<< I can't get rid of nimda. I cleaned the 3 comps on my network with NAV 2002, and the removal tool from symantec, but FLTrack says it keeps comin back when I open word. Is there anyway to get rid of it? >>
YOu got to run the removal tool like 3 times. Run it; reboot; run again; reboot; run again...
Repeat until it comes up completely clean.
After that, if you've got boxes running unpatched IIS installations, they'll keep coming back. Also, one machine infected will continue to infect all unpatched machines in the network.
