COMMON TYPES OF MALWARE
Home Recent Tabs LESSON
You can type something here…
The computer worms
spread over the computer
networks by exploiting the
computer system
vulnerabilities. They have
the ability to self-replicate
and spread independently.
Often, they are spread
through mass e-mails with
infected attachments to
users’ contacts
WORMS
This is a malware which is
capable of copying itself
and spreading to other
computers. They can steal
information, harm host
computers and networks,
steal money, render
advertisements, and do
other ways to cause
damages.

It is also known as “Trojan”.
To trick the users to
download or install the
malware, it disguises itself
as a normal file or program
TROJAN
HORSE It is a flaw that produces
undesired outcomes which
are usually results of
human error usually exists
in the source code of
compilers of a program.
These can be prevented
with developer education,
code analysis tools, and
quality education

It is a short form of
advertising-supported
software. It delivers
advertisements
automatically such as pop-
up ads on websites and

system. Then, it will display a
display message forcing the
user to pay the malware
creator to remove restriction
as well as to regain access
