Each time you start your computer, you receive an error message
stating that the system memory is being modified.
If you continually receive this error message, either you are
running VSAFE with the /2+ parameter (which checks for programs that
load as memory resident), or one of your programs is causing the error
because it does not use the MS-DOS Interrupt 21 application program
interface (API) function to load as memory resident.
To work around this problem, change the VSAFE /2+ parameter to /2-.
This disables the memory check for standard memory-resident programs.
If the warnings continue, note the program that causes the error
message. This program is not using the standard method to load as a
memory-resident program (Int 21h). Once you note which program is
causing the problem and verify that it is not infected with a virus,
load VSAFE after that program in the AUTOEXEC.BAT file.
