I really wish there was some more verbosity around these errors. JS:ScriptPE-inf [Trj] apparently is a generic label to any apparently malicious javascript. Except before I removed the forums, I looked, and there wasn't any there. Anyway, at the very least, there is absolutely NO javascript there now as I replaced the forums with a single static page, and have sent an e-mail to the one nmb mentioned. Hopefully I'll get some more info.
Asyn, I looked at those topics before writing this, again, no help. The JS just isn't there, and apparently this is now a blacklist issue not an active detection issue.
