The script solution was targeted to those who choose for what ever reason to use cron rather than running freshclam as daemon. I used to mirror files that were updated at odd times and I can tell you that lockstep is a real problem. I update my signatures twice daily, but I don't have any Windows equipment to worry about. My problem with freshclam as a daemon was the need to add yet another daemon watcher to keep it going, and the presence of a process that 99% of the time did nothing. And that the wake-up time is based on the startup time and not clock time. dp _______________________________________________ Help us build a comprehensive ClamAV guide: visit http://wiki.clamav.net http://www.clamav.net/support/ml
