9 Computer viruses are a constant

threat to

companies and

other

organizations

as

well

as

home

users.

Work

in

small

groups

and have a discussion about how computer viruses spread and

how companies should protect against computer viruses.

Computer

viruses

can

be

transmitted

via

e-mail

attachments.

They

also

spread

through

software

downloaded

from

the

Internet.

So

when

you

are

downloading

the

unlicensed

and

pirated

software,

you are likely to put your computer at risk. The software can

seem harmless enough, but they could easily be harboring a

dangerous virus.

To

protect

against

computer

viruses,

we

should

be

careful

when opening e-mail attachments and downloading software. We

should use anti-virus software and update it regularly.

As for companies, they should not only take measures by

investing

in

anti-virus

software,

but

also

pay

enough

attention

to the education of their employees. While the employees may

4

suddenly become aware of the virus threat when the threat is

there,

they

soon

forget

about

it

as

the

stories

disappear

from

the

news

headlines.

So

it

is

important

that

companies

constantly

educate

the

users

about

the

virus

threat

and

ask

them

to practice safe computing.

10 Write a paragraph of around 80 words explaining that

companies should do more than invest in anti-virus software

to

protect

against

computer

viruses.

The

following

points

may

help you to organize your writing. And the first sentence has

been written for you.

To protect against computer viruses, companies should do

more

than

invest

in

anti-virus

software

on

the

desktops,

servers

and

email

gateways.

It’s

true

that

anti

-virus

software,

updated regularly, can protect the companies’ defences to a

large

extent.

The

employees,

however,

may

use

office

computers

for

personal

amusement.

When

they

are

opening

unsolicited

attachments

or

downloading

unauthorized

software,

they

probably are putting the company at risk, for the attachments

and

the

software

could

easily

harbor

dangerous

viruses.

Therefore,

it

is

very

important

that

companies

should

constantly educate their employees about the virus threat and

remind them about what would happen if they let their guard
