With all of my installations (hw SG125, virtual from ISO and virtual from ovf template) Anti Virus service was stopped after first reboot and I have to manually started it. I still have problems with Av service (stopped after started) on virtual installation from ISO.
I have to reinstall the problematic installation in vmware and use ovf import procedure. Now AV service is working, but I have to start manual update and after that the AV service was started. I can confirm that restore from backup is working, for now I just noticed that admin password was not restored.
