F-Secure to start repurchase of own shares

F-Secure's Board of Directors has in its meeting on August 26, 2009 decided to
start repurchase of its own shares based on the authorization of the Annual
General Meeting of March 26, 2009. The maximum number of shares to be
repurchased is 1.500.000 shares, representing 1% of all the shares issued by
the Company. F-Secure currently holds 990.932 own shares. 

The shares are purchased through public trading on the Nasdaq OMX Helsinki in
accordance with its rules and at market price. 

The own shares will be purchased to be used for making acquisitions or
implementing other arrangements related to the Company's business, to improve
the Company's financial structure, to be used as part of the incentive
compensation plan or for the purpose of otherwise assigning or cancelling the
shares. 

The repurchase of own shares will commence after September 3, at the earliest.
