I received an e-mail from a friend with an attachment that had a .EML suffix. Is this likely to be a virus? If not, what software should I use to open the file?
It is no more likely to be a virus than any other attachment you may receive. File extensions do not reliably indicate the content.
Normally, a file with EML as the extension is related to Outlook Express stationery or simply saved messages created in Outlook Express.
I'd use a text editor to open it, if I was curious. You may want to ask your friend first of all why he sent it to you.
