Computer Viruses’

1.a)  A computer virus also known as a computer worm is a standalone malware computer program that replicates itself in order to spread to other computers. It often uses a computer network to spread itself, relying on security failures on the target computer to access it. Unlike a computer virus, it doesn't need to attach itself to another program. Worms will almost always cause at least some harm to the network, even if only by consuming bandwidth, whereas viruses almost always corrupt or modify files on a targeted computer. http://en.wikipedia.org/wiki/Computer_worm
b)  A Trojan horse virus or Trojan, in computing is a generally non-self-replicating type of malware program, containing malicious code that, when executed, carries out actions determined by the nature of the Trojan, typically causing theft or loss of data, and maybe possible system harm. The term is derived from the story of the wooden horse used to trick defenders of Troy into taking concealed warriors into their city in ancient Anatolia, because computer Trojans often employ a form of social engineering, presenting themselves as routine, useful, or interesting in order to persuade victims to install them on their computers.

c)  Spyware is software that aids in gathering information about a person or organization without their knowledge and that may send such information to another entity without the consumer's consent, or that asserts control over a computer without the consumer's knowledge.

d)  Rogue-AV or rogue security software is a rogue (a form of Internet fraud using computer malware) that deceives or misleads users into paying money for fake or simulated removal of malware (so is a form of ransomware) — or it claims to get rid of, but instead introduces malware to the computer. Rogue security software has become a growing and serious security threat in desktop computing in recent years (from 2008 on).  http://en.wikipedia.org/wiki/Rogue_security_software

5. An e-mail virus is computer code sent to you as an e-mail note attachment which, if activated, will cause some unexpected and usually harmful effect, such as destroying certain files on your hard disk and causing the attachment to be remailed to everyone in your address book. Although not the only kind of computer virus, e-mail viruses are the best known and undoubtedly cause the greatest loss of time and money overall. http://us.wow.com/search?s_pt=aolsem&s_it=aolsem&s_chn=9&q=what%20is%20an%20email%20virus
Most spam is irritating and time-consuming, but some spam is positively dangerous to handle. Usually email scams are trying to get you to give up your bank details so that the fraudsters can either withdraw money, or steal your identity.

6.There are hundreds of thousands of viruses out there (if not millions) and they often designed for different objectives. Most of them fall under the following categories:

* To take control of a computer and use it for specific tasks
* To generate money
* To steal sensitive information (credit card numbers, passwords, personal details, data etc.)
* To prove a point, to prove it can be done, to prove ones skill or for revenge purposes
* To cripple a computer or network
