Computer Virus and Virus
Scan{{/B}}
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.
Many anti-virus products, such
as Virus Scan, hold up the list of proper precautions. S
