Do Not Hide File Extensions of Known File Types
All Windows operating systems, by default, hide the known file
extensions in Windows Explorer. This feature can be used by virus writers
and hackers to disguise malicious programs as some other file formats,
such as text, video or audio files. For example, a malicious program file
named "readme.txt.exe" is displayed as "readme.txt" in
Windows Explorer (see illustration below). Therefore users are often tricked into
clicking the "text" file and then into inadvertently running the
malicious file.
To avoid this confusion, you are recommended to change the Windows
Explorer setting to "Not hide the
File Extension of known File Types." This can be achieved by clicking
on one of the following files, and saving it to your local hard drive,
then double-clicking on the file to run:
Windows 95, 98 and NT 4 users:
Windows 2000 users:
Afterwards, files will be displayed with the complete file extension as
shown:
Important Notice: There are still some file extensions, which the Windows
operating system will always hide, such as
the shell scrap files with the extension .shs.
