Computer Virus
If programs or data has suddenly been destroyed, if an unexpected
operation takes place or if an abnormal display appears on the
screen, your personal computer may have been infiltrated by a
computer virus. The computer virus is a rogue program that secretly
invades a personal computer and operates it willfully while
destroying memorized data.
A program for eliminating the virus is called vaccine program.
There is a possibility of contamination with a computer virus by
downloading through communication a program including a
computer virus, or by using an exchangeable recording medium
such as a floppy disk that contains a computer virus. Also, it is
possible to transmit the virus from one personal computer to another
via communication or recording media.
So avoid using a program
or recording medium that might include a virus
.
Carry out check using a vaccine program if there is a possibility of
contamination with a virus. But depending on the type of vaccine
program, it may be impossible to eliminate the virus.
It is therefore recommended to back up the contents of the
hard disk beforehand
.
Note that the preparation of a vaccine program and the elimination of
a computer virus must be carried out by the user.
Power Failure
A power failure or momentary voltage drop of the power supply due
to lightning, etc. may cause failure of the personal computer used
with the instrument and also damages the system software,
application software and other data.
To avoid such problems,
it is recommended to use an AC
uninterruptible power source
