How did SkyEmoji get on my computer?

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

How do I remove SkyEmoji?

Our program Malwarebytes Anti-Malware can detect and remove this potentially unwanted program.
  • 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 everything is set to "Quarantine", and click Apply Actions.
  • Reboot your computer if prompted.
Is there anything else I need to do to get rid of SkyEmoji?
  • No, Malwarebytes' Anti-Malware removes SkyEmoji completely.
  • You should be redirected to our Restore Browser page. You can read there how to fix additional browser redirect methods.
  • This PUP creates some scheduled tasks. You can read here how to check for and, if necessary, remove Scheduled Tasks.
How would the full version of Malwarebytes Anti-Malware help protect me?

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

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