Some time ago an intensive care unit in Glasgow found that its normally well ordered computer network was becoming erratic: data were being corrupted and files were being lost. Recently a general practitioner who used an IBM compatible computer for his repeat prescriptions discovered that important files were being corrupted. In both cases a computer virus was at work. Eventually the viruses were identified and exterminated, but not quickly and not without the loss of data.
