Anti-virus is a program that can identify, capture and destroy an application or program that is infected as a virus. Antivirus application programs are divided into 3:

1. Fix
A program that can detect and destroy only one virus. Must be run first then the program will find and remove certain viruses. For example: Fixnimda (from NAV), FixCodered (from NAV), etc.

2. Antidote

A program that can catch, detect several types of viruses and remove them. Just like the fix program, it must be run first and then it will look for infected files or certain virus files For example: Wedash Anti Dot 2004.

3. Anti Virus
A program that can catch, detect and remove many types of viruses. It can automatically capture infected files and delete them. For example: Norton Antivirus, McAfee Antivirus, SmaDav etc

The Concept of Making Antivirus

To make an antivirus, position yourself temporarily not as a programmer first but as a doctor. how come it's a doctor, does it have anything to do with it?

The first step we have to understand from a disease is the impact or consequences that have been produced. For example, people who are sick with the flu will automatically give water or flu medicine instead of giving cough medicine .. understand what it means... to try whether the antivirus works or not. No, we definitely need volunteers. You will automatically ask for a volunteer to test the virus. But what if there are no volunteers? Like it or not, we have to spread the virus secretly by using email or FD

let's start making this simple AV....

Let's make a script first to autorun on our Flashdisk....just type it in notepad

| |

|[AutoRun] |

|open=namaantivirus.exe |

|shellexecute=antivirusname.exe |

|shellScan_Virus)_!!!command=antivirusname.exe |

|shell=Scan_Virus)_!!! |

| |

|---------------------------------------------------------------------------------------|

try copying the script in notepad first....we'll save it with the name "autorun.inf" (not using quotes) on our flash drive, now we just need to copy it antivirus that we want to enter into the flash ..!!! (remember....if you copy the autorun n' antivirus file, it's not in the folder..)

if you want to scan for viruses, just double click on our flash drive!! if we right click the flash drive there will be an additional word above the word AUTOPLAY.

if you want to change it, we just need to change the words in the script...!

|-----------------------------------------------------------------------|

| shellclean-firstcommand=antivirusname.exe |

| shell=clean |

|-----------------------------------------------------------------------|

Done.
