I had a question about security on my network.

I just found out that another computer (a PC) on my network has like 40 Trojans on it. Could that computer have sent my Mac a virus on my network?

Also, do all the computers on my network share the same IP address (or share anything for that matter)? Thanks.

Thanks!!

They share the same range of IP addresses.

For example, they may all be in the range of 192.168.1.x where x is a number from 1 - 254. When one host wants to talk to another one that is in the same range as itself, it sends traffic directly to that host. If a host tries to connect to something not in the same range as itself, such as www.macrumors.com (64.62.137.66), it sends the traffic to your router (the "default gateway") to be sent out across the Internet.
