What Do You Guys Think Of The Program FairUse Wizard?

I have had NO luck with Handbrake and I have given up on it, its really stupid and when my DVD was done converting it came out blocky, and the sound was messed up. I want to try the program FairUse Wizard, but Im worried I will get viruses. Is it a good program? Do the DVDs turn out in high quality? Is it easy to use? Will I get viruses form it? Additional Info?
