Is Mighty Text a trash product?

Hello @,
 
Welcome to the Webroot Community,
 
I can't say if Mighty Text is a bad product. Is Mighty Text installed as an extention in your browser? If its in Chrome follow this below.
 
Go to Chrome menu --> Tools --> Extensions, find the MightyText add-on and click on the Trashcan icon next to it to remove it.
 
Have you tried uninstalling from the Control Panel/Programs/Add Remove?
 
One other option is to use Revo uninstaller.
Revo Uninstaller  Information and Download

• Third Party Utility  Included even though a third party utility due to recommendation.  Free and fuller featured pro versions available, this utility helps remove stubborn remnants standard uninstalls can leave behind. 

Hope this helps,
 
Kind Regards,
