understanding their unique
characteristics and how they
operate.

malware attacks and maintain the
safety of digital devices.

Success Criteria

features of different types of malware
and their potential impact on devices.

• I can list and implement strategies to

protect my device from malware and
seek guidance when uncertain about
digital safety.

Staying safe in the digital world

●
We protect ourselves from danger and
harm in lots of different ways.

●
If it's freezing outside, we protect ourselves from the cold
by wearing a warm coat.

When crossing a busy road, we always use crossings or
look for a safe place to cross.

What do you mean by hardware and software of a computer? can you give an example of each?

Hardware and software

•Hardware is the physical parts of the device, that we
can see and touch (including the inside of the
computer).

•Devices are made up of two separate
parts - hardware and software.

• The software is the information and programs stored

inside the computer's memory.

• We can protect the device's hardware by keeping it in a

protective case and being careful not to scratch or
damage it when we use it.

• Even if we keep the hardware safe, the

software might still be in danger.

Do the devices can also be attacked by viruses?

• Yes

• No

Dangerous software programs

• There are harmful programs called malware

that can damage the software inside
a digital device.

• It does this by attacking the software that

makes your device not to work properly.

• The word malware comes from combining

the words malicious (meaning harmful)
and software (meaning program).

Dangerous software programs

• When a device is being attacked by

malware, we say that it is infected.

• Malware will often try to spread to other

computers and devices using the internet.

• It might become part of an email message

attachment or pretend to be a photo or
document that you are sharing.

What different types of malware are

there?

Viruses

•A virus is a type of malware that spreads by attaching
itself to other programs.

•It's named after the viruses that make people ill, like
the common cold.

•Once your device has a virus it may spread quickly to
other devices, when you are connected to the
internet.

Viruses

•A virus can secretly attach itself to an email. This way it
can spread to your friends and family when you send
them a message.

•It can also copy itself onto a memory stick and infect
another device that way.

Worms

• Worms can spread from device to device.

• Unlike a virus, they don't need to attach themselves to

other programs.

• Worms can copy themselves hundreds of times, so they

can very quickly harm your device.

• A worm might copy itself onto your email account and

send a copy of itself to all of your contacts!

Trojan horse

●
A trojan horse (or just a trojan) pretends it
is a safe, useful computer program.

●
It will, however, try to attack your device.

●
Trojans are named after the Ancient
Greek legend of the Trojan Horse.

Spyware

• Spyware is malware that steals personal

information about the user like:
• usernames
• passwords
• email addresses

• It does this by keeping a record of everything the user

types, which is called key logging.

• Some spyware can even use your webcam without your

knowledge!
