There is ONE option that you should deactivate in the Windows Control Panel as it is often used by viruses and trojans to fake dangerous file extensions. Once logged into Windows, open the Control Panel by clicking
Start -> Control Panel. Select the
Appearance and Themes entry and locate the
Folder Options applet.

Double click the icon to open the applet and
uncheck the
Hide extensions for known file types. If you leave this option checked, Windows hides known extensions such as .EXE and would display an application called MyApp.exe as MyApp. Numerous malware exploit this issue to hide the real extension. For example, an application Hello.txt.exe shows as Hello.txt which refers to a text file, but the real type is an application !
