The world overview of the effects of the Datacrime virus on Friday night from David Frost of Price Waterhouse was that aside from the reported cases in the UK, the most significant outbreak was probably within Swiss government networks where about 35,000 personal computers went down, while a couple of companies were affected in Holland: in the US, where the virus is known as Columbus Day most firms had a vaccine program, but one advertising company had been hit and there was a near miss at a large software producer where controls stopped the virus and violated it before it could stop production of compilers.
