For the first quarter of 2008 total revenues were 26.6m (23.1m), representing

Deferred revenues were 33.7m at the end of the quarter (31.9m at the end of     
4Q2007).                                                                        

The total costs were 19.5m (17.4m), representing 12% growth. The Group          
capitalizes some of its development expenses according to the accounting rules. 
This had no material impact on the cost level.                                  

The results were in line with the given guidance (revenues 26m-28m, costs not   
exceeding 20m).                                                                 

The geographical breakdown of the business was as follows: Nordic Countries 40% 
(39%), Rest of Europe 43% (44%), North America 8% (8%) and Rest of the World 9% 
(9%). Anti-virus and intrusion prevention represented close to 100% of the total
revenues.                                                                       

ISP channel                                                                     

Strong development in the Service Provider business continued and a total of 6  
new ISP partnerships were signed in Q1. Two partner operators merged into       
existing partners without loss of business for the Group. The total number of   
ISP partners was 169 operating in 38 countries at the end of the quarter.       

New service provider partnerships signed in Q1 include Cabovisao (Portugal),    
Comstar-Direct (Russia), and Ziggo (The Netherlands).                           

In the first quarter of 2008, revenues through the Internet Service Provider    
(ISP) partners were 10.9m (7.8m), representing 41% of the total revenues (34%)  
and a growth of 41% from the previous year. The quarter-over-quarter revenue    
growth was 8% (7% in 4Q2007).                                                   

The total number of the Group's ISP partners is significantly larger than with  
any other security service vendor. At the end of 2007 the Group's ISP partners  
held approximately 37% (34%) market share of total high-speed consumer          
connections in Europe, approximately 10% (10%) in North America and             
approximately 9% (n/a%) in APAC (Source: Dataxis and F-Secure).                 

Other channels                                                                  

The traditional sales channels, including Value Added Resellers, IT Service     
Providers, Managed Security Service Providers, e-Store and Retail channels grew 
by 2% from the previous year. Revenues were 15.7m (15.4m) and represented 59% of
the total revenues (66%).                                                       

F-Secure Protection Service for Businesses, which was launched during 4Q 2007,  
has continued to gain significant interest among Value Added Reseller partners  
and the business customers.                                                     

Mobile security                                                                 

Mobile security revenues were at the level of approximately 3% of the Group's   
total revenues in Q1. These revenues are included in the above-mentioned channel
revenues and the percentage figure is shown as an indicator only.               

In the first quarter F-Secure signed a partnership with Toshiba Information     
Systems (UK) Mobile Communications Division to provide F-Secure Mobile          
Anti-Virus for Toshiba's Windows Mobile smart devices throughout Europe. The    
Group also launched a partnership with CSL, Hong Kong's largest mobile operator,
to provide an integrated mobile security service.                               

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, TeliaSonera and Elisa, is the prime vehicle to make mobile        
security applications available to a large number of end users. Co-operation    
initiatives with other major mobile operators and handset manufacturers are also
progressing well.                                                               

Products & Services                                                             
                                                                                
Key product announcements in Q1 include F-Secure Health Check for   Service     
Providers, Protection Service for Business, and a new version of F-Secure       
Anti-Virus for Windows Servers.                                                 

After the reporting period the Group announced F-Secure Mobile Security for     
Windows Mobile, combining real time anti-virus and anti-spyware with a firewall 
for this mobile platform.                                                       

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.                                                    

Customer satisfaction                                                           

F-Secure updated its annual customer satisfaction survey at the end of 2007. The
overall satisfaction was healthy at a  level of 4.1 on a scale from 1 to 5.     

Personnel and Organization                                                      

The Group's personnel numbered 602 at the end of the Q1 (514).                  

The Group has been successful in pursuing its strategy to reinforce above all   
its global sales and marketing organization.                                    

The current Executive Team consists of the following persons: Mr. Ari Alakiuttu 
(Vice President, Human Resources), Mr. Kimmo Alkio (President and CEO), Mr.     
Trond Neergaard (Vice President, ISP Business), Mr. Pirkka Palomäki, (Chief     
Technology Officer), Mr. Antti Reijonen, (Vice President, Strategy), Mr. Taneli

The Group's financial position remained strong. The Group's equity ratio on     
March 31, 2008, was 71% (79%). The equity ratio would have been 81% if the      
dividends had been  paid  in March. Financial income for the first quarter was  
0.3m (0.2m).                                                                    

During the first quarter cash flow was 6.1m positive (8m positive before        
dividend paid in March 2007).                                                   

The market value of the liquid assets of the Group on March 31, 2008 was 90.3m  
(72.4m).                                                                        

A dividend of EUR 0.07 per share was paid after the reporting period, on April  
8, 2008, representing a total of 10.9m for all outstanding shares.              

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

Risks and Uncertainties in the Near Future                                      

The Group has not seen any material changes to the risks and uncertainties      
during the reporting period.                                                    

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, the 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, database update 
process quality,  and the overall development of value added security solutions 
in the Service Provider and mobile operator market.                             

Disputes                                                                        

Helsinki Court of Appeal announced its decision on the dispute between F-Secure 
Corporation and SRV Viitoset Oy. F-Secure was sentenced to pay EUR 793 230,53   
and the costs of the trial plus interest to SRV Viitoset Oy. F-Secure considers 
applying for leave to appeal for Supreme Court. F-Secure has already accrued    
payments based on the verdict by Helsinki District Court. The financial impact  
pursuant to this claim is periodized for the duration of the rental period      
starting from September 2005 until the end of 2010.                             

Based on an agreement by and between the parties, Diagnostic Systems Corporation
dismissed their patent infringement claim of December, 2006.                    

Future Outlook                                                                  

The Group's first priority is to drive strong growth. The core growth element is
the ISP channel.                                                                

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 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 approximately 40%  
in 2008.                                                                        

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.      

Management expects full year 2008 revenues to be between 110 and 120 million and
full year 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%.                    
                                                                                
The second quarter 2008 revenues are estimated to be between 26.5m and 28.5m.   
Fixed costs are estimated to be below 21m in Q2.                                

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     
1.55.
