Apparently, This Freeware Comes Up As A Trojan On Some Antivirals, If Not The Software Itself It May Be The Site Is Infected. (It can happen to legitimate websites that don't secure their site against viruses.)
I never had a problem with it, and it passed *my* antiviral, but (see below) some people say their antivirus found (Or believe it found) a Trojan embedded in it.
