Can a virus pass through lan?

[↑↑↓↓←→←→BASelect]

I just built all 4 of my kids and wife a new pc for chirstmas. If they get a virus on there pc can it be transfered to my pc? The 4 kids will be using wifi and my wife will be hard wired. I didn't set up home network sharing. So we can't share files between computers. But can a virus/malware/trojan/what ever else i forgot to metion infect my pc from theirs.

you wont be able to get a virus/malware/trojan any infectious thing from there pc from the internet as long as you dont download or vist the website you should be fine and a fine way of avoiding a situation for viruses is using a VM virtual machine at times but no need to as long as you know how to avoid downloading them and stuff use something like virustotal for inspecting websites files on your pc if you really dont know if its safe.

I know all about how to avoid getting infected i also told my kids. But you know kids in one ear and out the other and end up going to a site that their friends told them about. So i was just wondering using same internet connecting to same router can spread stuff. Kinda like in an office building.

As long as you don't have a central NAS or use windows sharing functions you should be alright.

OK thats what i figured but wasn't really sure.

Theoretically, yes. But it would require massive security issues on the Operating System.
As long as you keep those up to date, nothing should spread on itself through your local network.

Since most NAS'es use some kind of *nix based OS you should be fine either way. I'm assuming the computers will run Windows and Windows viruses can't infect anything *nix based. So, your comment regarding a NAS doesnt make much sense t.b.h..

Also, u can get infected by malware nowadays by just browsing a website that has malicious code hidden in advertising banners which uses for example flash that wasn't recently patched by you, or simple contains another exploit not even patched by Adobe. Most cryptolocker misery works like that nowadays. No more downloading and running an executable manually to get a virus, just loading a website that hosts these banner containing malicious code can cause you to no longer have access to any of your files.
The only way of having this crap not spread is to make sure that all the pc's are patched/updated and keep getting patched (most importantly things like java and flash - so browser plugins), use up to date virusscanners on all of em and make sure you don't do any file swapping amongst them using Windows shares for example. If you are not sharing data amongst them and the only thing they share is a network cable to the router to provide em with internet access, you should be fine. Another good practise is to make sure to use a username and a password to logon on every computer aswell. And most def. not use the same username and password amongst different computers, as this might allow a virus/malware to see if theres any other computers on the network it might want to try to access to infect.

Yes all 5 of their pc's are locked with their own password.Well to be fair i let my wife chose her own. Shouldn't have a problem with ad banners giving viruses i installed firefox with ad block plus the one i have been using for years and never seen an ad since.

use ublock, umatrix - it better, than adblock

It's not possible to rule it out, but it would probably make the news if anything were successfully attacking up-to-date systems via the default network services. This is the sort of thing that gets OS vendors to issue emergency hotfixes. As others have said, infection via hacking a website to exploit the web browser/plugins is the preferred vector now.
