Such as we know windows only recognizing some file type fruits executable newly, that is the file exe, com, scr, and pif. How if we will make extension file executable newly, for example extension ext( for example his file name : Anti. ext and nature of his file be like file Anti.exe). Usefulness of this technique is so that black out the program to file exe, scr, and com can be overcome. So that if file exe be like msconfig.exe blacked out because extension exe, hence we fixed can run the program msconfig the by changing extension, for example becoming msconfig.ext

To make the matter be like this easy very, we are only require to enter key newly into registry, for example extension ext which be like file exe, hence file reg yg enterred is :


Windows Registry Editor Version 5.00
[ HKEY_CLASSES_ROOT\.EVA]
@=" exefile"

Become his format is :
Windows Registry Editor Version 5.00
[ HKEY_CLASSES_ROOT\.EKSTENSIBARU]
@=" exefile" to be like file exe
@=" scrfile" to be like file scr

Is while to be like file com, hence have to be entered also in file regi key PersistentHandler This technique can is also used by virus to system his defence in computer, that is with :

. 1. Change handling of file dangerous, for example binding file jpg exefile, whereas virus file fixed fasten ( join forces) file jpg in fact, without changing extension file, is while substitution extension for file draw jpg is extension will different, for example tmp

. 2. Incognito to become the file which similar with file undangerous so that difficult detected for example virus for file extension d11 at first sight look like with dll ekstensi etc.

Note :

To alter, for example file scr before all use the program wafting icon alone, we wish the file scr use the icon from outside, for example property windows without compiling again file scr, hence we require to changing value registry, at key :

[ HKEY_CLASSES_ROOT\SCRFILE]
that is in :
Value DefaultIcon from % 1 becoming, for example :: % Systemroot%\System32\Shell32.Dll,-154
