m Check for multiple System Folders on your startup disk, using the Find File
command. Throw away extra System Folders (but do not throw away any
System Folders from your RAM Disk Backup folder). The System Folder

Eliminate any viruses the program finds.
m If a problem recurs when you are using a particular program, try
the following:
m Consult the documentation that came with the program to make sure you
are using it correctly.
m Check for multiple copies of the program on your hard disk. Use the Get
Info command to check the programs’ version numbers. Keep one copy
of the latest version and throw away all other copies.
m Reinstall the program from a known good source (such as the original
program disks or the CD that came with your computer).
m Increase the program’s memory. Quit the program, select its icon, choose
Get Info from the File menu, and type a larger number in the Preferred
Size box.
