Despite the worm's seemingly helpful nature, some security experts are not amused.

"Presumably this was a well-intentioned action, but where does it all end?" wondered Mike Fergamo, a systems administrator. "Next week will we have an antiworm for the antiworm's antiworm?"

But some users welcomed the worm.

"My computer hasn't been right since it was infected last week," said Nadine Lovell, a Manhattan textile designer. "This afternoon it's working perfectly again."
