It seems that every e-mail I send has an attachment included, needless to say it is not suppose to there!!!!

It doesn't seem to have been picked up by my virus checker or the Hotmail virus checker so I have done a Norton full system scan which has found a few tracking cookies and a Trojan which it cleared, but it still seems to be happening.
Hmm, sometimes anti-virus programs put what looks like an attachment on sent emails, but it is usually only a small script saying something like "This email has been checked and is virus free" or words to that effect.
On the other hand, your PC may have been hijacked or hacked in order to spread nasties. Have you tried sending an email to yourself, to see if there is any mention of an Attachment - without opening the attachment, if any, of course.
Tried sending an e-mail to myself but nothing, also all incoming e-mail don't show any attachments. So I sent one to my Hotmail and lo and behold there it was. It passed the Hotmail virus scan and that's how I got the info on it. It opens in Office Photo Manager as a small white square.
