drive, the operating system would manage the system as though it had 32 MB of physical RAM.

A self-starting program designed to inconvenience you. Virus programs have been known to corrupt the files stored on a hard drive or to replicate themselves
until a computer system or network runs out of memory. The most common way that virus programs move from one system to another is via "infected"
diskettes, from which they copy themselves to the hard drive. To guard against virus programs, you should do the following:
l Periodically run a virus-checking utility on your system's hard drive
