"Foad Fadaghi, senior industry analyst at Frost & Sullivan Australia, said that most viruses are designed to harvest e-mail addresses and other personal information from an infected system. He warned that because desktop search tools such as those recently announced by Google, Microsoft and Yahoo can index and categorize that information, virus writers are likely to start exploiting the technology."
