What is a VIRUS?
• A Virus is a code written with the express intention of replicating itself. A virus attempts to spread from computer to computer by attaching itself to a host program. It may damage hardware, software, or data.
An example of a computer virus
• The RINBOT Virus affects all systems that operate on Microsoft Windows, including Windows 95, 98, 2000, NT, & XP.
• Adware is any software package which automatically plays, displays, or downloads advertisements to a computer after the software is installed on it or while the application is being used. Some types of adware are also spyware and can be classified as privacy-invasive software.
