The use of malicious software to attack individuals, business and government, increased by 250% in 2008, it said.

Online bank fraud was worth more than £52m last year, and online fraud and other crime cost small businesses on average £800 each a year, it said.
The government created the Serious Organised Crime Agency (Soca) to set up off-shore alliances to tackle foreign crime gangs.
Last year it set up the Police Central E-Crime Unit to coordinate the national police response to e-crime, and last month it set out a new cyber security strategy that will use "white hat" hacker teams to attack cybercriminals.
