Hey there, I'm Tim, what do you mean by uninstall it? It simply needs to be unplugged and have the network forgotten in windows.
So its a system file thats running, it may need to uninstalled manually.
you can try uninstalling it in safe mode, you can get to safe mode by rebooting and as soon as the system starts up keep striking the f8 key, and then select safe mode from the menu
depending on how its set up, i might just try and disable it in start up, or services.....as well as delete the files that are there, it almost sounds like it did a partial uninstall.
