Victims sometimes receive dozens of e-mail messages, all contaminated with the virus.
The virus, which appeared in Hong Kong late Thursday afternoon, seemed to particularly hit, among other businesses, public relations firms and investment banks. Dow Jones and the Asian Wall Street Journal offices in Asia were among its victims. In Hong Kong, Nomura International Ltd. is receiving the e-mail virus, an analyst said. The virus has created a lot of damage in Nomura's London office, he said. Simon Flint, currency strategist at Bank of America in Singapore, said he has received e-mail messages warning him of the virus but hasn't received the actual virus.
