The Group total costs were 59.5 (51.6m), 15% higher than in 2007. The Q3 cost   
level was seasonally low due to the vacation period. The Group has also         
capitalized some of its development expenses of approximately 0.2m according to 
accounting rules.                                                               

The financial results for the first nine months of 2008 were in line with the   
guidance given in July (revenues 81.3m-83.3m, costs below 60.2m).               

The geographical breakdown of the revenues was as follows: Nordic Countries 39% 
(39%), Rest of Europe 43% (43%), North America 9% (9%) and Rest of the World 9% 
(9%). Anti-virus and intrusion prevention products for the Internet represented 
close to 100% of the total revenues.                                            

ISP channel in Q3                                                               

The solid development in the Group's Internet Service Provider (ISP) business   
continued as anticipated. A total of five new ISP partnerships were signed      
during Q3. The total number of ISP partners at the end of Q3 was 178 operating  
in 42 countries.

(ISP) partners were 12.3m (9.4m), representing 43% of the total revenues (39%)  
and a growth of 31% compared to 2007. The revenue growth compared to the        
previous quarter was 6%.                                                        

New service provider partnerships announced in Q3 comprise Tele2 (Netherlands)  
and UnityMedia (Germany). Additionally, TDC (Denmark) has signed partnership    
with F-Secure, covering the protection of both PC and mobile subscribers.       

At the end of Q2, F-Secure successfully launched a new service offering for its 
ISP partners, the Online back-up services for broadband users. The new service  
offering has been well received among customers and the first contracts are     
already signed in Italy (WIND-Infostrada) and Germany (UnityMedia). This new    
service complements F-Secure's existing portfolio of data security services, and
further strengthens the company's strategy of offering value added services     
through Internet Service Providers.                                             

Other channels in Q3                                                            

The traditional sales channels, including Value Added Resellers, IT Service     
Providers, Managed Security Service Providers, e-Store and Retail channels      
continued to perform solidly. The channel revitalization program for delivering 
solid growth in sales through the traditional channels has progressed well.     

Revenues were 16.3m (14.9m). This represented 57% of the Group's total revenues 
(61%), growth of 10% from the previous year.                                    

Mobile security in Q3                                                           

Close co-operation with Nokia and Sony Ericsson together with operator          
partnerships, such as Orange UK, Orange Switzerland, T-Mobile Germany, T-Mobile 
UK, Swisscom, CSL Hong Kong, TeliaSonera and Elisa, is the prime vehicle to make
mobile security applications available to a large number of end users.          

During Q3, F-Secure signed new contracts with KPN in the Netherlands and Netia  
in Poland to deliver mobile security to their subscribers. Additionally, TDC    
(Denmark) signed a partnership with F-Secure, covering the protection of both PC
and mobile subscribers.                                                         

The Group signed the Global Frame Agreement with Vodafone in Q2, on the delivery
of mobile security for major handset platforms to Vodafone customers. During Q3 
Vodafone UK was the first Vodafone operating company to launch the service.     

Mobile security revenues were at the level of approximately 3% of the Group's   
total revenues in Q3. These revenues are included in the above-mentioned channel
revenues and the percentage figure is shown as an indicator only.               

Products & Services in Q3                                                       

In September, F-Secure launched a new Internet Security 2009 for the protection 
against new online threats. By using the F-Secure DeepGuard™ 2.0 technology it  
recognizes both safe and malicious software instantaneously using a real-time   
protection network. In addition to providing quality of protection, F-Secure    
Internet Security 2009 also includes performance improvements, for example easy 
automatic installation and faster boot-up, scanning and disinfection times.     

Internet Security 2009 has gained excellent results in tests (e.g. AV-Test      
GmbH., an independent testing organization specializing in security solutions). 
Internet Security 2009 belongs to a product family called Wellbeing 2009, which 
includes F-Secure Internet Security 2009, F-Secure Anti-Virus 2009, F-Secure    
Home Server Security 2009 and F-Secure Health Check.                            
Competitive situation                                                           

There were no significant changes in the competitive landscape during the       
quarter. However, compared to the situation one year ago, competition in the    
traditional corporate channel has become tougher resulting in negative price    
development in some countries. The Group's competitive position in the ISP      
channel has remained strong.                                                    

Personnel and Organization                                                      

The Group's personnel totaled 710 at the end of September (543). The Group has  
pursued its strategy to further reinforce its global sales and marketing        
organization.

