[amsat-bb] Virus or not in ARISSAT software

When I download the setup file at http://www.arissattlm.org/download/ARISSatTLM_050_Setup.exe my Norton complains that a WS.Reputation.1 virus is present and it deletes the file. Do I have an incorrect link or is this merely the heuristic detection in Norton falsely identifying a virus? The link to the file is on the AMSAT web page so my assumption is that the file is OK.

Thanks, James W5AOO
