Vista Less Secure Than XP?

Natalya Kaspersky, the company's chief executive, said that without UAC, Vista will be less secure than Windows XP SP2. ''There's a question mark if Vista security has improved, or has really dropped down,'' she said to our sister site ZDNet UK at the CeBIT show in Hanover last week. Kaspersky provides one of the scanning engines in ForeFront, Microsoft's business security product.
