There are a couple of methods you could employ to determine whether or
not this is a problem:
1. Monitor the network using tcpdump, ethereal or other monitoring tool
and shut down all non-necessary services on this host. If you see
suspicious traffic, this might indicate who or where it is going to so
you can validate it and/or the contents.
2. Use the sysinternals tools from Microsoft to discover who is doing
what on your server:
download from:
http://www.microsoft.com/technet/sysinternals/default.mspx
One problem here is that if it's malicious code at work you're defending
hosts when you should be defending your network(s). Find out where the
problem is coming from and shut it down at the firewall.

Did some research on the pfplgflt.dll files and found this:
http://vil.nai.com/vil/content/v_122073.htm
All of the files and registry settings listed on the McAfee site were
found on the system, and also a strange a.exe file. Found some general
info about the a.exe file, but all of it was useless and did not relate
at all to this exploit IMHO. I guess it uses a.exe just because. The
boxes had the latest AV updates and engines, and also the latest OS
updates (Windows 2000). Even worst, after reinstalling one of the
boxes, and updating to the latest everything once more, the box was
infected once more. I am know trying to find a way to end this email
with a "professional" sounding question, but to be honest, I don't know
how to proceed with this one. Please help!
Thanks in advance.
Vic
