Also realise that there could be many other options,
which may include:

1) other net users trying to hack into your computers,
or simply pinging it
2) certain background programs which are not obvious
(don't show up on ctrl-alt-del either)
3) your virus programs, window auto-update-check etc
checking for updates...
