The gutter slime have a few more sites.  From Sunbelt spyware researcher Patrick Jordan:

securitycaution(dot)com
dnserror404(dot)com
todaywarnings(dot)com
updatesystempage(dot)com 
yoursecuritysystem(dot)com 

Installs of SpyAxe, etc. are a plague right now on the net.  Mark Russinovich of Sysinternals,  (you’ll recall him as the man who broke the Sony rootkit story) writes about these rogue programs here.

Update:  And the venerable Andrew Clover drops by the blog to give us a few more:

needupdate(dot)com
warningmessage(dot)com
notfound404(dot)com
