W32.Xpaj.B

We are a small software developer using Delphi and we have recently been getting a warning from Norton Internet Security that some releases of our product are infected with the W32.Xpaj.B virus.  As far as we know we do not have an infection (we have tested with other anit-virus packages) but obviously some code signature in our product is triggering Norton Internet Security to report this problem. This has been happening for the past 10 days after having received a Live Update of virus signatures.  We need some help on this perhaps to remove whatever is foolingNorton into thinking we have this virus
