That's one of the big reasons why it isn't possible to write a signature-based antivirus these days. You're caught in the nutcracker of 1) need to update frequently and 2) need to test adequately. I don't see how it's possible to do daily updates, let along hourly. Even weekly updates sounds too difficult. On Fri, 21 Dec 2007, Larry Seltzer wrote:
I remember years ago writing about the speed of updates necessary now for a/v vendors, and how kaspersky talked about how they do it hourly. It basically makes it impossible to do meaningful tests.

As a result the core Windows component was quarantined or worse. Kaspersky released a revised update alongside advice on how to recover legitimate system and application files from quarantine (the default setting) within two hours. But that's not much consolation for users that had set their software to auto-delete infected files, who found themselves with hosed systems. Among those affected was Reg reader Carl. "A false positive caused the deletion of explorer.exe.," he reports. "It would have only caused problems for companies performing their network scan during the hours that the dodgy update was present - which included me, unfortunately.
