#1 Beast Trojan Horse

This virus can become the controller or your computer when activated

and access any file on your computer and it can upload, download, or delete

anything on your computer. It also has control over any power option and any

password that you have ever typed in. It can also hack into your webcam and

also can take a screenshot at any time.

This virus was found in 2002.

#2 SQL Slammer

This particular virus is file-less worm that isn't saved as a regular file. It

saves itself in the WINDOWS folder and saves itself as a normal windows file.

In the first ten minutes it affected the 359,000 hosts around the world. It caused

about $950,000 and $1.2 billion in productivity lost in its first five days through

out the world.

This virus was found on the 27th of January in 2003.

#3 MyDoomThis is a virus that spreads via email. This virus is a worm that holds

the world record for the fastest spreading mass mailer worm. It is an email that

has a attachment that apparently contains the message for the email. The virus

is in the attachment and when people try to open the attachment they find

nothing and move on. Once this attachment is opened it goes into the hosts

computer and starts messing things up. Also once this is in your computer it

copies itself and sends itself to everyone in the hosts address book.

This worm was first discovered on January 24th 2004.

#4 Bandook Rat

This virus resembles the Beast Trojan Horse but is also a little different.

The RAT is short for Remote Administration Tool. It is named this because it

can access files remotely just like the first virus but this one effects almost any

Windows computer ever made. That means that it is being altered for Windows

7 & 8.

This virus was found in the year of 2005.

#5 BlackwormThis is also a virus that is spread via email. This virus is special

because it uses an external engine that runs the virus after the email is opened.

It sends itself by email but alters itself every time that it is sent. It come with

different subjects, body text or attachment names. After it saves itself to the

hard drive of the computer it corrupts the computer on the third of every month.

The really bad part about this virus is that it can uninstall your anti-virus unless

it is installed in a certain place in your computer. This means that when you

restart your computer it wont work right and your computer wont be protected.

This worm was found on January 20th 2006.
