I'm using Avast! and I also get informed that a trojan was blocked when I visited the site. (I used to visit it regularly too.) I don't get anything from their forums though, so maybe ask someone there what's wrong or stick to checking that while everything's being sorted out?
Also, from what I remember, wordpress sometimes shows false positives so perhaps it's just another one of these.
Besides, if you're using No-Script or another script blocker, the infectious script should also get blocked.
