I’m receiving a constant warning when quick scanning with the current free version of Avast that “Some Files Could not be Scanned”; specifically “Disk\?\Volume{long alphanumeric string}{+}{+} Boot Record” with the message “Error: The Parameter is Incorrect (87)”.
This only occurs on a quick scan, not a full scan, which comes up as clean. Malwarebytes also pronounced a clean bill of health. There hasn’t been a noticeable slowdown of the computer or any of the things I normally associate with trouble (odd behavior, blue screens, strange processes running, etc.)
Running CHKDSK produced no change. I then ran a boot scan, which came up with Win64:BullSave-B [Adw] and Win64:Adware-C [Adw], and seems to have removed them. However, the warning has persisted.
Searching this site, I found https://forum.avast.com/index.php?topic=153635.0 which seemed a similar problem, down to the Samsung SSD and separate HDD. That thread doesn’t seem to reach a resolution, though.
I’d be grateful for any assistance in determining the cause of the issue, and whether or not it is a problem moving forward
