Fake virus detected(HARMLESS)

First we have to open notepad again
1.type this in or copy.
@echo off
echo WARNING VIRUS DETECTED
echo System check

pause


2.Save as a.bat
3.convert the a.bat to an exe file which lets you name it and change the icon.
4.to convert it you will need to goto www.f2ko.de and download bat_to_exe
5. put it on some ones computer and watch them freak out

RESULTS
Look at the screen shot below and this is what the person will see. where it says pause you have to press a key to see the writing below it.

Types of virus

Virus are classifed mainly on based on what they affect & how, size.


Based on what they effect.

1.Computer virus.
2.Mobile virus -Nowerdays many virus are written for mobile They spread through gprs/bluetooth.
3.Music player virus -There exsists only a handful of such virus.Theu spread when you add a song /video or dwnload some thing

Based on size

•Tiny virii - These are under 500 bytes. They are designed to be undetectable due to their small size. TINY is one such virus. They generally very simple because their code length is so limited.
•Large Virus- They are over 1,500 bytes. They are designed to be undetectable because they cover their tracks very well (all that code DOES have a use!). The best example of this is the Whale virus, which is perhaps the best 'stealth' virus in existence. •Other virus- These virus are easily detectable. Many virus are of this type.

Based on How they effect

All these many seam like compurt virus only but that is only partly true as your mobile too has an OS.

•Boot Sector Virus: This virus replaces or implants itself in the boot sector---an area of the hard drive (or any other disk) accessed when you first turn on your computer. This kind of virus can prevent you from being able to boot your hard disk.
•File Virus: This infects your applications. These then spread the virus by infecting other applications. You need to run or open these files.
•Macro Virus: These account for about 75 percent of viruses found in the wild. They are written using a simplified macro programming language, these viruses affect Microsoft Office applications, such as Word and Excel, and . A document infected with a macro virus generally modifies a pre-existing, commonly used command (such as Save) to trigger its payload upon execution of that command.
•Multipartite Virus: These infects both files and the boot sectorthat infect your system dozens of times before it's caught.
•Polymorphic Virus: A well written virus of this type is usually difficult for antivirus scanners to detect but these are usually not that well written. They changes code whenever it passes to another machine.
•Stealth Virus: These hides its presence by making an infected file not appear infected, but doesn't usually stand up to antivirus software.
