This is the Autoexec.bat (regedit) from Cai Tuzi's backup. I can understand that it uses Attrib to change the attributes of my original registry, and then uses copy to restore it. What I don't understand is why it adds this at the top: @ECHO OFF In the .bat files I made, I put in the full path of the antivirus software, and when I put them on the boot disk they also start the antivirus, but there is no @ECHO OFF.


@ECHO OFF
C:\WINDOWS\COMMAND\ATTRIB -R -H -S C:\WINDOWS\SYSTEM.DAT
COPY C:\WINDOWS\MAGICSET\SYSTEM.DA C:\WINDOWS\SYSTEM.DAT /Y
C:\WINDOWS\COMMAND\ATTRIB -R -H -S C:\WINDOWS\SYSTEM.INI
COPY C:\WINDOWS\MAGICSET\SYSTEM.IN C:\WINDOWS\SYSTEM.INI /Y
C:\WINDOWS\COMMAND\ATTRIB -R -H -S C:\WINDOWS\USER.DAT
COPY C:\WINDOWS\MAGICSET\USER.DA C:\WINDOWS\USER.DAT /Y
C:\WINDOWS\COMMAND\ATTRIB -R -H -S C:\WINDOWS\WIN.INI
COPY C:\WINDOWS\MAGICSET\WIN.IN C:\WINDOWS\WIN.INI /Y
C:\WINDOWS\COMMAND\ATTRIB -R -H -S C:\WINDOWS\CLASSES.DAT
COPY C:\WINDOWS\MAGICSET\CLASSES.DA C:\WINDOWS\CLASSES.DAT /Y
C:\WINDOWS\COMMAND\ATTRIB -R -H -S C:\WINDOWS\CONTROL.INI
COPY C:\WINDOWS\MAGICSET\CONTROL.IN C:\WINDOWS\CONTROL.INI /Y
C:\WINDOWS\COMMAND\ATTRIB -R -H -S C:\WINDOWS\WIN.COM
COPY C:\WINDOWS\MAGICSET\WIN.CO C:\WINDOWS\WIN.COM /Y

Ah~ this has no real significance, it just turns off the screen display...

Oh, many thanks, expert!
