I want to download a program kind of like ares/limewire .etc but i want one thats COMPLETELY SAFE because i just got a new and expensive computer and i dont want it harmed. I'm going on a roadtrip and i just want to download some movies to watch during the trip! or is there another/simplier/less risky way to be able to watch movies during the roadtrip (i cant get access to the internet on the road btw)

what i use is completely safe which is frostwire

I use vuse, and I haven't had any problems. You can stream or download videos.
