Internet experts are warning of a new multitude of extremely dangerous computer viruses that have recently been causing devastation and could potentially cripple entire global computer systems. These viruses can replicate thousands of copies within hours and are capable of extirpating security software that, in turn, enables hackers to appropriate control of the machines. Criminal gangs can then establish bank accounts using stolen identities, sabotage a companys computer system and extort money for its restoration, and sell computers that have been interfered with on the black market. Computer users are often advised to refrain from operating suspicious programs attached to emails and to continually update their security software.
