Help with Exploit

Hello List,

We're experiencing a serious problem on our networking with an exploit. After running the Microsoft rootkit detector we found the following:

Key name contains embedded nulls (*),8/13/2001 12:06,0
Key name contains embedded nulls (*),8/13/2001 12:06,0
Key name contains embedded nulls (*),3/24/2005 11:56,0
Hidden from Windows API.,1/31/2007 15:25,13.00
Hidden from Windows API.,1/31/2007 16:32,7.50
Hidden from Windows API.,1/31/2007 16:32,9.50
Hidden from Windows API.,1/31/2007 16:32,12.50

Did some research on the pfplgflt.dll files and found this:

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.
