Because at the top of the page a rogue script is trying to load: <script src=http://forums.weddingbells.ca/ubb_js/google.js>. This script is setting off my threat warning. It appears to try to load an exploit kit.
Today Windows 7 (as it is patch tuesday) had a shitload of security updates. My guess is someone is trying a zero day exploit. If you running Windows make sure you have installed all of the updates (especially if you are still on some version of XP).
You Mac people are getting more and more vulnerable everyday. Make sure you have updated your computer as required. Lets have the XPT hate without the computer viruses, except for Brendan, who can only get rid of the viruses on his computer. It is a Canadian url, so Brendan may be the cause of it all.
