Went to view the forums and my AntiVirus reported a blocked trojan from a script on the main forum page. Clicked the General Discussion forum link and AV pinged a second blocked trojan alert, again from scripts. Blocked Battle.net scripts in my browser and I've stopped getting alerts about blocked trojans.

Unfortunately, my AV isn't giving detailed info on what trojan was blocked, only that it was a trojan and that the source was your site scripts. I'm running Firefox with AdBlock and NoScript, with Avast for AV.
