Re: Malware Through a Router?

There are many ways besides windows networking that computers communicate over a LAN. It is possible for worms to spread if Windows networking is blocked.

Can malware be transferred to my computer from another computer using the same router?

Both computers are running Windows Vista Home Premium with a Linksys Router with WAP security.
Both computers connect to the internet, but I have not set up a network and we do not share any files.
Thanks, CB

Yes malware can travel between computers on the LAN behind the router. But if one computer is not sharing resources, like all the Windows Networking Ports are closed on a computer on the LAN, then no other computer on the LAN can communicate with the computer.

If the computer cannot communicate with other computers on the LAN, then it cannot be attacked by malware trying to populate itself from computers that are infected on the LAN.

You should be watching traffic to from the router, as that is a real threat with wireless, with someone attacking the LAN on the wireless or join your wireless network to exploit sites.
