Re: CyberDefender Corporation Form S-1 filed on September 8, 2009 as amended on October 19, 2009 and October 30, 2009 File No. 333-161790

Dear Ms. Jacobs:

CyberDefender Corporation (the “Company”) hereby requests that the Securities and Exchange Commission take appropriate action to make the above-captioned registration statement be ordered effective at 2:00 p.m., Eastern time, on November 5, 2009 or as soon as practicable thereafter.

In requesting acceleration, the Company acknowledges that:

(1)           should the Commission or the staff, acting pursuant to delegated authority, declare the filing effective, it does not foreclose the Commission from taking any action with respect to the filing;

(2)           the action of the Commission or the staff, acting pursuant to delegated authority in declaring the filing effective does not relieve the Company from its full responsibility for the adequacy and accuracy of the disclosure in the filing; and

(3)           the Company may not assert the declaration of effectiveness as a defense in any proceeding initiated by the Commission or any person under the federal securities laws of the United States.
