A self-starting program designed to incon-
venience you. Virus programs have been
known to corrupt the files stored on a
hard-disk drive or to replicate themselves
until a computer or network runs out of
memory.
The most common way that virus pro-
grams move from one computer to
another is via “infected” diskettes, from
which they copy themselves to the
hard-disk drive. To guard against virus pro-
grams, you should do the following:
Periodically run a virus-checking util-
ity on your computer’s hard-disk
drive
Always run a virus-checking utility on
any diskettes (including commer-
cially sold software) before using
them

system. When you start Windows, it con-
sults the win.ini file to determine a variety
of options for the Windows operating en-
vironment. Among other things, the
win.ini file records what printer(s) and
fonts are installed for Windows. The
win.ini file also usually includes sections
that contain optional settings for Win-
dows application programs that are
installed on the hard-disk drive.
