I also use Trend. I've seen occasional false positives, but not recently. I think it's Ad-Aware that's falsey reporting positives on some ancient mIRC installation files that I have hanging around. As I understand it, it's due to the compression scheme Khaled used to use, but no longer does. I suggest you resolve the issue by reporting it to Trend and asking them to respond with the results of their checking. I'm sure we'd all be interested in what they have to say. I also use other AV and anti-trojan and anti-scumware programs on a regular basis. Only Ad-Aware regularly reports mIRC installer as a trojan, and they haven't responded to my reports.
