Your Antivirus says..
Your antivirus software might report xpy as Spyware or a Trojan. xpy is written and compiled using NSIS, false positives are unfortunately quite common among NSIS compiled programs. The NSIS development team is aware of this situation and constantly works with software companies to solve such issues.
For more details on this issue, please refer to the NSIS forums.
If you have stumbled across this problem, please update your virus signatures first. If the problem persists, you can help by reporting a false positive to the manufacturer of your antivirus software.
