SYMPTOMS
Microsoft Anti-Virus for Windows (MWAV) may report either of the following error messages:


 * Insufficient DOS Memory
 * Insufficient MS-DOS Memory
 * Not Enough Memory

This problem can occur in both standard and 386 enhanced modes.



CAUSE
This problem can be caused by incompatible terminate-and-stay-resident (TSR) programs or by third-party video drivers.



WORKAROUND
To work around this problem, do the following:


 * 1) Use the Interactive Startup feature to start your computer withoutloading unnecessary TSRs. For more information on Interactive Startup, see the &quot;Configuring Your System&quot; chapter in the &quot;User's Guide.&quot;
 * 2) Run Microsoft Windows Anti-Virus right after you start Microsoft Windows (that is, before you run other applications).
 * 3) Try using a video driver provided with Microsoft Windows 3.1 or 3.11, such as the standard VGA video driver.



MORE INFORMATION
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.
