What is a virus
Malware(short for malicious software) is computer programs designed to infiltrate and damage computers without the users consent. Malware is a general term covering all the different types of threats to your computer safety(such as viruses, spyware,worms, botnets, and all types of these threats).

These threats can cause

-Corrupt computer operation

-Gather sensitive information

-Gain access to private computer systems

To prevent these threats you need to find what is its name and follow the procedures to solve the solution.
Spams is flooding the internet with a large number of copies of the same message, in an attempt to force the message on people who would not choose to receive it. Most spams is from

-Commercial advertising

-For dubious products

-Get rich quick schemes

-People sending messages for their enjoyment to annoy you

Spam is annoying,but harmless. however, some spam is part of an identity theft scam or other kind of fraud. You can also ge text message spam, instant message spam, and social networking spam.

What are spams
A computer worm is a self-replicating, malware program. Not like a virus, it does not need to attach itself to an existing program or need user
intervention to spread. It uses a network to send copies of itself to other computers on the network.

Worms can cause two types of damages to the network:

-Damage to the network: by their replicating behavior, worms can cause bandwidth and can cause degraded network performance.

-Payload: worms also deliver payloads such as backdoor that allows hackers to gain control of the infected computer. That computer can then become a part of a botnet used to send spam or launch Distributed Denial-of-service(DDos) attacks (often coupled with blackmailed attemps)
What is a computer worm
A virus is a malware program that when executed it replicates by inserting copying of itself into other computer programs, and data files. They can perform types of harmful activity
on infected hosts, such as

-Stealing hard disk space or CPU time

-Accessing private information

-Corrupting data

-Displaying political or humorous messages on the users screen

-Spamming their contacts

-Logging their keystrokes

A computer virus can also corrupt or delete data on your computer, use your email program to spread itself to other computers or erase everything on your hard drive.

How to prevent a virus
-Set up an antivirus program for your computer:Use an antivrus program such as nortorn antivirus, microsoft virus protection

-Download files from trusted sites only: If you download a program or data file from the internet or other shared networks, viruses may be transfered to your computer. sometimes the free softwhere programs on the internet have viruses especially if you are downloading from sources such as torrent newsnet newsgroups

-Dont forget to do a virus scan for them after peripheral devices are connected to your computer: Devices such as MP3 players, USB thumb drives, memory cards or CD drives are also means of spreading viruses

How to prevent a spam
There is no way to prevent a spam by using programs, but there are some precautions that can be taken to reduce the likehood of spammers getting your email.
- Be carefull to who you give your email to. This includes to websites and anyone you want to email

-Make sure your computer s on your network are virus and malware free

-Use secure passwords for your email and hosting account to prevent to prevent hackers from gussing and logging in

-Do not put your e-mail on websites where the public can see it

-If frends are sending you messages sent to a large recipient list, convince them to use BBC insted og TO or CC, this prevents people from seeing your email address; or request they stop including if you do not want to recieve the messages

A botnet is a type of malware that allows the attacker to take over an infected computer. Which are also known as "Web robots" they are usually part of a network of infected machines, known as "Botnet", which is typically made up of victom machines that stretch across the globe. (since a bot infected computer does a bidding to its master many people refered theses victom machines as zombies).

After a computer is taken over by a bot it can be used to carry out a variety of automated tasks, such as

-They send spam, viruses, and spywhere

-They steal personal and private information and send it back to the malicious user(credit card numbers, bank credentials, and other sensitive personal information).

How to prevent botnets
-Make sure to use encryped password protection for your home and office network

-Install a firewall to prevent hackers and keep an eye on your network traffic

-Use reliable antivirus and spyware detection applications.

-Dont click on random web links to sites you've never heard before

-If a pop-up window comes on that tells you to download a antvirus or says your a winner dont click them(most of the times these pop-ups are scams and clicking on themcould install malware on your computer)

How to prevent computer worms
-Be careful and aware of what emails your getting; there are alote of junk and spam email that contains viruses and worms that ends up directly in your inbox. So you need to be careful on who sends them and think twice before opening them

-Update your anti-virus software; be sure that you are using the most up-to-date version software, so it can catch all those new viruses and worms

-When you use email programs be sure to use the ons with built in spam file. This way not only will be tracked and filtered for viruses, but you will also feel secure that your computer is free from worms and viruses

What is malware
The new privacy law stated that all its clients will have all their personal information protected from computer threats and hackers. It will do all this by offering programs such as "Nortorn Anti-virus" or "Microsoft Anti-Virus", and creating web sites that will tell you how to deal with threats. For securing presonal information,the websites they stor it on is fully secured by their own servers and prevents hackers from getting in.
E- communications(short for electronic communication) are safe and secured by thier servers. However the server can't be hacked, but your profile can be. Once they get in they can post anything online and get your private information. If this is the case you must report it before it is too late. Also if you can still be at risk by the person who you are talking to(ex. if you are on a facebook page about bussiness and you are descussing to your group and some of them are not the guy they can get the information there).
