The MacMag virus, also known by various other names, was a computer virus introduced in 1988 by Richard Brandow, who at the time was editor and publisher of MacMag computer magazine in Montréal.
Operation of the virus
The virus infected Macintosh computers, and the intention was that on 2 March 1988 all infected computers would show the message "RICHARD BRANDOW, publisher of MacMag, and its entire staff would like to take this opportunity to convey their UNIVERSAL MESSAGE OF PEACE to all Macintosh users around the world", and the virus would then delete itself. According to the virus itself, it was written by Drew Davidson. The virus was a boot sector virus, which was spread in the form of a HyperCard stack called "New Apple Products," which contained very poor pictures of the then-new Apple scanner. It copied a resource into the System folder on a Mac, as an "initial" program, which would run automatically every time the system started up. The program then copied itself onto any bootable disk which was opened.
Brandow intended the virus to be benign, giving a friendly message and causing no harm. However a bug in the virus caused infected Mac II computers to undergo system crashes before this date. Another bug, which affected very few users, caused files other than the original virus to be deleted during the termination stage. It also caused a great deal of anxiety among users who found that their computers were infected with an unwanted program the nature of which was unknown. The virus infected Aldus software's FreeHand, and Aldus had to recall thousands of copies of FreeHand, leading them to threaten legal action.
