Checking for computer viruses
Viruses—programs that damage files or erase disks—can be
introduced into your computer from a floppy disk, from a shared
disk on a network, or from an electronic bulletin board service.
Programs that detect and eliminate viruses are available from user
groups, bulletin boards, and dealers.
You should check for viruses frequently if you exchange disks
or data with other users. Some programs check for viruses
automatically.
m Check all disks—even those in new, unopened commercial
software packages—for viruses before using them or copying
anything from them to your hard disk.
m Check your hard disk regularly with a virus-detection program
and correct any problems the program finds.
m Since new viruses appear regularly, make sure you have the
latest version of your virus-detection software.
