Occasionally I receive e-mails with attachments that Windows Live Mail detects as Prohibited File Types. Since most of them are from friends and relatives, I figure that most of them are probably safe to open. Still, I figure it's better to continue to be cautious by not opening these attachments. I would appreciate hearing from anyone who has an opinion one way or the other regarding the level of risk associated with disabling the Prohibited File Type detection. Thank you.
