I said there won't be any traffic. I won't browse the internet, but I will use the PC for hosting a server for Counter-Strike. No internet browsing, no downloading files - but only hosting the server.if you on a unsupported os. there might be security issue that let attacker do stuff on the pc.
it is a two way street. your pc is going to process the incoming traffic.
use something like glasswire to look at that. not sure if the buildin firewall tell you anything
If the PC doesn't receive any traffic in the form of cookies, cache, browser extensions, downloading files, receiving requests, etc..., can it still get viruses?
In short, if I connect the PC to the internet, and then put the game server files on it, start the server, and never use the PC for anything else rather than hosting the game server, could the PC still get viruses?
