Computer Security

Computer viruses are small software programs that are

designed to spread from one computer to another and to

interfere with how a computer works

A virus might corrupt or delete data on your computer, use your e-

mail program to spread itself to other computers, or even erase everything on your hard disk.

Some viruses can prevent you from being able to use your

computer at all.

Some viruses can delete your files on your computer, or even erase everything in

your whole hard-drive!

Some viruses do nothing harmful at all. There have been many viruses that

spread themselves without doing anything dangerous. But they are still known as

viruses because they access your computer without

consent.

When you get a computer virus your computer may get random

pop-ups trying to make you download something or sell

something to you. It can also spread itself across your P.C files

and make it harder for you to remove it.

To prevent your computer getting viruses, you should download anti-virus software and scan your files

regularly for viruses.

Viruses can be disguised as attachments of funny

images, greeting cards, or audio and video files.

A hacker is someone who accesses someone else’s computer files and their information without their

permission

To stop someone from hacking your computer you

could install a firewall, which stops them gaining access

to your systemOne easy way to stop your computer from being

hacked, is when you are not using it, turn it off or

disconnect it from the internet

By gaining access to someone else’s data without permission is committing a

criminal offence

If someone where to hack your account, I could mean big trouble. They can read

your private messages, send out spam or make your

messages public.

There are many famous hackers, one of them us

Matthew Anderson, who was jailed for 18 months after he hacked millions of people’s

e-mail account

A firewall prevents unauthorised intrusions into your computer system and

controls and allows and only allows authorised access

A back-up is when you copy all of your data to another

area such as a memory stick or a CD in case all of your files are deleted. More and

more people are using computers to store

memories, important documents, other bits of

information that may need to be kept for long periods

of time. Backing up a computer is essential for

keeping documents around.

If you are using anything such as a memory stick or CD to back up- your files, make sure they are away

from your computer and not left plugged in then whoever gets onto your compter can

access it
