Seems McAfee is at it again... (this happens every few years it seems)...
Looks like their latest virus definitions update has flagged Hurricane as a possible "trojan". This is obviously not true, and they have been notified of the issue. Not sure when they will have this resolved.
In the meantime you can download the uncompressed Hurricane executable and place it in your Hurricane directory, and McAfee shouldn't consider it a Trojan (because it doesn't extract in real-time). It is a slightly older version, but should work.
