Lindsay, I didn't open the attachments. I'm using Eudora 5. I have the Microsoft Viewing Pane switched off. I have my view in Windows Explorer set to show full paths, so I could see that these viruses were .doc.pif and .mp3.pif.

This is what happened: as I was downloading my mail - before I even saw the virus mails - Norton AntiVirus came up with a notice saying a virus was present. I immediately quarantined it. When the mail was downloaded I went searching through the filtered mailboxes and found the two mails in one. I clicked on them to open them - *not to open the attachments*, mind, just to open the mails.

After that, every few days I'd get another notice from Norton saying a file was trying to run malicious code.

It's a mystery to me how these files executed. The emails themselves were blank - the address was cube@zigzag.pl, but there was nothing in the mails themselves, just the attachment icons, which I left strictly alone. And I didn't go into them in Explorer, either, simply let Norton quarantine them immediately.
