Brief Description 

    

Netsky.P is a worm that deletes the entries that belong to several worms, including Mydoom.A, Mydoom.B, Mimail.T and several variants of Bagle.

Netsky.P spreads via e-mail in a message with variable characteristics, and through peer-to-peer (P2P) file sharing programs.

Netsky.P is automatically activated when the e-mail message is viewed through Outlook's Preview Pane. It does this by exploiting a vulnerability in Internet Explorer, which allows e-mail attachments to be automatically run. This vulnerability exploit is known as Exploit/iFrame.

Visible Symptoms 

    

Netsky.P is difficult to recognize, as it does not show any messages or warnings that indicate it has reached the computer.
