    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.

    I suggest that you treat the network at your mom's home like a public wifi hot spot, which means no network sharing and firewall configured as directly connected to the internet.

    Now that malware is inside the network what is possible?

    • Banker Trojans
    • DNS Changer Trojans
    • Router Malware
    • Install Trojan Router Software (Embedded OS that router uses) that looks legitimate

    • Metasploit

    aka "Don't trust it". This is my greatest concern, that one of the computers in my house gets a problem and uses the LAN to spread. I have a lot of stuff sharing wise going on in my house, and I don't want to make uber tight settings with firewalls etc for it. Therefore I try my best to ensure nothing gets through in the first place.

    Bottom line, it is very hard to trust a local machine on a local network if any virii etc have been found. Already mentioned, act as if it is a public hotspot. Better yet, get rid of the problems and make sure they don't come back. I would reformat and reinstall if that ever happens to me.

    Why take a chance at all? I would definitely reformat and reinstall the infected machine asap, as Sully has suggested. That's the best option IMO.
