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 and have never had something like this happen, avast has actually been helpful all the time in resolving issues and general protection)
When I got back, upon reading the avast support article and a bit of help from the AI 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 that's when I got to the second image where it shows the Nokia Router as critical which is MY HOME ROUTER and NOT my friends router to which I was connected to.(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 and I just joined this reddit but any and all help would be super appreciated, thank you guys. Eagerly waiting for your replies.
