The Department has conducted a series of surveys of business to gauge the impact of IT security breaches and the response to security challenges such as the increase in malicious software. There is no doubt that such software is a serious threat to business and domestic users, and practical advice on protecting systems against it features in our work with GetSafeOnLine
http://www.getsafeonline.org/
aimed at informing the public and smaller businesses; our work with business through the Digital Systems Knowledge Transfer Network; and our work with the management of the Critical National Infrastructure. The pursuit of those who develop and use such software is a matter for the law enforcement authorities.
