'Petya' computer virus spreads all the way across the world, but is gradually slowing down

The computer virus that spread rapidly across the world is still making its way to more companies and countries – but is gradually slowing down. The software doesn't appear to be vulnerable to the same "kill switch" that stopped the similar Wannacry virus just weeks ago, however, and so is likely to continue to travel around the world. The attack appeared to have started in Ukraine and then made its way across Europe, hitting companies including the world's biggest advertising company in Britain and Danish international Maersk. It then continued to spread, arriving in the US and then in Asia. The I.F.O. is fuelled by eight electric engines, which is able to push the flying object to an estimated top speed of about 120mph.
