Computer Viruses

A Virus is a program that replicates(copies) it self and can cause harm by the following methods:

– Copying files– Deleting files– Corrupting files

Viruses are designed to:– Spy on your online use – e.g. :

• Collect username and passwords• Collect card numbers used for online purchases

– make a computer system unreliable / crash / delete data– copy itself between computers / within one computer

How do we protect against viruses?

Preventing a virus attack

Install anti-virus software. Must be

kept up to date and scan regularly

Do not open email attachments unless you

know the sender

Do not attach portable drives or memory sticks unless they have been

scanned for viruses

Not download games or software from a website unless it is a trusted site

Hacking and hackers

Hacking is the process of gaining unauthorised access to a computer system. Hackers often access computer systems using the internet.

How?– Guess the users password– Install software on the user’s pc without their permission to log

the users key presses(records what you type)

The software is called Spyware or key-logging software

Why do people hack?– To see if they can access a secure system– To commit fraud by changing data etc.– To access confidential information.

How do we protect against hackers?

Purpose of a Firewall

To prevent user accessing a computer or network using

the internet

To prevent undesirable content (e.g. pornography, violent videos etc.) being accessed by users of the

internet.

Use a firewall – a firewall is hardware, software, or both that checks the data being sent or received by your computer either to let it through or block it.
