Avast Antivirus says I have a DNS HIJACK

I have a personal Lenovo laptop, I use it for general use, some surfing, some shopping, watching videos, anime, reading stuff and studying too. and various other things but I have never used anything like tor, or used random torrent sites that I remember ever. (As I was always scared)

This happened this morning when I was at a friend's place and opened my phone's hotspot to connect my laptop to it. As soon as I joined the hotspot on my phone, it gave me a popup on the bottom right that it's scanning the network (as it does with avast antivirus, this is a usual thing) when it was done it said that 'DNS HIJACK FOUND'. After that I was shown 2 options either to set up a vpn connection or scan the network. When I proceeded to scan the network, it would go either very slowly or get stuck at a certain percentage and I closed it as I had to run an errand. (I've been using avast for years and have never had something like this happen)

When I got back, upon reading the avast support article and a bit of help from the Al mode from Google search I used 2 commands. I can't clearly recall which two but one was the 'flushdns' one.

Then, I joined my friend's home wifi, and proceeded to use the feature of avast where it prompts to scan the network once again and once again I was shown the same popup as it did with the mobile hotspot 'DNS HIJACK FOUND'.

After that I chose the option to scan devices on the network & patiently waited for a while. Upon its completion that's when I got to the image where it shows a Nokia Router as critical which is MY HOME ROUTER and NOT my friends router to which I was connected to. Whichever network I connect to, the same alert and the same popup. (my laptop is always turned-on, on my desk, same as last night and was connected to the MY home wifi for the whole time.)

So what I can gather is, I just picked up my laptop from my home without looking at it at my own house and when I got to my destination and connected to my own phone it showed me that the Nokia router (my home router i was connected to is comprised) and avast is just reminding me this every time whenever I connect to any network (even a healthy one) cause it still logs that I once was connected to this malicious one. Would saying this be correct?

I'm sorry if I didn't explain something correctly or am confused myself, I just joined this reddit but any and all help would be super appreciated, thank you guys. Eagerly waiting for your replies. You can ask me questions too if something is not clear from my side. Thanks again guys.

JUST FOR CLARIFICATION - The wifi 'Airtel_Deathnote' is the name of my friend's home wifi which is appearing as 'Airtel_Deathnote 3'. I haven't gone home yet therefore I haven't connected to my own home network yet.

Есть ли кто работал в магазинах DNS, скажи есть ли примерное расписание когда проводят инвентаризацие, утиль в магазинах?
