SoBig.F continues to proliferate online party because of the security measures taken to remove it. When the 20 or so computers that SoBig.F was targeting were taken offline the virus continued to look for them and continues to do so today. SoBig.F will continue to spread and look for these computers until it finds them -- which it won't because they have been disconnected. SoBig.F was supposed to peak on August 19th, so there could also be machines online with incorrect clocks and computers without current anti-virus software. Despite its persistance SoBig.F will eventually fade away.
