hoax? nope. beyond that, all we can tell you is that a virus by that name does exist and hence the possibility that you may be infected by it needs to be checked out. mIRC that you download from mirc.com in and of itself is not infected. whats on an individual's machine, we have no way of knowing. whether or not a false positive is being triggered in trendmicro products, until they tell someone they have confirmed that, all we can tell you is what they have so far told others: they are investigating that possibility. keep checking the thread referred to for any updates. its easier for those following the subject to look at one thread instead of several scattered about. that thread has links to info about that trojan and what files and registry entries to look for.
