We support PCs at about 50 public libraries. The computers that are out for the public have Deep Freeze disk locking installed. We have a scheduled thaw period in the middle of the night so that maintenance tasks can occur and remain on the hard drive. Has anyone else come up with a solution for scheduling cloud-hosted AV Pro virus definition and program updates during the night only? I'd like the PCs to check for updates every night automatically during the thaw period. Thanks.
