Slashee_the_Cow, I forwarded your text (about security) to the person. his answer:
"He is partly right, but there are many BUTs.
Now computers in 90% of cases are behind the provider's NAT + are behind the router's NAT, so it is unrealistic to get to the computer from the outside, for a direct attack you need a white IP and the Internet is connected directly to the computer, or there is a vulnerability in the router through which you can access the local network.
Viruses like those in the 2000s are no longer made by anyone, why waste time, now it's either miners or advertisers. Miners have not worked on XP for many years, advertisers may lie somewhere old ones that work, but I think there are few of them left either. The share of XP users is less than that of Linux, making compatibility with it no longer makes sense. Now the user installs almost all the infection himself, when he downloads all sorts of activators from left sites, pumping up online games, does not disable the checkboxes in the installers, no updates will help here, they often bring Win10 stuffed with advertising programs or miners. By the way, the built-in defender 10 does not protect against them in any way. wannacry was the last major attack that worked on XP, and only on computers connected directly to the Internet. After it, holes were found in the hardware, but without updating the BIOS, they cannot be completely closed. And you can still install Kaspersky 19 on XP, it receives database updates, and you can install a free one. And to prevent infections from getting in from the outside, install a good firewall, configure it to block all incoming connections, and then the protection will be complete. But you need to install an antivirus and a firewall on any OS if the computer is connected directly to the Internet, because sometimes updates are released after the vulnerability has been exploited."
