Microsoft Software Media
Microsoft distribution media shipped with Form virus.
In 1995, Microsoft acknowledged accidentally distributing software installation floppy disks (reportedly including some for Windows 95 upgrades) infected with the common 'Form' boot sector virus. The infection likely occurred during mass disk duplication. While not destructive, the virus caused audible clicking sounds on infected PCs on the 18th of the month.
