Well, of course not. It's a computer.
But, if you want to make it more secure, I present you with the coolest site to test for leaks in those nasty, naughty little ports in your interconnected little 'puter body.
SHIELDS UP, TROOPS!!!!
Pass these tests to gain a little more sleep at night.
If you do not pass these tests, then you need to spend a moment to get some internet jimmies slipped on. Your 'puter's safety is at stake!!!!!!!!!!!!!
