What is your operating system and email client?
What happens when you try to open a PDF file attached to an email message?
Windows 7 and MSN.When I try to open it is says "running security scan" and then does nothing.

Sorry, I don't know how MSN works - is that a browser-based email client?
"Running security scan" sounds like some antivirus software doing that; what security software do you have installed?
