I'm using Bitdefender Total Security. (Build 26.0.25.84)
Recently, the 'bdservicehost' process is using 30% of CPU at all times.
I used Process Monitor to see what process is doing. Then, it was found that FSCTL_READ_USN_JOURNAL was continuously performed on drive C.
It has already deleted and attempted to reinstall the program, but it still occurs.
I ask for your help on this.
