Item 3.01(a)        Notice of Failure to Satisfy a Continued Listing Rule or Standard

On August 24, 2011, CyberDefender Corporation (the “Company”) received a letter from the Listings Qualifications Department of The Nasdaq Stock Market (“Nasdaq”) stating that, because the Company’s Market Value of Listed Securities (“MVLS”) (as that term is defined in Nasdaq’s Listing Rules) was less than $50,000,000 during the period from July 13, 2011 to August 23, 2011, the Company no longer meets the requirement of Listing Rule 5450(b)(2)(A).  The Nasdaq letter also states that the Company does not meet the total assets and total revenue standard of Listing Rule 5450(b)(3)(A), and a deficiency therefore exists with regard to the Listing Rules.

The Nasdaq letter states that, pursuant to the Listing Rules, the Company has a 180 day compliance period, which expires on February 21, 2012, during which it must comply with the Listing Rules.  If during the compliance period the Company’s MVLS closes at $50,000,000 or more for a minimum of ten consecutive business days, Nasdaq will provide the Company written confirmation of compliance and the matter will be closed.   In the event the Company does not regain compliance prior to the expiration of the compliance period, the Company will receive written notification from Nasdaq that the Company’s securities are subject to delisting.  The Nasdaq letter also states that, alternatively, the Company might consider applying for a transfer to the Nasdaq Capital Market provided the Company satisfies the requirements for continued listing on that market.

In the event the Company does not regain compliance prior to the expiration of the compliance period, the Company will receive written notification from Nasdaq that the Company’s securities are subject to delisting.  The Nasdaq letter also states that, alternatively, the Company might consider applying for a transfer to the Nasdaq Capital Market provided the Company satisfies the requirements for continued listing on that market.

On August 30, 2011, the Company received a second letter from Nasdaq stating that, because the Company has not maintained a minimum bid price of $1 per share during the period from July 19, 2011 to August 29, 2011, the Company no longer meets the requirement of Listing Rule 5450(a).

The second Nasdaq letter states that, pursuant to the Listing Rules, the Company has a 180 day compliance period, which expires on February 27, 2012, during which it must comply with the Listing Rules.  If during the compliance period the closing bid price of the Company’s common stock is at least $1 for a minimum of ten consecutive business days, Nasdaq will provide the Company written confirmation of compliance and the matter will be closed.  The second Nasdaq letter also states that, if the Company chooses to implement a reverse stock split, it must complete the reverse split no later than ten business days prior to the expiration of the compliance period on February 27, 2012.  Finally, the second Nasdaq letter states that the Company may be eligible, pursuant to the Listing Rules, for additional time following the expiration of the compliance period.
