Zone alarm show virus in dvdrebuilder

I ran my zone alarm virus protection today and it showed win32.auti.a virus in some of the dvd-rbv zip viles had not done this before and I cannot find out anything about win32.auti.a virus.

What ever this was it was not a virus in dvdrebuilder reinstalled zonealarm and re ran it and it did not show a virus. Did not think this could be true but this was the first time a virus programs said something was a virus when it was not. Going to zone alarm forum and ask them about it.
