Risk of getting caught is very low. Risk of viruses somewhat higher if you do not know what you are doing.
Risk is high, but not for what you think.

Because you are ignorant, your computer will get totally wrecked by using Limewire or bittorrent. Invaders will just dump viruses and spyware of every type onto your computer. First, they will hunt through your system to find passwords; then hunt for credit card numbers and your social security number. Having failed that, they will target your computer for a slow death.

So stealing music and movies won't be worth it.

Good luck and Happy Computing!