President, Strategy), Mr. Taneli Virtanen (Chief Financial Officer) and Mr.     
Seppo Ruotsalainen (Senior Vice President, Sales and Geographical Operations).  

Financing

The change in the USD-EUR exchange has had some positive effect on revenues and 
results.

The Group's capital expenditure during the first nine months of 2008 was 2.4m   
(1.6m). This consisted mainly of IT hardware, software and capitalization of    
some development expenses.

Risks and Uncertainties                                                         

The Group has not seen any material changes to the risks and uncertainties      
during the reporting period. The current situation in the financial markets has 
not had an impact on F-Secure's businesses.                                     

The Group's risks and uncertainties are related to, among other things, the     
competitiveness of the Group's product portfolio, competitive dynamics in the   
industry, impact of changes in technology, timely and successful                
commercialization of complex technologies as new products and solutions, the    
ability to protect own intellectual property (IPR) in the Group's solutions as  
well as the use of third party technologies on reasonable commercial terms,     
subcontracting relationships, regional development in new growth markets,       
sustainability of partner relationships, service quality level requirements and 
the overall development of value added security solutions in the Service        
Provider and mobile operator market.                                            
                                                                                
Capital management and invitation for an extraordinary general meeting          

F-Secure has in its review for 2007 stated that the objective of the Group's    
capital management is to aim at an efficient capital structure that ensures the 
functioning of business operations and promotes the increase of shareholder     
value. The Annual General Meeting 2007 decided to decrease the share premium    
fund and transfer the decreased amount to distributable equity fund.            

In October, the Board made a proposal regarding the returning of equity to      
shareholders of EUR 0.23 per share and on the consequent changes to subscription
price of the Group's option programs. The Board proposes to the general meeting 
that the returned amount would be a total of EUR 35,719,370.76 for a total of   
155,301,612 shares (EUR 0.23 per share). The Board has called an extraordinary  
general meeting of shareholders on October 28, 2008. The details concerning the 
extraordinary general meeting are published in a stock exchange release on      
October 8, 2008.                                                                

Events after Q3                                                                 

In October, F-Secure divested some of its network control technology. The sale  
will improve the operating profit for Q4 by approximately 0.8m.                 

Changes in the Group's financial position after Q3                              

No other major changes regarding the Group's business or financial position have
materialized after the end of September 30, 2008.                               

Future Outlook                                                                  

The Group's first priority is to drive strong growth. The core growth driver is 
the ISP channel. The growth is driven by a combination of security services and 
new value added services (such as online backup). The Group continues to invest 
in new sales and marketing activities to build scalability for future growth    
especially for the service providers and in the mobile segment. The Group       
continues to pursue innovations in the IT security related technologies as well 
as in new services related to the online wellbeing of Internet users.           

The annual growth rate in the ISP business is expected to be between 34% and    
37%, with accelerated growth at the end of the year. The revenue growth estimate
in the previous interim report was between 35% and 40% annual growth. During    
second half of 2008 the online backup service launch with ISPs has taken longer 
than anticipated.                                                               

In the mobile security business revenues are expected to grow steadily. However,
it is expected to remain a small part of the Group's revenues during 2008.      

The fourth quarter 2008 revenues are estimated to be between 29.5m and 31.5m.   
Fixed costs are estimated to be below 22m. The revenue estimates are based on   
the sales pipeline at the time of publishing, existing subscriptions and support
contracts and a EUR/USD exchange rate of 1.40. The current uncertainty in the   
global economy is not anticipated to impact F-Secure's businesses during Q4.    

The Management expects the full year revenue to be between 112 and 114 million  
and full year EBIT between 20 and 23%. The guidance given for full year 2008 at 
the beginning of the full year was the following: revenues to be between 110 and
120 million and EBIT between 19 and 23% of revenues.                            

In the 2-4-year horizon the Group aims to continue to exceed the average market 
growth rates in revenues and seeks an EBIT level around 25%.
