what is a btt.balloon.dll?

recently i have recovered my laptop (studio 1747, win 7, 64 bit) from a virus and after a brief period of time I realized that there was a missing operation or program called a btt.balloon.dll and I'm wondering what is this program and how do I recover it again?

Hi roguestatus,

The bt.balloon.dll is related to the Bluetooth software. I suggest you to reinstall the Bluetooth drivers and application from the following link by entering the Service Tag and selecting the version of Windows:

Please let me know if you need further assistance.

I'm not sure where else to look under driver and downloads, i downloaded the dell application under networks, but other than that I'm not sure what else would be bluetooth related.

Hi roguestatus,

Thank you for your reply and for providing an update on the status. Please provide a screenshot of the devices listed in Device Manager and the version of Windows, so that I can provide the appropriate driver and application.

I just searched my system for bt.balloon.dll and it's located at...


C:\Program Files\WIDCOMM\Bluetooth Software


Please follow the instructions that is providing.


You may have to download the bluetooth drivers and save them to your desktop. Go to Drivers & Downloads enter your service tag, then select your operating system. Under network, download the bluetooth drivers and save them to your desktop.


Make a system restore point. You can try my suggestion below. If it doesn't work, you can come back to what you have.

Start, control panel, device manager. Under network adapter, right click on your bluetooth adapter, left click uninstall. Tell it to remove the drivers and software.


Navigate to C:\Program Files\ and you may have to delete the WIDCOMM folder.


Restart your computer.


When you log in, the new hardware wizard will try to install your device. Install the drivers save to your desktop.


What happens?
