FormShared.A is a worm that spreads a component of itself, which belongs to the Trojan Spyforms.S, through peer-to-peer (P2P) file sharing programs.

In order to do so, FormShared.A has its own P2P client. Then, it creates a subfolder called SHARED in the Windows directory with certain files so that other users that other users of this type of networks voluntarily download SpyForms.A.

FormShared.A is difficult to recognize, as it does not display any messages or warnings that indicate it has reached the computer.
