Concept/Laroux

Author: Chris Brook

1995/6

The mid ‘90s marked the dawn of macro viruses written into software like word processors and spreadsheet programs. WM.Concept, a 1995 virus was shipped with Microsoft Word for Mac CD ROMs. The virus was largely harmless and merely displayed a ‘1’ message box on infected PCs and Macs. Laroux, a similar virus later surfaced for Microsoft’s Excel, yet didn’t hit Macs until 1998 with the release of Excel 98. Like Concept, Laroux was nondestructive and simply appended a macro sheet called “laroux” to users’ workbooks.
