Brief Description 

    

Netsky.Q 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.Q attempts to launch DoS (Denial of Service) attacks against several web pages, between April 8 and 11, inclusive.

Netsky.Q spreads via email in a message with variable characteristics. It is automatically activated when the email message is viewed through Outlook's Preview Pane. It does this by exploiting a vulnerability in Internet Explorer, which allows email attachments to be automatically run. This vulnerability exploit is known as Exploit/iFrame.

In addition, when the system date is March 30, 2004, between 5:00 a.m. and 10:59 a.m., Netsky.Q emits a sound that consists of random tones through the internal speaker.

Netsky.Q is easy to recognize, as it emits a sound that consists of random tones through the internal speaker when the system date is March 30, 2004, between 5:00 a.m. and 10:59 a.m.
