I discovered that an Ad. mail had been sent without my knowlwdge from my computer to all of my "Hotmail" contacts which I had built up over twelve years of computing. I discovered this when I found a substantial number in my 'inbox' as delivery failures. I do not have wi-fi or wireless and there is no other with access to my computer. The question is: How was this possible as it is most embarrassing to say the least of it. All of the mails are links to a website or websites that promote "earning money from home." I have my suspicion on a discussion forum that I registered for just prior to these mails going out?and could it be possible that I linked up my 'contacts' without being aware of it? And what do I do now?
