Question about NIS 2012 19.7.1.5

I've noticed since I purchased Pavtube Blu-ray Video Conversion Ultimate that every time I'm using it to covert a movie for streaming to my Xbox 360/hdtv (no Blu-ray player), that NIS always finds threats. How do I stop this, as store bought movies, obviously aren't a threat It happened with the Batman Begins Blu-ray and now with a 3 disk Blu-ray set titled Rambo, which includes First Blood, Rambo First Blood part 2 and Rambo 3.'
