===The Brain Virus (1986)===
----
Generally regarded as the first widely distributed virus affecting [[IBM]] PC–compatible systems. It originated in Lahore, Pakistan, and is attributed to the brothers Basit and Amjad Farooq Alvi, who operated a smallscale family-owned computer services business at the time. The virus functioned as a boot sector infection, spreading primarily through 5.25-inch floppy disks. When an infected disk was used to start a computer, the virus would load into memory prior to the operating system, allowing it to replicate onto additional disks. Of particular note is the inexplicable inclusion, within the virus code itself, of the creators’ names, business address, and telephone number. The creators reportedly framed the virus as a response to software piracy, though the effectiveness and intent of this approach remains a topic of much debate. The emergence of the Brain virus is frequently cited as a key moment in the development of the computer security industry, as it demonstrated, in a practical and deeply alarming manner, that software could self-propagate across distributed systems without centralized control. This terrifying realization produced a new category of technical and commercial response, and directly triggered development of the first anti-virus program by amateur coder and [[MindRape]] associate, [[John-david-mcafee|John McAfee]].
