Avast blocking access to websites and applications - HTML:Script-inf infection

Viruses and worms
1

Looked through the answer on earlier threads:
https://forum.avast.com/index.php?topic=222230.0

However, after every operation or click to navigate to a certain website, I am presented with the alert for infection.
I have run full system scan on avast and also downloaded malwarebytes anti-malware as suggested in the “logs to assist in cleaning malware”.

I am unable to convert the reports into .txt file as there is no export option.

Is this a false positive? I am unable to visit websites without hitting refresh multiple times.

Attaching the other screenshot - which I couldn’t attach due to size in the earlier post.

Also - I am not necessarily visiting all the websites mentioned below in the screenshot.

e.g. I don’t even know what fotkica.com is. Other websites that I haven’t even tried accessing that can be seen in the list below is - apple.com.

What else can be used for a Mac?
Are Avira, Sophos, Bitdefender any better? Scanned using all of them. None of them detected this infection. :-X

This is most probably a MitM attack - something along the way is injecting malicious code to every webpage you are trying to visit. The most common cause is infected MikroTik router, but it could be another agent as well.
