The problems you might encounter if you're sharing files over a peer-to-peer network include copyright infringement. Some of the files that you might be sharing, might not be yours to share. It's also very easy to pick up a virus, because you really don't know what you're downloading, and you really don't know who you're downloading it from. Also, you're opening a port or connection in your computer that somebody with the sophisticated knowledge can actually use to access your computer. It is like opening a second door, one door is connected to the internet and you're opening a second door allowing people to download things. This can be exploited and somebody can gain access to your computer.
