Software Installation and Configuration
When you obtain software, check it for viruses with virus-scanning software before installing it on your computer's hard drive. Viruses, which are
pieces of code that can replicate themselves, can quickly use all available system memory, damage or destroy data stored on the hard drive, and
permanently affect the performance of the programs they infect. Several commercial virus-scanning programs are available for purchase, and most
bulletin board services (BBSs) archive freely distributed virus-scanning programs that you can download with a modem.
Before you install a program, read its documentation to learn how the program works, what hardware it requires, and what its defaults are. A
program usually includes installation instructions in its accompanying documentation and a software installation routine on its program diskette(s)
or CD(s).
The software installation routine assists you in transferring the appropriate program files to your computer's hard drive. Installation instructions may
provide details about how to configure your operating system to successfully run the program. Always read the installation instructions before
running a program's installation routine. You may be instructed to modify some operating system start-up files, such as
config.sys and
autoexec.bat , or the installation routine may modify start-up files automatically.
When you run the installation routine, be prepared to respond to prompts for information about how your computer's operating system is
configured, what type of computer you have, and what peripherals are connected to your computer.
