Malware writers appear to be much further along in developing malware for Vista than the security industry is in making products to protect the new operating system. Speaking exclusively to IT PRO, Tim Eades, senior vice-president of sales at security company Sana Security said that 38 per cent of malware is already Vista-compatible. “Malware writers have gone through the WHQL (Windows Hardware Quality Labs) list to make sure that their code works on new machines,” he said. He said that very few security vendors outside of anti-virus have products ready for the operating system.
