Was it RC1 or 2 then? As I'm not seeing it with RC3?
The way AV programs work, or one way at least, is they look for "signatures" of known viruses. Each virus tends to have a group of bytes that distinguishes it from other programs - in the same way, if you wanted, you could probably go through a library and pick say the first sentence out of each book. You could then bring in a new book without a cover, compare the first sentence against your list of known sentences, and decide whether it matched anything you'd seen before.
Occasionally you might get two books that have the same first sentence, and so one might be misidentified as the other. It basically works exactly the same way with viruses. Because it is just a string of characters, they could appear in other programs, and occasionally do, that is how false positives occur.
So, when we built rc2 (or 1?) it just happened that the exact sequence of characters appeared in our setup file as must appear in some virus. It's something that Symantec have to update in their database, and once I know which build I can let them know - they have a set process for letting them know about false positives. They'll then double check our file, confirm with what else they know about that virus that it definitely is a false positive and then update their definition list, and that will go out the next time they send out an update (usually in a day or so).
For now, RC3 seems ok so you should be able to download and run that if needed.
