I am having problems opening a .pdf attachment sent by my bank that
confirms my email account so I can use online banking. The file does not appear to be corrupted since I forwarded it back to the bank and it worked. I suspect that there are some security measures in the file that might be preventing gmail from allowing me to download it. Here are the email instructions from the bank:

[Begin ---
Step 1: Verification Process
To verify that you are able to open the attached TEST e-Statement,
please click on the attached PDF file. Remember, you will need Acrobat
Reader� 5.0 or greater to open the e-Statements attachment. [Note: I
have Reader v8]

Step 2: Enter Password
You will then be prompted to enter a password. The password is
"[XXXXXXX]" . Once you have entered the password, an example of a
monthly e-Statement will be displayed.

Step 3: Response Request
Once you have successfully opened and closed the test e-Statement,
please click REPLY and then click SEND. Upon receipt of this
response, you will be enrolled in the e-Statements product. Please
note, we cannot begin electronic delivery of your statement until you
respond to this e-mail.
--- End]

There is a note on the email next to the attachment that reads: "104K
Gmail could not scan this file for viruses."

When I try to save the attachment, I get an error message that reads
"Internet Explorer could not download attachment from
mail.google.com. Server connection reset."

Help is much appreciated!
