Is there really a virus that can do this?

A friend got a virus that caused her to start receiving emails from MY email account as well as from a few of her other friends’ accounts. Many of these were emails that were sent to other people and never had her email attached to them in any way.

I ran a virus check and I was clean, but even if the virus was on my computer, why would my emails go only to her?

She says the virus was hers and that she received about 300 emails from me and a couple of her other friends. I can’t understand how this would happen, though. How would a virus on her computer give her access to my email? Why would she not receive emails from everyone she knows instead of just a few?

I have not seen any of the emails. I only know that she has read at least one of mine because she told me. Is this scenario possible or am I just being naive?
