If you are an EE customer, you should really have been directed to the EE forum however......
I have presumed you are using Avast on a PC or Laptop.
If you don't use Skype why don't you just uninstall it from your device.
Is it the free version of Avast or do you pay for it?
If it is the free version a recent update has probably triggered its "upgrade scaremongering" into action.
For information, every Internet connection get repeatedly scanned by hackers hoping to fined a way into peoples private networks. This is prevented by your routers Firewall and is nothing to worry about.
The update will have activated "network scanning" and this in turn has picked up "avastui.exe which ironically is an Avast product.
See link.

The other network that has been picked up will most likely be the free EEWifi hotspot which was formally known as BTWifi.
You can go into Avast settings by clicking on the "Menu" at the right hand side and in the "Protection" section "Network Inspector" and turn off/untick "Scan New Networks Automatically" and "Re-Scan Networks Automatically".
You can also click on the "Protection" button on the left hand side and go to "Network Inspector" then check that your BT hub connection is selected and is showing "Scan this Network" beside it.
The network class should be shown as "Home" and the Firewall profile shown as "Trusted".
If you do the above you can still manually start a network scan at any time and I would suggest that you do that on a weekly basis for piece of mind. You can do that by clicking on "Protection" and then "Network Inspector" then "Scan This Network".
