It isn't unusual for genuine software to sometimes be flagged up as suspicious. I once installed the Demo of Borlands Delphi 4 (might of been v3 actually). McAfee instantly flagged it up as having a virus - simply because it had found the TServer demo program which demonstated how to use a TServer component for socket programming.
I had some very heated emails with borland about that, and eventually they took it further with McAfee. It's never happened again.
Even realplayer was showing up sometimes as being spyware. Admittedly it actually was, but it was harmless and it was known as being a very popular media player which was harmless. Still people grumbled about it being a major security risk (because it gathered annonymous statistics). Real player doesn't seem to be such a big hit these days since the AV companies and their counterpart spyware pals did their best to destroy reals reputation.
With regards to finding no info online, no news is good news. I'm sure if it was a dodgy program, it would of shown up all over the place on google as being of dodgy creation. Remember if it's bad, people are far better at shouting about it to alert others.
That doesn't mean it's nothing to worry about, it could be something new which hasn't been found yet (unlikely as most AV companies actively hunt for new threats). If it requires internet access, block it. Just in case.
If you still don't find anything worrying in a week or so, I personally woudn't worry about it too much (though I'd still keep it's iinternet access restricted personally).
Good luck
I need a new signature... i'm bored of the old one!
