basically this
The "security" guys and "updooters" probably don't even know basics about networking and just regurgitate something that companies and other businesses want people to think. It's not bad per se, because most people are tech illiterate, but it's plainly not the whole truth and every one in the know knows it.
It's clearly in their best interest that people fear a boogeyman so they buy new hardware, update their software, buy new bloated versions that sucks more, does everything or less, does that x times more inefficiently, is less accessible, breaks the user workflow and looks like dogshit.
Yes, you can get a virus that will do something to your computer if you download a sketchy file and run it, but that's what AV were for if you don't have Common Sense™. They will quarantine the file instantly. There is more chance to download a false positive if the user is not retarded.
Nowadays the user only need to use an up to date browser, use an adblocker and don't fall for retarded scams like you are 1_000_000 visitor and you have been chosen for whatever reward.
The ISPs make problems even if you want to use another router than theirs, they would never allow anyone to connect their pc directly to the internet. It's just retarded. Every internet user in civilized country is protected by firewall by default.
