I will add this. When I said that you should treat this as any other network, I was not joking. You should always watch for malicious files, regardless of how many people approve of them. You can and will be infected by files that you did not think could hurt you, only those programs will cause other problems than what you where asking about.
Long story short, please be careful as you can still get hurt by the most innocent looking things. Any software developer could tell you that, but please take this from someone whom fixes malware issues for free. I do what I do because I love it. And that means that I have seen a lot.
