In order to uninstall the program you can use the Add or Remove Programs feature. For this, you need to go to Start > Control Panel > Programs > Programs and Features. Select the application and click on Uninstall. If this doesn't work, you can force it to uninstall using Revo Uninstaller.
After that, try running AdwCleaner to make sure that there are no leftover rogue registry keys or toolbars in your system.
