A few days ago, I noticed that I have been getting return messages in my GMail account. I opened one of it, and noticed that I was actually sending out spams out to people in my contact list.
Thinking that it might be spoofed, I checked my outgoing folders, and to my surprised I found that I did sent out those emails. From my history of so many ancient years of using the computer, I have never got infected by a virus, or a malware before. I have yet to had any of my accounts hacked. Disbelieved, I surf around wanting for an answer.
