US: Aggressive computer virus spreads

A new computer virus that offers hackers full control of infected PCs, giving them access to critical information such as passwords and credit-card numbers, was spreading on the Internet tonight.

The virus, dubbed BugBear.B by virus experts, follows two other quickly spreading e-mail viruses seen in recent weeks – Sobig.B and Sobig.C – but far exceeds them in its ability to do harm and in the aggressiveness of its spread.
