I think this has been happening since about the time I reformatted because of virus. At the same time I put on a new McAfee anti virus/firewall etc! I'm on Broadband and my email programme is Incredimail but it also happens with Outlook Express. I receive incoming attachments ok! It's definitely not virus, I've scanned several times. As I only reformatted about a month ago, I didn't think it worth while doing scandisc, what do you think? The bands of colour run horizontaly accross the image. I run Windows XP on a 2ghz with 1g ram!
