Automatic Messages being sent unkowingly / Bounce Back Email Error
I have a co worker who is having an odd problem. From what I can tell automatic emails are being sent out but I can't fathom from where. She is receiving bounce back error emails.
Does anyone have any experience with this?
Thank you,

My best guess is that this is backscatter from messages sent by spammers to arbitrary (and non-existing) recipients using your corporate email address as From: address.

There isn't much you can do about it other than filter those messages and have them automatically deleted. The good news is, this will stop after some time.

I've run every antivirus I could think of,
msconfig > turn off everything not needed.
Searched through task manager and found nothing suspicious running.
As well as ensured no ad-ons or extensions were enabled on her browser.
It's a Windows 7, has all the latest updates ect as well.
If you need anymore information please let me know.
