Just a little, pratically impossible. In fact in those circumstances the only way anyone is going to get into your computer is if they sit down in front of it which is probably where the items in event viewer came from.
If you are not on a network Norton Internet Security is a little superfluous don't you think.
If you are connected to the Internet with a modem plugged directly into your computer then you are on a network and you are more vulnerable than if you were on a Local Area Network working through a router.
See of you can find OneCC.inf see what is inside that.
