Just worked it out - solved it through the options section of Outlook Express.
Just got my computer back from the shop after having it reformatted.
Now when I receive email attachments, I get a message at the top of the Outlook Express window saying "OE removed access to the following unsafe attachments in your mail:......". Is this Norton Antivirus 2004 or something to do with Outlook Express?
I have had this happen in the past and was told how to stop it but I have now forgotten!! Can someone let me know how to solve this?
