I have some systems which are doubted to be infected with Trojan Win32/conficker. So I want to isolate those systems from locally accessing my other system in LAN to prevent trojan spreading. At the same time I want to allow the Internet access to remain open to the infected ones and all others also. I tried many combinations of rules but it is not happening. I have Dlink Di-524.

We are developing a website & its very urgent. So we can't put them off the Internet. I know I can run Windows malicious software removal tool. But the sytems' resources already overloaded due to the designing work. As a temporary remedy to stop the spread of trojan I want to change firewall settings & that too from Dlink di-524.
It is ok if they can't access themselves or any other computers in the LAN. We want Internet access only. Since other computers are also using Internet so the only way out is to keep these 2 systems off the LAN access. Due to some other reasons I am not preferring to block them by making changes to the firewall of all other systems by going to each machine, one by one.
