I have had several cases where a virus has inadvertantly got into one pc on a network, eg the Antivirus XP 2009 trojan. Once in, it clearly opens up the PC to other malware, and then spreads to other PCs within the network, in a couple of cases the routers have also become infected.
Getting rid is not a problem, however trying to curtail the spread is stumping me somewhat. I thought I could control via static IP addresses but I can’t think of a good piece of software to control this aspect.
It doesn’t appear to matter what antivirus the guys have, Norton, McAfee, Bullguard, AVG systems have all been successfully attacked.
Most of these “soho” systems rely an a standard AV out of the box and windows XP firewall, and the firewall built into the routers, typically netgear dg834g/gt/pn/n or linksys wag160n, various Belkin models, etc.
Any ideas of software that could block lets say one pc so that other PCs could block any comms from a particular PC within a system – eg a child using the same internet connection on his/her lappie, as say another PC used for business?
Suggestions would be welcome
