    I installed Bitdefender for the first time yesterday.

    I just noticed there are five files (most small but one is 48 megabytes and the other almost 4 megabytes) starting with bdr (bdr-bz01, bdr-cf01, bdr-im01.gz, bdr-ld01, and bdr0ld01.mbr) as well as a bdlog.txt file.

    Anyone know if these are trash files that can be deleted? Or are they important?

    I believe these are used to boot into a Linux environment so you can run a scan outside Windows. Don't delete these. I don't remember what Bitdefender calls it. Maybe, Rescue mode?

    It doesn't work in Windows 8 without disabling secure boot. At least it didn't when I was using BD.

    As Charyb says they are there for the rescue mode function that allows you to boot into a rescue mode to scan or remove threats, because it adds itself to the boot menu it backs up the mbr (bdr0ld01.mbr) bdr-im01.gz is the rescue mode compressed file. I wouldn't recommend deleting them in case it causes any boot issues in future.
