Since most of today's computers do not require a boot disk to start, these viruses are becoming less common, but they can travel on disks that contain other types of files. When you start a program containing a virus, the virus usually loads into your computer's memory. From then on, the virus can infect any other program that is executed.
Macro viruses are technically a variation of program viruses.
Once a template is infected, every single document or spreadsheet opened with the program is also corrupted. Because they infect common office applications and can spread between platforms, macro viruses have recently become widespread. This point may seem obvious, but most virus hoaxes scare people who don't understand this basic concept. Inc. All rights reserved. Privacy policy .
