What Is Malware?
You have probably heard computer people talk about Malware
and the damage it can cause. I recently realized that
those outside the computer industry are not always familiar
with the word. So here is my answer to the frequent
question, "What is Malware?"
First, the word "malware" is formed from the words
"malicious" and "software." Malware, then is software that
performs malicious activities on a computer system, usually
without the knowledge of the computer owner or user.
Calling something "malware" presupposes a harmful intention
on the part of the creator or sender of the software.
Malware can harm individual computers, networks or servers.
Second, "malware" is a broad term that includes a number of
tactics used to do harm to a computer. It includes computer
viruses, worms, spyware, Trojan horses, and dishonest ads.
For example, there are now images in advertising (e-mails,
newsletters, etc.) that are activated when the
communication is opened. Embedded in the images are codes
that gather information from your computer and report it
back to the sender. Some service providers have now begun
to block all images from e-mails.
Third, "malware" is the same as a "computer contaminant" –
a phrase used in the legal codes of several states,
including California.
Fourth, defective software is not malware. Although
defective software can damage a computer or a network, the
manufacturer's intent is not to do harm.
Malware can affect or be aimed at any single computer or
any type of system such as a network, an application, or an
operating system. What makes a computer vulnerable to
malware?
• When all of the computers in a network operate on the
same operating system, all of the computers in the network
are vulnerable if someone breaks that system.
• Bugs or errors in a system make it easier to exploit with
malware.
• Hidden codes from internet sites, e-mails, CDs or other
disks can introduce malware without the user realizing it.
• Inappropriate changes to the internal structure of the
system.
• Inadequate system security that allows access to
unauthorized persons.
You can be proactive in protecting your computer or system
from malware. The primary elements of malware protection
are:
• Keep all software current and properly patched
• Update your operating system regularly
• Update your anti-virus software regularly
• Download files only from reliable known sources
• Read all license agreements carefully before installing
new software. Look for warnings about spyware.
• Install and use a firewall.
• Allow only the experts to modify code or make changes to
the structure of the system.
If the smooth and efficient operation of your computer or
your network is important to you, it is important to
remember that many damaged files and programs can never be
repaired or recovered if attacked by malware. Protect your
system, protect your programs, protect your files.
