A Brief History of Computer Viruses, Bugs, & Worms

Kimberly L. Bolanos

The First "Computer Bug“

In 1947 Rear Admiral Grace Murray Hopper discovers a moth trapped between relays in a Navy computer. She calls it a "bug," a term used since the late 19th century to refer to problems with electrical devices.

NEWS FLASH . . .BUG CRASHES COMPUTER!!!!

Differences between a virus and a worm

Viruses

Need a host file.

Make their presence known by presenting text, video, and audio messages.

Typically take up computer memory used by legitimate programs, causing erratic behavior leading to system crashes.

Worms

Program that replicate itself from system to system without the use of a host file.

They generally exist inside of other files, often Word or Excel documents.

Worm releases a document that already has the "worm" macro inside the document.
