I have this exact same problem. I am running windows 10 pro. I have removed Norton (previously supplied by BT protect) and also run the mcafee MCPR tool. However when I select the Manage button on the mybt Security>Your Security>BT Virus protect screen it redirects to the Mcafee page shown above? There is no button to click or a download starting. I also notice the mybt site still referrs to McAfee in various places.
Can you advise please?
I tried clearing cache and cookies but the same result. The mcafee window that pops up, has correct details from when I was running it before Norton replaced it a year or so ago?
Any other pointers?
