Multiple e-mails (scrambled)

A few days ago you helped me with some settings on forwarding 3-mails with pictures in them. I was to go to Tools/Options/Send and make sure HTML was checked. I did that and thought the problem was solved. It isn't. But to add to that--when trying to send an e-mail with a picture my virus scan comes up to check it out and will break it down into multiple e-mails and scramble the contents. For instance if I have 3 pictures in one e-mail and try forwarding it, my virus scan comes up and sayssending 1 of 3, 2 of 3 and 3 of 3. Of course when they are received they get 3 emails and all are mime (scrambled). Any ideas?? I'm at a loss...
