I'm currently using Bitdefender Internet Security which was automatically updated to the 2019 version. The first issue I was greeted with was the new "Always On" AutoPilot mode, which I'm really not a fan of, but I guess I can live with it.
My biggest issue right now is wiith USB drives. The activity light is constantly flashing on all of my drives, whether in use or not. At first I thought maybe the devices were still being scanned, but after 24 hours, the drives are still showing activity. Even after formatting one of the drives, the activity light continues to flicker like crazy.
On my other machine which is still on the 2018 version (for now) doesn't have this issue. After scanning the drive the activity light stops until I access or write something to the drive.
I hope this isn't considered normal behavior for the new version, since I don't think it's good for the drives in the long term. my main concern is that on my other machine I also have some USB External Hard Drives which only power down if left inactive. I don't want these drives to be running 24/7, or worse still, constantle being woken up after entering sleep mode.
I should also mention, the constant activity on the USB drives is shown in Windows Resource Monitor, but there are no details on what's actually going causing the constant activity.
Any advice or suggestions would be greatly appreciated. My last resort would be to uninstall and reinstall. Failing that, I have no choice but to find another product which I really don't want to do.
