False positive?

NIS 2010 ran a full system scan today and quarantined a file  sub2divx.exe  as a virus Infostealer.

It is a small free program for adding subtitles to divx files and I have used it for a couple of years.

 

This is the first that Norton flagged it.

Therefore I suspect it is a false positive, but would like to be sure before restoring it.

 

Is there a way for Symantec to check it?

The program can be downloaded from this page and does not require installation.

 

Thank you, Alex.
