Norton Email Error Pop-ups Won't Stop
So I've been encountering a problem since I started my laptop today. I keep on getting Email Error pop-ups from Norton, saying that 'my email message' was unable to be sent. But here's the problem- I didn't send an email message.
It appears to me that spam bot emails are sending out hundreds of emails (to people I do not know and are not on my contact list). But my email is not being used, the spam bot emails themselves are doing this. What I want to know is why is my IP address being used to do this (if this is even the problem?)
I did not get only one email error, but around 4 different email errors. Here are the image links:

As you can see in the screenshots, it says 'Your email message,' but the problem is that I'm not sending these email messages... What could the problem be?
These were the 3 different errors I encountered. I blurred out the emails that were having the spam sent to. All of the emails were yahoo emails.
Also, the sender (which in these pictures is seen as email@example.com) was not the only one. I also remember firstname.lastname@example.org being a sender in one of these emails, as well as several others.
Note: I do not own any of these emails.
I just want to know why I am being notified of emails I am not sending... I assumed it was because the senders were using my IP address, and if so, I want to know how I can solve this problem.
I am also running MalwareBytes Anti-Malware, and so far I've encountered 2 objects that have been detected to be harmful. I will give you an update on this when the scan is complete.
I also have Norton Security Suite, but have not started a full-system virus scan yet.
I don't know if it helps, but I haven't been to any harmful websites lately that could have contributed to the problem.
I have researched the issue for around 3 hours at Yahoo!, Google, etc., with no solution. Any help is REALLY appreciated.
