In actual fact, Idea grew to become probably the most widespread laptop virus of any form – largely as a result of customers had been more likely to alternate Phrase paperwork with their colleagues than floppy disks or .EXE information.
1000’s of different macro viruses got here in Idea’s wake, fuelled by the truth that every macro was written in a excessive degree language and got here full with its personal easy-to-edit supply code – that means that any ne’er-do-well may simply create their very own variant with delicate adjustments.
One of many methods wherein Microsoft finally tried to curb the unfold of macro malware was to show a yellow warning strip alongside the highest of Phrase paperwork that contained macros.

And there’s no extra yellow strip. It’s modified its hue to crimson.
SECURITY RISK: Microsoft has blocked macros from working as a result of the supply of this file is untrusted. <Be taught extra>
And clicking on “Be taught extra” will take you to a Microsoft webpage the place it explains intimately why the macros have been blocked from working, and makes any person who actually nonetheless needs to run the macro to leap by way of some hoops.
No-one is suggesting that that is the top of macro malware, and even the top of makes an attempt by cybercriminals to socially engineer potential victims into permitting macros to run, however it’ll certainly assist cut back the possibilities of success.
What an idea, eh?
