As the world waited for one computer virus to strike on Friday, another wriggled its way into the Russian stock exchange and knocked it offline. Computer experts had warned that 3 February could bring gloom for many as a computer virus called Nyxem was scheduled to start deleting files on machines it had infected.

The virus was released several weeks ago and has spread by forwarding itself to email addresses found on the computers it infects.
