Well, I have installed that Advanced IP Scanner and it turns out that it's a Dell thing. I have no idea how it got on my PC. Now, how do I delete or un-install it?

You cannot. It is a network device that possibly Windows thinks that the MAC ID on it is a Dell Computer or a network device that Dell brands. Possible that that chipset or group of MAC ID numbers were used by Dell for some of the brands that they had purchased and then rebaged the name.

Find the IP with that Hostname and then go into your Gateway to see if it is in the IP Table. That will also mean going to every device in your home to find out which one has that MAC ID. As long as the device is connected to your network, it will always appear in Windows as a device that is connected. Not much that you can do just because of the name of the device. I would not really get up tight when it may be as I stated above. If your network is secure and no one can get in from the outside, every device is clean, just move on at this point.
