Description
Unsafe hyperlinks are links that might pose a security risk if users click them. Clicking an unsafe link could compromise the security of sensitive information or harm the computer. Links that 2007 Office considers unsafe include links to executable files, TIFF files, and Microsoft Document Imaging (MDI) files. Other unsafe links are those that use protocols considered to be unsafe, including msn, nntp, mms, outlook, and stssync. By default, 2007 Office applications notify users about unsafe hyperlinks and disable them until users enable them.
