Immunization from VBS Viruses
System infections like the VBS.LoveLetter worm and the new VBS.NewLove worm are effective primarily because of the type of scripting language in which they are written - Visual Basic. Windows does enable users to disable the ability for their system to run Visual Basic Scripts (VBS) by disabling the Windows Script Hosting (WSH) functionality. To disable WSH and prevent VBS viruses from infecting your machine:
Windows 95
Windows 98
Windows NT
Windows 2000
Windows 98
Note: Windows 98 includes WSH if a standard installation is chosen, if Internet Explorer 5.0 is installed, or if you downloaded WSH from Microsoft.
- Go to the [Start] menu, point at [Settings], and then [Control Panel].
- Double-click [Add/Remove Programs].
- Select the [Windows Setup] tab.

- In the Accessories window, scroll until you find the entry 'Windows Scripting Host,' then click on the checkbox next to it to deselect it.
- Click [OK] in the Accessories window.
