A computer virus is a malware program that when executed replicates by inserting copies of itself into other computer programs, data files. When this replication succeeds, the affected areas are then said to be infected. Viruses often perform some type of harmful activity on the infected hosts such as accessing private information, corrupting data or even rendering the computer useless. However, not all viruses carry a destructive payload or attempt to hide themselves.

Software designed to infiltrate a computer system and possibly
damage it without the user’s knowledge or consent
Types of malware
Viruses
Adware
Spyware
Trojan Horse
Worms
Ransomware
Logic Bombs…and more…
3. Spyware
Malicious software that is either downloaded unwittingly from a
website
or is installed along with some other third-party software
It monitors the user’s activity without informing the user that it is
doing so
It passes on user’s information to marketers or intercepts personal
data such as credit card numbers
It always provides commercial gain
4. How Spyware comes to your computer?
Downloading free games, utilities, media players
Opening spam email
Visiting corrupted websites
Mainstream software applications
File sharing programs
5. How to prevent Spyware?
The first line of defense is Windows defender (Windows 8)

Follow your instincts, don’t visit untrusted Websites
Read before you click, uncheck the small boxes, and “No, I do not accept”
6. Adware
Displays ads and generate revenue for the creator
Adware collect data on which sites the user visits
Sends this data back to the company and delivers ads based on the
information
It can be included within some freeware or shareware
A visit to an infected website can result in installation of adware
Antivirus software can detect and remove adware
7. Trojan Horse
Trojan horses are programs that enter a system or network under the
guise of another program
It may be included as an attachment or as part of an installation program

of a virus
Worms spread from computer to computer, but unlike a virus, it has the
capability to travel without any human action
A worm takes advantage of file or information transport features on your
system, which is what allows it to travel unaided
Worm has the capability to replicate itself on your system
So your computer will be sending out hundreds or thousands of copies of
itself creating a huge devastating attack effect
12. Ransomware
Ransomware is often delivered through Trojan Horse
Takes control of the system and demands a third party be paid
Control can be accomplished by encrypting the hard drive, by changing
user password information or any other creative ways
Users are assured that by paying the money they will be given the code
needed to revert their system to normal operations
14. Logic Bombs
Logic bombs are programs that executes when a certain predefined event
occurs
A bomb may send a note to attacker when a user is logged on to the
Internet
This message informs the attacker that the user is ready for an attack
