Hi David

Possibly lop.com (IIRC). This site is notorious for modifiying registry settings, plus WWW related files to point to 
pr0n and other sites of dubious reputation. Don't go to lop without all scripting etc disabled in the browser.

Subject: Unknown Hosts file




I have a client machine running Windows 2000 
Professional.  All of a sudden, one day, the user was 
unable to access several of the most popular 
websites (i.e. google, yahoo, cnn, etc.).  I noticed that 
the machine was attempting to access the wrong IP 
address for all the websites, in fact, it was attempting 
to access the SAME IP address for every website in 
the group.  After some research, I found there was a 
Hosts file with all the domains in question listed, and 
the erroneous IP address.  Has anyone ever come 
accross an incident where a virus or trojan would 
place a Hosts file onto a system.  I have thoroughly 
scanned the machine for viruses, open ports, etc. 
and found nothing.  Is there anything else I should be 
on the lookout for?
