If your XP firewall is not blocking oubound connections, or is allowing
inbound connections for your IIS web server, then you may be vulnerable to
various threats. There are various trojans that allow remote access, and/or
email passwords to a hacker's email address, and/or capture the keystrokes
that you type [including your posting, and passwords, etc.] and email them
to a hacker or capture them to a text file.

The book incident response is a good introduction to dealing with these
things. fport from www.foundstone.com can help, as can NETSTAT -AN. If you
are running IIS, find and look at your IIS log files, if they exist. Look
for any line mentioning .EXE or % and if a code 200 or 502 is mentioned in
that line, this could be suspicious. Also, downloading pstools from
www.sysinternals.com includes the command psloggedon which tells you who is
logged into your system at the moment. If your XP firewall includes any
logging, check the logs for anything unusual. If questions, post them here.
Running an antivirus or trojan scanner that has the latest daily updates can
help detect trojans, and running www.gfi.com languard file integrity checker
daily can detect suspicious file changes.
