Deleting names in the forwarding function


New Email
I was reading my email the other day and went to forward it when I noticed after opening that there was an entry thay I did not create. I could not delete it. It has no email address and is not in my contacts list. My wife has her own address and has the same issue. It is in bold letters. I was concerned as to how it got there and how do I delete it. I have two other email address in Hotmail and they do not have this issue. I have ran every security scan I have and nothing shows up for either virus or malware. I would like to know if this is something that might require an expert to solve. Except for just being there it doesn't seem to do anything.
