About computer virus

What is a computer virus?
A computer virus is a small software program that spreads from one computer to another computer and that interferes with computer operation. A computer virus may corrupt or delete data on a computer, use an e-mail program to spread the virus to other computers, or even delete everything on the hard disk. 

Computer viruses are most easily spread by attachments in e-mail messages or by instant messaging messages. Therefore, you must never open an e-mail attachment unless you know who sent the message or unless you are expecting the e-mail attachment. Computer viruses can be disguised as attachments of funny images, greeting cards, or audio and video files. Computer viruses also spread by using downloads on the Internet. Computer viruses can be hidden in pirated software or in other files or programs that you may download.

About computer Hacker

Hacking developed alongside "Phone Phreaking", a term referred to exploration of the phone network without authorization, and there has often been overlap between both technology and participants. Bruce Sterling traces part of the roots of the computer underground to the Yippies, a 1960s counterculture movement which published the Technological Assistance Program (TAP) newsletter. . Other sources of early 70s hacker culture can be traced towards more beneficial forms of hacking, including MIT labs or the homebrew club, which later resulted in such things as early personal computers or the open source movement.

In common usage, a hacker is a person who breaks into computers, usually by gaining access to administrative controls.The subculture that has evolved around hackers is often referred to as the computer underground. Proponents claim to be motivated by artistic and political ends, and are often unconcerned about the use of illegal means to achieve them.

Other uses of the word hacker exist that are not related to computer security (computer programmer and home computer hobbyists), but these are rarely used by the mainstream media. Some would argue that the people that are now considered hackers are not hackers, as before the media described the person who breaks into computers as a hacker there was a hacker community. This community was a community of people who had a large interest in computer programming, often creating open source software. These people now refer to the cyber-criminal hackers as "crackers".
