- F-MACRO - Scanner and disinfector for MS Word document macro viruses
- Copyright (c) 1996 Data Fellows Ltd
-
-
- OVERVIEW
-
- F-MACRO is a DOS program which searches Word 6.x and 7.x documents and
- Excel 6.x and 7.x documents for known Word and Excel macro viruses.
- F-MACRO is able to disinfect them by disabling and overwriting the
- viral macros. F-MACRO is able to parse the complex OLE2 file structure
- of document files making it very fast and accurate.
-
-
- TECHNOLOGY
-
- This scanning and disinfection technology was developed by Data
- Fellows Ltd for the commercial F-PROT Professional package. F-PROT
- Professional for Windows, Windows 95, Windows NT and OS/2 as well as
- the realtime Windows VxD scanners have these macro scanning features
- built in to their normal scanners.
-
- If you are running a VxD-based background protection from the F-PROT
- Professional suite, you will be notified on infected document files as
- soon as you try to open or copy them or when you are receiving such a
- document as an e-mail attachment or downloading it from www.
- Disinfection can also be done in realtime. A VxD-based solution
- provides significantly better protection than antivirus systems
- relying on the Word or Excel macro language.
-
- For more information on the F-PROT Professional suite, see the web
- site of Data Fellows at http://www.datafellows.com/ or the web site of
- the US publisher, Command Software Systems at
- http://www.commandcom.com/.
-
-
- USAGE
-
- Give scan path or drive as the first parameter.
-
- Options:
-
- /DISINF disinfects infected document
- /AUTO automatic disinfection, no prompting
- /ALL scans files with any extension
- /REPORT= Send the output to a file
- /APPEND Used with /REPORT - append to existing report
- /NOSUB do not recurse sub-directories
- /LIST list all scanned filenames
- /COMPRESS removes unreferenced data from file
- /BACKUP makes a copy of the file before disinfecting it
-
- Examples:
-
- F-MACRO C:
- F-MACRO C:\DOCS /ALL /DISINF /AUTO
- F-MACRO Z:\USER\INFECTED.DOC /DISINF
-
- F-MACRO returns following errorlevels:
-
- 0: No viruses found
- 1: Error during execution
- 3: Virus(es) found
-
- Notes:
-
- We recommend you make a backup copy of important document files before
- disinfecting them, just to be safe.
-
- In order to be able to scan all document files, Word and Excel should
- be closed down before running F-MACRO: otherwise it will keep
- NORMAL.DOT and possibly other files locked. F-MACRO will give a
- warning message on such files.
-
- If you have document files with non-standard extensions (something
- else than DOC or DOT), use the /ALL parameter to check all files.
-
- If an another virus scanner still thinks that a document file is
- infected after being cleaned by F-MACRO, use the /COMPRESS option to
- remove unused slack areas from a DOC file. You can also use this
- option if a document has already been disinfected manually via
- Tools/Macro but you receiving a false positive from some scanner.
- /COMPRESS will compress all scanned files which have been 'Fast-saved'
- by Word or Excel. If you still get alarms from a cleaned file, open it
- again and re-save with File/Save As.
-
- Infected DOC files are always templates in structure, regardless of the
- file extension (normal extension for templates is DOT). Only templates
- can contain macros. A side-effect of this is that infected files can
- usually be saved by Word only as templates and only to the default
- template directory.
-
- When disinfecting infected files, F-MACRO will normally change the file
- back to a normal document. However, some files have originally been
- templates so F-MACRO tries to determine this and preserve them as
- templates after disinfection.
-
- If the file contains extra macros after disinfection, it has probably
- been a template in the first place and will not be changed to a
- document by F-MACRO. The same will happen if:
-
- - The document contains user-defined menus or toolbars
- - The filename extension of the file was DOT
- - The filename of the file was NORMAL
