Agree, better to be protected than not at all. Of course you're not going to stop the determined hacker, after all if they can hack NASA they can hack your desktop PC but you will stop the casual hackers who are often the little toejams that spread trojan's and other viruses. People break into high security banks but you still close your front door at night, it won't stop the determined intruder but will stop the casual thief walking away with yout TV and VCR.
