I'm sending e-mail with viruses in...

...to addresses I don't know. Every so often I will get an e-mail saying something like 'your message was not delivered because it contained virus x' and I don't know the address it was sent to. I have Norton Antivirus and it picks nothing up (I only ever check my e-mails on one machine). What is going on?

Someone is proabably spamming/sending viruses via email and spoofing it using your email address, so you get the replies. You are probably virus-free.

It's the oldest trick in the book when it comes to trying to kill peoples' email accounts. Does anyone dislike you?
