This is a subject I have spent considerable time on, as I am a school teacher and our classroom does not have Internet, which would keep me from sharing some of the great content that is online with the kids. First, as I said, stay away from anything mentioning torrents. A torrent program is two-way, you're downloading while uploading to others at the same time. Torrent programs are inherently risky because of the access level they need to your system to function. There is nothing inherently "insidious" about this, it's just the way they work.
What is the best method for downloading free movies safely?
