Norton issue with installer

"I have downloaded the "MasterchestWalletAlpha_Bin.zip" once yesterday, and 3 times today, from the "Windows Wallet" link at http://www.mastercoinwallets.org/. The files extract just fine using either 7-zip or WinZip. But when I try to run the "Masterchest_Wallet.exe" program, my Norton deletes it, and gives me a message that the file contained the "SONAR.Heuristic.120" trojan.

I am still successfully using the "MasterchestWalletAlpha_Bin.zip" that I downloaded mid-March. But I wanted to update it."
