I have added level1Remove and Level2Remove in the security key for outlook 2007 in regedit.
But I still can't just open a pdf from the email, I get this dire warning and can only save it to disk.
The warning reads:
This file may contain a virus that can be harmful to your computer. You must save this file to disk before it can be opened. It is important to be VERY certain that this file is safe before you open it.
Type: Adobe Acrobat Document
This doesn't' happen with word or excel documents, only pdfs. Outlook 2007 on windows 7, and I'm running adobe reader 9.0.
