SYMPTOMS
When you open a PowerPoint 95 or PowerPoint 97 presentation directly
from a Web page, Microsoft Internet Explorer does not display a
security warning. In contrast, when you attempt to open other types of
files, such as program (.exe) or archive (.zip) files, Internet
Explorer displays a message warning that these files might potentially
damage your computer.
CAUSEThe versions of Internet Explorer listed at the beginning of this article do not recognize that they need to display a security warning for PowerPoint (.ppt) files. RESOLUTIONTo resolve this problem, download and install the PPTWarn.exe file from the following Microsoft web site: http://www.microsoft.com/ie/security/powerpoint.htmAfter you install this update, Internet Explorer will display the following security warning when you open a PowerPoint presentation from a Web page: NOTE: This program does not disable interactive and action settings, it just warns you of the potential risk. STATUSA top priority is to provide a complete PowerPoint solution, which Microsoft will make available to customers as soon as possible. MORE INFORMATION
PowerPoint presentations can contain text or graphics that run
programs that are already installed on your hard drive. For example, a
slide can contain an icon to run Microsoft Notepad or Microsoft Excel
when you click on it. In addition, PowerPoint 97 supports mouse over
events; you can trigger an object's action setting by dragging your
mouse across it. For example, you can insert a picture that runs
Calculator when you drag your mouse across it.
PowerPoint 7.0 and 97 let you assign interactive or action settings to graphics or text. These interactive settings make it possible to create rich multimedia presentations in PowerPoint. For example, if you create a presentation about your new software, you can create an action button to start the program during your presentation. The PowerPoint 7.0 Interactive Settings feature can only be used to run programs that are installed on your computer, or to run multimedia files or open Web pages in your default browser. You cannot run any program that is not already installed on your computer. While it is possible to have an interactive setting that starts a potentially destructive program (such as Format.com or Fdisk.com), those programs generally display their own warnings before they run. The PowerPoint 97 Action Settings feature can be used to run either a program on your hard drive, or macro code stored in the presentation. It is possible to write a PowerPoint macro that does something destructive. However, if a presentation contains macro code, PowerPoint displays the macro warning when you open the presentation. NOTE: There is nothing unique about presentations viewed from the Internet. If you receive a PowerPoint presentation on a floppy disk or open it from a network server on your company's network, it still may contain action settings or macros which could potentially be destructive.
