Computer users are advised to adopt good computing practices to keep their computer virus-free. "Protecting our computers against virus attacks is very important nowadays when computers are commonly and widely used in our home and offices." said a spokesman for the Information Technology Services Department (ITSD).
    "Typical payload of computer virus can range from cresting annoyances such as affecting the mouse, keyboard or other computer functions, to more destuctive actions like modifying or deleting files, or exposing secret information from the hard disk of the victim’s computer." Some computer virus may format the hard disk to corrupt all data stored inside the computer.
    "Besides, there are also computer viruses that will create mass mailing or scanning traffic not only to turn infected computers into a platform for launching further attacks to other computers, but also to consume mailbox storage and network bandwidth."
    "As a result, the network and computer systems will be overloaded and the normal operation of the network and computer systems will be seriously affected." said the spokesman.
    He noted that the impact was particularly singnificant due to the current highly interconnected computer notwork environment." To avoid such inconveniences and losses, we should take effective computing practices to prevent our computers from virus infections .In fact, such practices are simple and easy." said the spokesman.
