Actually, I don't think it sounds a damn thing like Qhosts.

Qhosts modifies DHCP-issued DNS server settings in the registry, and 
creates a new HOSTS file and tweaks the registry to use that HOSTS file. 
It doesn't touch the original HOSTS file.

This post exhibits no Qhosts behavior, and Qhosts doesn't exhibit any
of this behavior. I think Daniel got it right - quit going to porn
sites. Better yet, quit going to porn sites advertised in Spam.

Also, to respond to another comment, the MS03-040 patch might *not* 
address this type of attack on a system. Internet Explorer fully patched 
with default settings *still* allows silent delivery and install of 
executables. POC was sent to this list weeks ago.
