Crashing network

I am living in a place currently with a crashing network.

If a computer on a network is acting as a zombie can it crash its parent network? I ask because on of the network users seems to have a virus on his computer and this could explain our bizar network issue.

As you can tell I have exhausted many of the less dramatic causes and am grasping somewhat.

Hi themadjester!

What exactly do you mean by a "crashing network"? Can you describe what happens and what you have tried in more detail? And what kind of network is this?

Generally speaking if only one computer is infected, it won't (although possible) make the network as a whole malfunction. But this can be different in specific cases.

Is there a reason you have not tried to quarantine that one computer then check if the fault persist? this would be standard procedure if you believe that one computer is causing issues

also what makes you believe that one computer has a virus?

also as above we will need more description of the fault and also the type of network, Windows / MAC / Wired / Wireless

Well, things seem to be sorted out. The one fellow likely has a computer full of virus but thats his fault and his problem.

The reason I could not isolate his computer was that the router is a shared thing in this building and coincidentally kept in a place were he cnstantly has access to it so cutting him off for long enough to definitibly know he was the cause would be impossible.

The solution? (well for everyone else except virus guy) the solution was a different router. Now this really confused me because when the network went down I would troubleshoot and try to isolate the router as the cause (since it was the 1st thing that came to mind). I would power cycle the modem and plug my computer into it and still get no signal so I really felt that this must be a modem/cable network/ZOMG were getting disconnected by the ISP for spamming or soemthing.

But in the end shitty router [seems to] explain all.
