Well considering it's been reported as a phishing site, the general opinion would be to, well, not go to it basically.
However this site is reported by all the various software vendors, Firefox and Google as a potential phishing site. So something's happened on the site at some point to cause this, intentionally or otherwise. The forums on the site in question are bemused.
These things work on a cascading basis - Google's decided it doesn't like it, it feeds the website stopbadware.org which is also used by Firefox and Chrome for their blacklists. Likewise other programs like Norton and co monitor the trends too and update their logs accordingly.
The issue may be temporary and will probably resolve itself in due course. Not the first time a Google automated system has screwed things up.
In the meantime for Firefox you can turn the warnings off by going to the Tools Menu -> Options -> Security and the "Block reported attack sites" option. Note that this will reduce protection for sites outside of the site in question.
