I thought I had more examples saved, but don't. What do I do with this kind of stuff?

And we don't have a virus, and I've been running SBS&D checks every few days.

NetskyB piggy backs using an email address from someones address book if that helps, so someone could be getting one from what seems like your address, and so it gets sent back to, where in reality, it's from a totally different email account.

So it's ok to ignore these or what?

Yeh, should be, I've been getting loads of them in my junkmail box recently, Netsky.B is all over the place at the minute, I've just been deleting them and no harm done.
