When this happened again, just a bit ago, I opened Etherial and it found no packets on the capture, so that would suggest that there is no hacking involved. I still wonder what is going on, because it seems to only happen while on the internet. It could be something to do with Opera, or something else involved in the connection, but it happens only on a random basis, and I have no idea of how to track it down.
