Actually, says Antony Holdsworth, technical consultant for Kaspersky Labs' United Kingdom office, his company recently started posting a new signature file on its servers every three hours.

"We're seeing about 300 new viruses a week," Holdsworth explains."There are always new anti-virus signatures to post," even with updates scheduled eight times a day, he adds.

Kaspersky schedules new signature files the most often — and earned the fastest average response times in AV-Test's real-time trials, shown above — because the company has a large number of people around the world analyzing viruses and developing cures, Holdsworth says.
