What is the difference between Viruses and Worms? 5

Viruses and worms

Viruses and Worms are malicious programs that can travel between computers as
attachments on email or independently over a network. These terms are sometimes
used interchangeably; however, essentially they are different. Worms spread from
computer to computer, but unlike viruses have the capability to travel without
any help or human action. A worm can replicate itself which means that it can
send copies of itself to everyone listed in the email address box on a system.
Viruses, on the other hand, need to be activated through a human action. Another
difference is that viruses modify existing programs on a computer unlike worms
which can install back doors or drop viruses on the system they visit. A few
years ago a worm called ‘Love Bug’ was triggered by a 23 years old student in
Philippine. Its code was written in VBScript, and it traveled on the internet as an
email attachment. It could send copies of itself upto 300 addresses found in the
email address box. It could destroy files on the system as well as search for any
passwords and forward a list of the same to the attacker. Within days it spread to
40 million computers in more than 20 countries causing a financial loss of about $
9 billion.
