Scammer’s Number: N/A, since the pop-up only wants you to download some rogue AV. Haven’t checked that out, because of no virtual machine 
Domains Used: bbcc.co.uk / bbbc.co.uk (redirects to: " McAfee Total Security (aprmbscan.xyz)"
Extra Info:
If you click “Proceed” it takes you to the real McAfee site to download and pay for the real McAfee anti virus. This is a scamming affiliate and McAfee refuse to stop the scamming affiliates which makes McAfee complicit in this scam.
[ McAfee Total Security (securepc-now.com) ]
Another website. Redirects from “allowsuccess.org”. If you click on “Allow notifications” to supposedly prove that you’re human - you’ll be constantly getting annoying popups claiming that you’re infected and if you click, you’ll be redirected either to McAfee, or Norton.
