Computer viruses have been around for many years so let’s take a look at the top 10
scary and dangerous computer viruses.
Alright starting us off in at number 10 with Melissa (1999).

to be a list of passwords for porn websites.

computers.

address book which would cause a lot of buffering and email traffic.
This virus also disrupted a lot of email services of government agencies and corporations.

and restoring data.
Number 7 brings us to Code Red (2001).
This virus first made an appearance in 2001 and it targeted computers that were running
the Microsoft IIS web server.
Once your computer becomes infected, it will make a hundred copies of itself and it will
duplicate even more until it eats up a lot of your computers’ resources, making your
computer unusable.

on memory.
It is estimated that between 1-2 million people were affected and it caused over 2 billion
dollars worth of damages.
Conficker is in at number 6.
This virus has been ruining computers since 2008 and it infects computers by using flaws
in the operating system to create a botnet which is a bunch of computers that are controlled
as a group without the owner’s knowledge.

to reset your accounts, block access, turn off services and lock you out.
It would even install software that uses scareware in order to scam money off of the user.

for it.
Prepare yourself in at number 5 we have Storm Worm (2007).

batters Europe.”
People who opened this attachment would immediately become infected and it would wreck havoc on
your computer.

billion dollars in damage and it infected about 2 million computers from all over the
