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.
