what is a computer virus?
A computer virus is a man-made computer code that disrupts a computer's
functionality by infecting its system and destroying data. It can be transmitted
to your computer via an infected floppy disk or over a network, such as the
Internet, when you receive e-mail or download a software program (known as
"shareware") from a web site.
About 16,000 viruses have been identified by experts and approximately 1000 of these are actively "in the wild." However, according to research, about two-thirds of all infections are caused by the same 10 viruses.
how does a virus affect the way my computer functions?
A virus disables your PC by reproducing itself either in your
computer's memory (RAM) or on the hard drive. A virus can remain on a computer's
hard drive even after it has been reformatted. Sometimes, a virus remains hidden
and expands invisibly or quietly deposits itself in a document. This is called a
stealth virus.
Your computer may have contracted a virus if one or more of the following symptoms appear:
If your computer is experiencing any of these problems, try rebooting it. If it is still experiencing the problem, contact your computer retailer.
what can I do to prevent my computer from contracting
a virus?
Using an anti-virus program is the best way to keep your computer
healthy and virus-free. Anytime you try downloading software, either from a
CD-ROM or the Internet, the program will automatically scan the software to see
if any viruses exist. Two popular anti-virus programs are Norton AntiVirus and
McAffee VirusScan.
When buying software, do a bit of homework first and use a reputable software dealer. Be careful how you use and trade CD-ROMs and floppy disks with friends and family. Also, be careful when downloading inexpensive "shareware" from the Internet. If you have any questions regarding purchasing software, contact your local retailer.
can a virus affect any other equipment attached to a
computer?
Even though a virus usually affects only software, it can cause problems with
different hardware devices attached to a computer. A virus can cause printing
problems, interfere with the keyboard by displaying multiple characters when
only one key has been pressed, or cause random and unexpected accessing of other
drives.
