Since the beginnings of the computer and internet, viruses have also coexisted with us. Like biological viruses, they are unwanted parasites, and often inflict damage to computers internally. The damage they inflict can vary, but like biological viruses, they are also many cures available. Programmers have developed firewalls, virus detection programs, and anti virus programs to combat this menace. Sometimes these defenses are not enough, because like true viruses, they can evolve and change (polymorphic). The only difference that they withhold from biological viruses is that they are all man made.
The "Fantastic Four" of viruses are:
|worm||A program or algorithm that replicates itself over a computer network and usually performs malicious actions, such as using up the computer's resources and possibly shutting the system down.|
|social engineering||In the realm of computers, the act of obtaining or attempting to obtain otherwise secure data by conning an individual into revealing secure information.|
|attachment||A file attached to an e-mail message. There are a number of encoding schemes, the two most prevalent being Uuencode and MIME.|
|Short for electronic mail, the transmission of messages over communications networks.|
|anti-virus software||Software tools for detecting, blocking and/or removing viruses from files, emails or network communications.|
|hoax||The most common hoax, however, is the hoax virus. This usually consists of an email message warning recipients about a new and terribly destructive virus. It ends by suggesting that the reader should warn his or her friends and colleagues.|
|payload||This is the malicious activity that the virus performs. Not all viruses have payloads, but there are some that perform destructive actions.|
|virus||A program or piece of code that is loaded onto your computer without your knowledge and runs against your wishes. Viruses can also replicate themselves. All computer viruses are manmade.|
|zombies||Zombies may remain dormant on your computer system for an extended period of time. They are normally programs used by hackers in a coordinated attack on a system. Transmitted through E-mail.|
