here is my best suggestion, keep anything you must have backed up on something else, memory card, cd, dvd, tape drive, dlt, external hard drive (something not connected when not in use), keep your av updated, use a password to access your router as there is now viruses/bugs that can get into the router if not passworded properly, if you have particulary sensitive information use a hardware firewall, sonicwall is good as well as many others, and cross your fingers, big brother can get in anyway (they make sure of it, so someone else probably could as well) dont do anything illegal and you should have nothing to worry about.
