I completely dump ZA. Used to have ZA with Kaspersky combo but after upgrading to 6.5, my pc auto restart every 3 minutes. I tot theres something wrong with my hardware, took my pc for checkup and found nothing wrong. Then I notice theres a pop up (0.5 second) before my pc auto restart. Uninstall ZA and everything is fine. So no more ZA for me. Stick with KIS for now.
