I have wireless router here in my mother's house, I gave one cleaned laptop to my mom and my niece is using my mothers old laptop which i suspected infected with virus. The suspected laptop with virus is connected to the router by wired, the other laptop (clean) is connected wireless. I'm just curious if the cleaned laptop will be infected if they are using the same router? the cleaned laptop is protected by KIS, while the suspected "dirty" laptop is protected by unknown AV (it's like the fake AV logo) with Window firewall is OFF. thanks in advance.
