Common Confusion
Many people sometimes confuse viruses, trojan horses and worms to be the same thing Indeed they may be similar, but all 3 do
different things. Knowing the difference between the 3
may help you better protect your computer from their damaging effects

Viruses
A virus is a program or piece of code that is loaded onto your computer without your knowledge and runs against your wishes.
Almost all viruses are attached to an executable file, this means the virus may exist on your computer but it actually cannot infect your computer unless you run or the program.
It is important to note that a virus cannot be spread without human action, (such as running an infected program) to keep it going.

Worms
Considered to be a sub-class of a virus.
They spread from computer to computer but unlike viruses they DO NOT need human action to travel.
The biggest threat of the worm is its capability to replicate itself and sending out thousands of copies of itself. In most cases the worm consumes way too much
memory causing web and network servers to stop responding

Trojan Horse
A destructive program that acts as useful software but will do damage once installed and ran on your computer.
Unlike viruses, Trojan horses do not replicate themselves
The Damage varies depending on the design: Some will change your desktop or add silly
icons Others will delete files and destroy
informations

Trojan Horse (contd.)
The worst part of a Trojan horse is that some will create a “backdoor” to your computer that will gives any user access to all your information This can lead to the compromisation of
confidential and personal files.

Protecting Your Computer
The first step, is making sure your Operating System is up to date.
You also want to make sure you have an antivirus while frequently downloading updates to ensure that your antivirus can fix the latest viruses, trojan horses, and worms. Purchase an antivirus that can scan emails
and downloaded files from the internet.

Protecting Your Computer
Not only do you need to have an antivirus downloaded and running, you also need a firewall as well. This prevents unauthorized use and access to
your computer. Can be either hardware or software
Usually software can protect you in more ways than hardware.
Keep in mind, these options won’t fully protect you but will offer much needed security.
