Viruses

virus

Viruses (vy-rus-iz) are very tiny micro-organisms.

Viruses are even smaller than bacteria.

Viruses can only grow and reproduce inside their hosts.

Humans, animals and plants are their hosts.

Peppers effected by viruses

Most viruses cannot live long outside their hosts.

Some viruses can spread very fast inside our body.

They can make us sick.

Measles, chicken pox, polio, mumps and flu are caused by viruses.

H1N1 virus causes Influenza A(H1N1).

AIDS is caused by HIV virus.

Viruses can also make plants and animals sick.

Viruses also effect bacteria.

Viruses that effect bacteria are called bacteriophage

Anyway viruses that effect plants cannot effect animals and human.

Viruses that effect human cannot effect plants and animals.

We use viruses to make vaccines.

Vaccines help our body to fight diseases.

Anyway these viruses are not the same as computer virus.

Computer viruses are not living things.

How Will The April Fools’ Computer Worm Affect You?

Computer worm is like a computer virus.

A computer worm is not a living thing like earth worm, fruit worm and other worms that lives around us.

The name of this computer worm is Conficker.c.

I read about the computer worm from the CNN news on the internet.

It is supposed to hit computers on April 1.

People may lose their files and programs in their computer.

The bad people who programed the  Conficker.c can know other people’s passwords and can delete our files, folders, games and other things in our computers.

I think that  this computer worm can start a computer virus.

Computer worm can hit your computers on April 1st

(CNN) — Remember the dire predictions surrounding the “millennium bug?” The doom-and-gloom scenarios bandied about by security analysts on how computers could act when their clocks turned to January 1, 2000?

Well, researchers are hoping that a potential April Fools’ time bomb — the Conficker.c that is supposed to hit computers on April 1 — turns out to be equally unfounded.

But realizing that hope alone is not a prudent option, here is a primer on the worm so you can adequately prepare yourself — and your computer.

What is Conficker.c and what do analysts fear it may do?

Conficker.c is a worm, a malicious program thought to have already infected between 5 million and 10 million computers.

Those infections haven’t spawned many symptoms, but on April 1 a master computer is scheduled to gain control of these zombie machines, said Don DeBolt, director of threat research for CA, a New York-based IT and software company.
