Subject: Jefferson-Is this a known problem? Trojans?

I haven't heard of this message before, however, many messages such as these have header info generated ("brand spoofing"), which thus varies the sender/subject lines from message to message.

The first thing I would do when my system boots back up is check Task Manager for currently running processes on the system.  Anything peculiar should be checked out.  You should also perform a port-scan, if you have the tools, to make sure there haven't been any ports opened up that are running an unwanted service.

There are tools, such as Ad-aware that can be used to scan for malware on your Windows system (www.ad-aware.com).  Symantec and others are helpful, but only for known viruses.

Of course, the best cure is to not open emails from unexpected sources, but if you must, at least open them in "text only", as this may reduce the risk involved, especially if this becomes an ongoing problem.

If a re-install is needed, just be sure to start the firewall before attaching it to a network and make note of all the processes that run by default, so you will always know exactly what should be running on your system. One thing they teach you in SANS courses is that if you don't know what's running on your system and what your network and CPU load is on an average day . . . how will you ever know if your systems been breeched.
