dll files within the Windows System32 folder appears and reads CryptnetUrlCacheĪt the same time bdservicehost.exe begins reads of. I captured video of my disk activity in Resource Monitor and so I am able to describe roughly what BD does during these scans:

I want control of this scan and the ability to choose when it occurs and what drives it can or cannot scan. I do not want these scans running every single time I turn on this system. These are all set to sleep after 20mins and two of them are slow archive drives that can be noisy when doing a lot of activity. The reason this is an issue to me, is because I have 3 high-capacity mechanical drives. Indicating to me that the scans are caused by BD alone. When BD was completely uninstalled, I monitored my system and nothing occurred after one hour in terms of unusual disk access. Just to get this out of the way, I have already reinstalled the client and later went as far as uninstalling it completely and installing it again fresh from a new download. BD system updates are set to 1 hour by default, but I have since changed it to 2 hours and the scans still occur after one hour (the update runs as it should later). Nothing appears in the Notification tab, other than initially these scans coincided with system updates. I have no scheduled scans set – never have. The email support takes multiple days to get a reply and so far all Ive got back is try reinstalling – which I already did whilst waiting.Įxactly 1 hour after my system has booted into Windows, BD (more specifically bdservicehost.exe) begins a scan of all of my system drives which lasts about 10 minutes and then stops.

Someone else has replied on Reddit that they have the same issue, and we have both narrowed it down to being BitDefender (henceforth referred to as BD). I have already posted this fault on Reddit and also had some back and forth with email support. Ryzen 5800x, 32GB RAM, 1xNVMe (OS), 1xSSD, 3xHDDs Internet Defender (5 Device, 3Yr licence)

Bitdefender full scan took 20 hours
