what context is novastor running in and it should be using VSS for backing up. Which version of Novastor Backup? Pro/Server/Business Essentials?
Davis McCarnOwnerCommented:
VSS does need to be working for backing up open files; but, I think Audrey got herself infected.  That AT1 job in scheduled tasks is highly suspicious!
Thomas Zucker-ScharffSolution GuideCommented:
I really can't tell if that is an infection, but the occams razor solution would be that the permissions are not set correctly for the backup destination.
