This presentation will focus on malware
which are the most destructive threats
to your computer.

COMPUTER VIRUSES
Software that replicates by inserting copies of itself into other
computer programs in order to perform some type of harmful
activity such as sending out bogus emails.
Example:
Melisa Virus
Targeted at Microsoft Office files. It generates emails to send to
email contacts stored in Microsoft Outlook.

WORMS
Worms are similar to viruses in that it replicates on to other
computers but usually targets networked computers in order
to overwhelm the network. For example: requesting the
same webpage thousands of times causing the network to
crash.
Examples: The Flame Worm
Usually targets corporations and government websites

Slide 6
TROJANS
A non-self-replicating program typically causing system
malfunction. In some cases Trojans can also steal data.
Usually runs in the background so the user is unaware.
Example: System Crash Trojan
A Trojan that targets and corrupts the most important
system files causing the system to malfunction.

Slide 7
SCAREWARE
Software with the malicious and unethical intent of selling consumers
something that is presented in a manner that causes shock, anxiety,
or the perception of a threat.
Also known as Ransomeware.
For example: You may receive an unsolicited message from some
type of “security software” that deceives users into buying the
software in order to remove a fake malware threat.
Slide 8
SPYWARE
Spyware collects information stored on the computer, then
sends that information to another entity. The information is
gathered without the user’s knowledge.
Spyware such as keyloggers, can be the most damaging
because it can be used to collect everything typed on a
keyboard, including credit card numbers, passwords, social
security numbers, etc.
Slide 9
ADWARE
Adware is the name given to advertising supported software
which in itself is not illegal and usually is not harmful (other than
being annoying) to the end user.
Even legitimate adware can however pose a privacy risk to users.
Adware survives by serving advertisements to the user which
allow them to offer software or utilities to the user for free.

BROWSER HIJACKERS
The modification of a web browser's settings. The term
"hijacking" is used as the changes are performed without the
user's permission.
A browser hijacker may replace the existing home page or
search page with its own. Babylon Toolbar, Conduit Search
and Onewebsearch are common browser hijackers.

Slide 11
WHY DO PEOPLE CREATE MALWARE?
To take control of a computer and
use it for specific tasks
Why do People Create Computer
Viruses?
To generate money
To steal sensitive information
(credit card numbers, passwords,
personal details, data etc.)
To prove a point, to prove it can be
done, to prove ones skill or for
revenge purposes
To cripple a computer or network
Slide 12
HOW CAN I PROTECT MY COMPUTER
FROM MALWARE?
There is no 100% assured
method of protecting your
computer.
You can reduce most of
the risk by installing antimalware monitoring
software;
however, the software can’t
do it all.
Just as important in

“FREE” SOFTWARE
•
“Anything that looks too good to be true, usually is too good to be true”
-Anonymous
• Some programs attempt to install malware as a part of
the installation process for a “free” software program.
• Before installing any free software, search the web to be
sure you’re installing malware free software.
• Take a couple of seconds to scan the EULA (End User
License Agreement) for anything that suggests other
programs may be a part of the installation.

EMAIL
E-mail Attachments
• You cannot get malware by simply reading an email. The
problem is the ATTACHMENT.
• Only open attachments from trusted sources.
Beware of Phishing Emails
•
•
A phishing email looks like it comes from a well-known
organization, like PayPal, Amazon, or a national bank,
containing a malicious attachment or a link for you to click
which will open the door to an infection, or worse.
Never use email links to access your accounts.

POP UP WINDOWS
Pop-ups
• Whenever you’re browsing the web and see a pop-up
message appear, exercise extreme caution: pop-ups are
a favorite means of delivering viruses.
• A favorite tactic of hackers is generating messages that
pop up and look legitimate, such as your Flash player is
out of date and needs an update, prompting you to click
for the update. DON’T DO IT.
• Never trust a pop-up that says you’ve been infected with
something and to “click here” to install a program “to get
rid of it”.

WHAT PROGRAMS DO I NEED TO
PROTECT MY COMPUTER?
For computers running Microsoft Windows there are 2
programs that can be run simultaneously. Both are free.
Windows 7 – Microsoft Security Essentials

LETS SUMMARIZE
•
• Antivirus and antispyware monitoring software by itself
will not provide 100% malware prevention.
• Your vigilance and attention must be part of the
overall prevention.
