Today, for the first time, *.0.0.0.0 appeared in my Internet Explorer 6
Trusted Sites list - without my having added it. Even after I remove it
from the trusted sites list, it reappears the next time I invoke the trusted
site dialog.

My questions are: 1) Is this spyware; how else could be happening? 2) How
volunerable does it make me? 3) How can I remove this address from my
trusted sites permanently?

TIA.
