We have scanned EECS subnets, with supplied tools, for Conficker infected hosts with negative results. We continue to scan but users should follow the instructions from US-CERT on all Windows hosts including those at home.
US-CERT encourages users to prevent a Conficker infection by ensuring all systems have the MS08-067 patch (part of Security Update KB958644, which was published by Miscrosoft in October 2008), disabling AutoRun functionality and maintaining up-to-date anti-virus software.
