Looks like someone else with Bitdefender has begun having the exact same issue. Important, Windows 10 event view. - PROTECTION - Bitdefender Forum

Thanks for sharing. If this is the problem then I am again a happy man as it means both my laptop and SSD are fine. I was sure one was about to die :)

It certainly takes a bit of urgency out of it considering that the fix is in Bitdefender's hands now. I'd still like to see it resolved sooner rather than later though. Did uninstalling Bitdefender ever get rid of the warnings?

I disabled all bitdefender options, but didn't uninstall it. So I can't confirm that bitdefender is causing this or not. Meanwhile I have copied everything from my HDD to a backup USB device and will wait a little more to see what will come out on bitdefender side. Will post here if I get any new info.

Well, I've uninstalled Bitdefender for now and the warnings have gone away. Confirmed that it came from Bitdefender. (And no, I didn't decide to ditch Bitdefender entirely over this, it was just the metaphorical straw that broke the metaphorical camel's back considering I haven't been exactly pleased with their product recently.)

It's good to know where the problem is coming from. As i said last night only solution was to uninstall bitdefender and as I had a lot of stress and had to go through a clean install of windows and all software+ backups, I was not so hot to do that last night. Thanks for taking the time doing it and now that we know the root of the problem I think we can continue using the PC with bitdefender installed. It dose not seem to affect performance or reliability and the little warning has no real harm. I still hope they will fix it soon. Thanks a lot for your help trashbag :)

Apparently bitdefender is now checking the problem:

Bitdefender has released an update. After this update the problem is fixed. (at least no more error on my side!)
