There's a PC out there somewhere in the internet (well I know in Australia at least), that's infected with a virus. It's sending masses of emails to us and no doubtedly to many others.

In the spirit of trying to help, how could I let the user know they are infected? It's a dynamic IP, but starts at least once a day from the same ISP. e.g. I now know it's current IP address.

I tried to net send, but that seems to not work. I thought it was NetBeui only anyway apparently it's TCP.

Any suggestions? Normally I'd let it slide, but this is beyond a joke now - it's been going on for a month and just recently it seems to have acquired the I-Worm.Bagle.au as well.

All I want to do is get a message to them that they are infected. Although that would look like a scam to me, this person obviously has no clue and would probably do what I tell them.
