Computer Virus and Virus Scan
A computer virus is a software program that attaches itself to another program in computer memory or on a disk, and spreads from one program to another. Viruses can damage data, cause computers to crash, display offending or bothersome messages, or lie dormant (保持静止的状态) until such time they are set to "awaken". In today’s industry, scanning is no longer considered to be an extravagance--but a necessity. Computer viruses no longer attack your computing environment only but all other computing environments which you contact. Computer viruses can attach themselves to the files being used and later propagate (复制) themselves through disks and files. Important information and hardware losses could plague (瘟疫,烦扰) your computing environment should you not take the proper precautions.
