High Risk Virus Spreading Rapidly

A new variant of the dangerous Bugbear virus is on the loose and has begun spreading rapidly. Bugbear.B is quite similar to the original virus except that the new version contains a keystroke logger and is capable of changing its appearance to evade detection.

As of about 4 p.m. EDT Thursday, MessageLabs had stopped more than 55,000 copies of the new strain of Bugbear, which is infecting about one in every 200 pieces of e-mail, according to the company's statistics.

The fast-moving Bugbear.B virus continued to spread Thursday afternoon, but most of the damage has been done outside the United States. England and Italy have been the hardest hit so far, according to statistics compiled by New York-based e-mail security provider MessageLabs Inc.
