- Malware
- Malware is the term for any computer program installed either
deliberately or accidentally on a computer with the intention of
causing harm. The most common types of malware are
- Viruses: these are programs designed to disrupt the workings of a computer.
They are called viruses because they are designed to be spread from one
infected machine to another. Viruses can be downloaded from websites or
installed by opening a file attatched to a SPAM email.
- Spyware: this is software designed to monitor the ways the computer is used and then
report this back to someone. One example is keystroke software - this could be used to
record someone's password being typed into a bank website.
- Adware: this is software designed to monitor your
internet use and then display adverts based on your
web-browsing habits. Some software producers
include adware in their programs as a way of
getting back some of the costs of developing their
products. Many people believe that adware is an
invasion of privacy.

to be from your bank or other business, requestiong

a fake and the owner will use the data they collect from
you to hack into your real bank account to withdraw
money. Phishing emails are examples of SPAM.
