requires that all file-type information that is provided by Web servers is consistent. For example, if the MIME type of a file is “text/plain” but the MIME sniff indicates that the file is really an executable file, Internet Explorer renames the file by saving the file in the Internet Explorer cache and changes its extension. (In a MIME sniff, Internet Explorer examines, or sniffs, a file to recognize the bit signatures of certain types of files.)
W  e also discussed the Attachment Execution Service (AES) in the context of email attachments and files transferred via instant messaging applications. Internet Explorer uses AES to check downloaded files for safety, and to display dialogs to the user when permission is needed. The AES dialogs give the user more information and guidance than were available in previous versions of Windows and Internet Explorer. In addition to showing the source, type and size of a downloaded file, AES shows the user the publisher of executable software being installed, and issues a strong warning about software from an unknown source.
In an attempt to grab the user's attention for advertising, many Web sites display ads in pop-up or pop-under browser Windows. Several third-party pop-up blockers have been offered to help lessen this annoyance for users, but some of these pop-up blockers have caused problems of their own. The new Pop-up Manager in Internet Explorer blocks most unwanted pop-up windows from appearing. Pop-up windows that are launched when the end user clicks a link will not be blocked. End users and IT administrators can let specific domains launch programmatic pop-up windows.
The new version of Internet Explorer has another dozen security improvements, most of which do not affect users in normal circumstances. A few of these are better security for ActiveX controls and other scriptable objects, fewer possibilities for buffer overruns, better protection against windows placed on top of other windows, and better protection against windows placed off-screen.
