When it comes to movies/shows, I generally just trust the listing; there's no real risk, particularly as I'm not a quality whore.

For games/programs, I'll mostly just check the download page to ensure it's from a verified, trustworthy group.

Mostly though, I've never felt the need to be as paranoid as some people suggest one must be when torrenting; despite doing this for 20+ years, I've not had any incidents since I was about 12 years old.
