Why should I be worried about crimeware? What are the risks of having crimeware in my computer or company?

The effects of these types of threats and attacks include:

    The risk of theft of confidential corporate or financial information and the invasion of privacy. It is an evolution of industrial espionage, without the need to have ‘moles' on the inside stealing corporate information. The consequence of this type of action can stretch from financial loss to even bankruptcy or other potentially ruinous consequences for companies.
    Legal problems, given that if an attacker were to take control of one or more computers and launch, say, a denial of service attack, the IP address of the attacker would be that of the user, who would have no knowledge of this action.
    The annoyance of unwanted advertising and other similar action.

Productivity losses due to system slowdowns, operating system errors, general computer problems, etc. caused by the threats themselves which could be camouflaged
