a linux virus: NetworkManager

[Pierre Frenkiel]

I was doing some internet browsing in firefox, and suddenly,
the network stopped working. I immediatly suspected the NetworkManager:
I had removed it from Intrepid, but it has been re-installed with Karmic.
I removed again the package, and killed the runnind daemon: still no network, or more
precisely no DNS. I then discovered that this bastard had replaced my /etc/resolv.conf 
by an empty one!
After restoring the good resolv.conf, the DNS started again to work...
Can anybody explain this behavior of NetworkManager?
