can i test how secure my networks and pc's are?

Hi all,

I was wondering if there were a software or website where i can run some sort of security test to test how secure my network and pc's are from possible internet attacks?

Thanks lads, It would seem i am very secure, nothing can get through at all, I am aware though that my network and pcs can never be fully secure especially whilst using Windows and partly Wifi.
