m To avoid compatibility problems, be sure to use only one
virus-detection program at a time.
m If your computer is on a network or if you use a modem,
check for viruses each time you copy information from
an outside source.
m If you give information to other computer users on disks
or send information electronically, make certain that there are
no viruses on your computer system before distributing the
information.
m Make sure that you have a virus-free copy of your System
Folder on floppy disks. Back up your System Folder
immediately after you install new system software—before
you install other software or open any programs.
Working with several programs at a time
You can open as many programs and desk accessories as your
computer’s memory allows.
All open programs are listed in the Application menu at the right
end of the menu bar. The name of the active program (the one
you’re using right now) has a checkmark next to it, and its icon
appears in the menu bar.
Finding out what programs are open
If you have several programs and windows open, you can find out
which program is active and what other programs are open by
pulling down the Application menu.
