Regular computer users often lack knowledge of malware and the methods employed by cyber criminals to infect computers connected to the Internet. Cyber criminals trick PC users into installing rogue programs by hiding file extensions and using deceptive icons. By default, Windows 8 does not show file extensions, and consequently, developers of rogue programs commonly exploit this setting. For example, you could potentially download a '.exe', file which has the icon of an MS Word file and named 'something.doc'. Since Windows 8 does not display the file type at the end of the name, you may be tricked into opening such a file without realizing that this could be malware. This tutorial describes how to change the Windows 8 settings to view file name extensions, and thus avoiding this problem.
1. Open 'File Explorer'.
Go to the Start Menu and type 'file explorer'.
Click on File Explorer.
2. Changing the settings.

New settings will be applied immediately.
