I was trying to investigate and reply to this last night, but was having problems with the forum.
One of the sites I use to check these things reports your wordpress is out of date and currently there are a huge amount of sites having problems with vulnerabilities in out of date wordpress versions. One related to themes, timthumb I believe.
Since there have been a number of alerts by the web shield (image1), this has effectively passed on the the network shield which is blocking the site right now.
I believe the problem is your jquery.js script (image2) may be infected/hacked.

There was a similar post about this jquery.js file (try a forum search for the file name) and they replaced the jquery.js file and that resolved the problem, but id doesn't resolve the reason why, so you need to keep wordpress up to date.
