What is a Virus?

• A virus is a program that is designed to infect a
  host computer and spread to any computer it is
  executed on.

3
Types of Viruses

• Macro Virus- These types of viruses load
  themselves into the templates used in common
  Microsoft office products. These include Word,
  Excel, and PowerPoint. They are loaded onto the
  computer anytime the saved document or file is
  opened.
• Program Virus- These viruses attach themselves to
  executable files and load themselves onto the
  computer when the setups are launched.
• Boot Virus- These viruses load into the boot
  sector of the hard disk drive when the system is
  being booted from a boot disk.

How do they begin infecting?

• A virus is loaded onto a computer through opening
  downloaded and transferred files.
• Anytime a file containing a virus is opened on a
  computer, the virus begin to infect the computer
  it was loaded on.

5
Virus Myths

• The majority of computer users believe that a
  virus can infect a computer by opening an email.
  This is not true. It can only begin infecting a
  computer when a file attached to the email is
  opened.
• It is also believed that a user can put the
  computer at risk by viewing a website. This is
  also not true. A file must be run or opened in
  order for the virus to begin its infecting.
• Computer users also often believe that by
  downloading a file a virus has infected their
  computer. This is also not true. A file must be
  opened or run before the virus can begin
  infecting.

What is Spyware, Adware, and Malware?

• Spyware is a piece of software that is used to
  change the way a computer is setup, to track web
  surfing habits for advertising purposes, and is
  also used to collect personal information.
• Adware is a piece of software designed to hoard
  your computer with advertisements. Can often slow
  web surfing down to a crawl. It can also use RAM
  space and CPU cycles.
• Malware is almost synonymous with spyware and
  adware. However, it tends to have a more
  malicious intent to it.

10
How Are They Contracted?

• Adware is often loaded through shareware.
  Shareware software developers are often paid to
  include adware. It is also often contracted
  through advertisements.
• Spyware is loaded through opening downloaded
  applications, through browser plug-in
  installations, and through clicking on
  advertisements.
• Malware is contracted through the same methods as
  spyware and adware.

13
How to protect against phishing

• The best way to start protecting yourself is to
  use the keyboard to type in URLs instead of
  clicking on links.
• Try to use websites that have a logo of a lock on
  the bottom of your browser window. It is not
  placed on the website.
• The last way to protect yourself is to use
  security software that blocks against phishing.

14
Other Risks

• Computer users also have to protect themselves
  from hackers.
• To achieve this protection, computer use a piece
  of software or hardware called a firewall.

15

• Firewalls were created to prevent the intrusion
  of another person on a personal computer. They
  were also created to stop computer hackers from
  taking control of a persons computer.

16

  Internet Security software.

  companies such as D-link, Linksys, and Netgear.
