I am not suggesting that people whose A/V software is detecting trojans/viruses as being a part(either an .exe or a .dll) of DVDFab are using cracked versions of Fab, but I am saying that many cracks out there are actually trojans/viruses. I have always paid for the Fab and have never had any security issues with the Fab. Again, my intent is not to offend anybody who is having security issues with the Fab, but if I did, I apologize.
