About Viruses

A malicious program which integrates into and affects a program or file on a computer system, without the knowledge or consent of the user.

Viruses were once the most common type of malicious program and there are literally hundreds of thousands of viruses in the wild. These viruses are designed to attack various targets on the computer, including:

  • Executable or data files, such as applications, games and documents ( file virus)
  • the boot sector ( boot virus)
  • Macros ( macro virus)

And much more.

A virus almost always arrives on a computer system as an executable file, most popularly as an e-mail attachment. Some viruses are spread as part of a Trojan's payload. Other common ways viruses are spread are through removable media such as floppy disks, CDs or USB thumb drives.
