I'm getting complaints from a mate that I'm sending them emails with attachments that have got a virus in. Now I've not used the email account since January and I've set up the account so every email I send is copied to a sent folder and every reply is forwarded to my new email account. The las email I sent was 6/1/06
I've emailed a few people in my address book to see if they have had any problems and they havn't.
I've changed my password just in case it was hacked and it's still happening. I'm use Mac's so I don't have much knowledge of virus and trojan problems so if anybody has got any ideas what's happening I would love to know

What Virus Software You got running on your mac

Norton anti virus 10.1 and ClamXav 1.0.1.

have you ran a scan to see if there is a virus on the system...

You could be being "spoofed" (it appears to come from you but doesn't)
