I'd also run 'hijack this' and 'cwshredder' as well. I went to the site and didn't see anything obviously 'dynamic' (flash, applet, etc) that would make it different than any other page. I did see a 'javascript error' message being suppressed (i have them set to be suppressed), but I see those on all kinds of sites.
btw, the message was:
error: Invalid Character
line: 2
char: 7
url:
www.hgtv.com
I looked at source code but the page references about 8 javascript library files and I'm not about to start parsing them. Try installing 'mozilla firefox' at --
www.mozilla.org and see what it does at that site.
