Macro.Word.Mark
This is an encrypted Chinese Word macro virus. It contains five macros: A, B, AutoExec, AutoOpen, ToolsMacro (stealth). The virus replicates itself when documents are opened (AutoOpen).
Depending on the random counter the virus creates a new document and writes to there a text in Chinese. It also creates the C:\X.TXT file and writes to there “0″ or “1″ also depending on the random counter. On next Word loading (AutoExec), if there is “1″ in that file, the virus appends to the C:\AUTOEXEC.BAT file the commands that formats the hard drive:
format c:/u/V:MARK>nul
