Unexplained Threat Alerts

I keep receiving alerts while browsing online that a “HTML:RedirME-inf[Trj]” infection is being blocked.
I have since run a full system scan and a boot time scan of all my partitions, a full system scan with Malwarebytes, deleted my cache and cookies and reinstalled Avast… To completely no avail.

Can anyone help me with this?

Cheers,

Here we go

Can you post just a picture of the Avast alert?

Also, please remove ALL the cracked / pirated software from the system. We will need to get fresh logs after that and then see what can be done.
