hi, I read your reply.
The fact that there are so many sites that checks the dns vulnerability including hijacks. I have tried more sites and the result is that the same is in good condition, particularly when I change the dns to 1.1.1.1 in the concerned devices.
The fact the dns is the gateway through which you do all your browsing and subsequent activities, and it will not be kind of aspirin problem. It is more risky than that.
So, only I asked the query if it is false positive .
I have strong password for my router. Only thing is that I do know how to configure bb router, but somewhat lack the knowledge to configure fibre brand. So, I change dns in the devices set up, in ipv4 and ipv6.
I do online transactions and so, I was bothered about this dns hijack probability on my router and network.
Hope that some from avast would give a reply to this thread
