I have a very recent build of XP Pro with SP2, all updates, Firefox 3.08 w/NoScript, Sandboxie, Google Earth, latest Wireshark, latest Nmap, Comcast's version of McAffe Security Center, TCPView, Process Explorer, latest Thunderbird. Machine is on its own IP behind a Netscreen 5XP. I just recently noticed the VC_RED.cab and its files while looking around in Windows Explorer. I know for sure that it wasn't there upon completion of the new ground-up rebuild. Any feedback would be appreciated.
