If your router is handing out IP addresses using DHCP then it might also
hand out DNS entries. That would explain why your /etc/resolv.conf keeps
being overwritten.
AFAICS you have two options:
1. Make sure your router (DHCP server) knows of the DNS you want to
use.
2. Add a script to get your DCHP client to add the DNS entries you
want. (If you use dhcp3-client then you should take a look at
/etc/dhcp3/dhclient-*-hooks.d/.)

Most people, I think, don't even know what a Rootkit is, so why should
they care about it?
