The Setup Paragon Hard Disk Manager 11 Suite (version 10.0.17.13908 ) (paid license) Windows 7 Home Premium 64-bit, SP1 (version 6.1.7601 SP1 Build 7601) Intel Core i7 CPU, 6GB RAM, twin 1 TB disks. McAfee VirusScan Enterprise version 8.8, McAfee Agent version 126.96.36.1994 The Problem It looks as if there's a conflict between Paragon Backup Manager and McAfee Enterprise. Paragon differential backup will run in Windows Safe Mode, requiring about 2 hours to scan/backup 600 GB on a 1 TB disk, right after running a full disk snapshot (sector-wise backup of all volumes on the disk). Paragon differential backup stalls indefinitely when run in normal Windows operating mode. Turning off all programs that are run automatically at boot time, and all services that can be disabled does not change the result. Paragon complementary backup (file-wise increment based on sector-wise full backup) runs, but seem to take 48 hours or so, and it needs to run daily. We cannot test Windows in normal operating mode with McAfee disabled, because McAfee protects itself from any intervention except by the domain system administrator. The administrator is willing to work with us to add Paragon executables to the trusted programs list, but the Paragon documentation does not explain what services, exe files, device drivers, etc. it will run during a backup. (And of course it is silent on the common problem of getting Paragon to coexist with virus scanning software). Adding Launcher.exe and Plauncher_s.exe to the trusted programs list didn't solve the problem. Plea for Help I'd ask Paragon tech support, but their 90 day help period has expired. Therefore, has anyone here managed to get Paragon backup working with McAfee VirusScan Enterprise, and if so, how did you do it? Thanks for any insights into this vexing problem.
