VBS.Plan is a Visual BASIC Script worm that is detected by Norton AntiVirus (NAV) as VBS.LoveLetter.Variant with virus definitions prior to Aug. 28, 2000. This worm shares many of the properties of the VBS.LoveLetter worm. It spreads using MS Outlook and overwrites files with a copy of itself.
Additional precautions that you can take:
Some threats, such as this one, use the VBScript computer language to run. You can protect yourself from threats that use this language by enabling Script Blocking (Norton AntiVirus 2001/2002) or by disabling or uninstalling the Windows Scripting Host. Because the Windows Scripting Host is an optional part of Windows, it can be safely removed from your computer. (Some programs, however, need Windows Scripting Host in order to function properly.)
- If you are using Norton AntiVirus 2002, which includes Script Blocking, make sure that Script Blocking is enabled (the default).
- If you are using Norton AntiVirus 2001, a free program update that includes Script Blocking is available. Please run LiveUpdate to obtain this.
- For other versions of Norton AntiVirus, SARC offers a tool to disable the Windows Scripting Host.
- To disable the Windows Scripting Host in Microsoft Outlook Express only, see the Microsoft Knowledge Base document OLEXP: How to Disable Active Scripting in Outlook Express, Article ID: Q192846.
