A computer virus is a computer program that is created to make and spread copies of itlf. The program may however also be designed to have other effects on the systems it infects, ranging from the annoying to the disastrous.
Virus attacks are growing rapidly the days. According to BusinessWeek, the 76,404 attacks reported in the first half of 2003 nearly match previous year's total number. As new antivirus tools are
more powerful than before, the virus writers are getting a lot smarter with newer and creative ways to attack network systems. Let's first examine some common virus types:
Basic Virus - a piece of software code that is developed to attack computers and network systems via
e-mail or Internet connections. It quickly replicates itlf and gradually attaches to files, programs or the hard drive.
Trojan Hors - This is a program that doesn't replicate when entering a system but can be effectively ud to open 'back doors.' Trojan Hors allow hackers to take control over a particular system or to steal very important data.
Worm - this type of virus is able to spread itlf automatically over the network from one computer to the next. During a worm attack, urs' computers get infected without even having to click open email attachment or any program, etc.
Since it is very difficult to avoid the virus, your best defen is a powerful antivirus program. In order to fight with such virus, the software vendors should focus on making their products more robust.
This may ask for a trade-off between ur-friendliness and curity. In specific cas it may require line-by-line inspection, code retooling and even systems automation to defend the installed programs.

the【8】structure of a program. Debugging is the process of analyzing and locating bugs when
software does not behave as expected. Software testing is a much more 【9】 means of identifying software 【10】 .Therefore, debugging supports testing other than replacing testing.

【14】 of using a computer. Operating systems provide a software 【15】 , on top of which other programs, called 【16】 programs, can run. The application programs must be written to run
