Removal of JS:Miner-AI[PUP]

Question

When I try to access every site without using HTTPS. I get a popup from avast telling me they have blocked it.

It says 'JS:Miner-AI[PUP]'. When I try to access google.com (without https) it happens as well.

I have tried the following:

Scan with Avast, adaware and Malwarebytes (used to remove previous versions of js:miner)

Does anyone have any suggestions on what I can do to remove it?

Answer 1

Turns out that the router was infected. Once the router was replaced the problem was solved.
