You need some type of virus scanning or you will NEVER remove Nimda.... If
you don't clean the machines, it doesn't go away by itself...

Yes. I have a 2948G-L3.
The virus is being spread by disk sharing.
I have a big amount of machines here and talking to Mcafee wouldn't be a
good idea($$). It would be better to solve this through the 2949G-L3, if
possible.
