[TowerTalk] Top Hat Calculator

[John Kemker]

Folks, you might want to be careful before visiting this website.  It 
has a virus/worm called "HTML:Iframe-Inf" which is an exploit to launch 
invisible frames and distribute malware.  I confirmed this by using a 
text-based utility called "wget" on a Linux machine, then opened the 
file retrieved (index.html) with a text editor.  At the bottom is a line 
that launches the invisible frame, pointing to a website called 
"michaelsbestway2findalawyer.cn", which is the malware site.

I have reports that some people's anti-virus doesn't report anything 
bad.  That's why I went to a different machine (a Linux computer) and 
downloaded the web page in a safe manner.  Visit the website at your own 
risk.
