enable free trial of Malwarebytes Anti-Malware Premium
    • Launch Malwarebytes Anti-Malware
  • Then click Finish.
  • If an update is found, you will be prompted to download and install the latest version.
  • Once the program has loaded, select Scan Now. Or select the Threat Scan from the Scan menu.
  • When the scan is complete, make sure that all Threats are selected, and click Remove Selected.
  • Restart your computer when prompted to do so.
Is there anything else I need to do to get rid of Coupoon?
  • No, together with the uninstaller, Malwarebytes' Anti-Malware removes Coupoon completely.
How would the full version of Malwarebytes Anti-Malware help protect me?

We hope our application and this guide have helped you eradicate this hijacker.

As you can see below the full version of Malwarebytes Anti-Malware would have protected you against the Coupoon adware. �It would have warned you before the rogue could install itself, giving you a chance to stop it before it became too late.
