Microsoft Anti-Virus for Windows (MWAV) may report either of the following
• Insufficient DOS Memory
• Insufficient MS-DOS Memory
• Not Enough Memory
This problem can occur in both standard and 386 enhanced modes.
This problem can be caused by incompatible terminate-and-stay-resident
(TSR) programs or by third-party video drivers.
To work around this problem, do the following:
• Use the Interactive Startup feature to start your computer withoutloading unnecessary TSRs. For more information on Interactive Startup,
see the "Configuring Your System" chapter in the "User's Guide."
• Run Microsoft Windows Anti-Virus right after you start Microsoft
Windows (that is, before you run other applications).
• Try using a video driver provided with Microsoft Windows 3.1 or 3.11,
such as the standard VGA video driver.
When Microsoft Anti-Virus requests this memory, the program has to
share the 640-kilobyte (K) conventional MS-DOS memory with the Windows
kernel and any other terminate-and-stay-resident (TSR) programs loaded
prior to running Windows. Windows drivers and other Windows-based
applications also use conventional memory. These Windows-based
applications, when closed, should free this conventional memory
however, some do not.
