I plan on reformatting 2 computers on my wireless network that may be infected and there is a third computer on the network the user of which will not allow reformatting. If I clean those 2 is there any way to prevent being reinfected by the third computer when I connect back to the network? My wireless router has an A and a G network. Would keeping them on separate networks keep the other 2 safe?

Since the AP will more than likely bridge everyone on a common collision domain, the easiest way to reduce your risk exposure is by using a software firewall on each of your reformatted stations.

Or you can be a bit cruel and just change the access key to the Wi-Fi network (assuming you're running WPA or WPA2 via pre-shared key mechanism) and tell that owner of the third machine that until s/he sterilizes the machine with rubbing alcohol, soap, and various anti-malware software, he stays off your network. It's a bit tricky if he has physical access to your router and a spare Ethernet cable.]]> http://www.dslreports.com/forum/Re-Securing-shared-wireless-network-with-infected-PC-22326842 Fri, 01 May 2009 21:19:09 EDT http://www.dslreports.com/forum/Securing-shared-wireless-network-with-infected-PC-22326792 http://www.dslreports.com/forum/Securing-shared-wireless-network-with-infected-PC-22326792 Fri, 01 May 2009 21:06:26 EDT
