Starting after Avast found a virus on my PC and quarantined all instances of it, when I now do a Quick Scan, at the end it presents a box containing this message: “Disk\?.…{+} Boot Record Error: The parameter is incorrect (87)”. It’s not described by Avast as malware, but a file that could not be scanned. Instead of the usual options to quarantine or delete, I only have a Close button and a ? button. The ? button takes me to Avast help, where there is no mention of this message, so it’s useless.
What does this mean? The computer appears to run perfectly, neither Avast nor Malwarebytes nor ESET online scanner find anything on the computer and there’s no indication anything is wrong with the Boot Record (boots and runs as it always has).
Ran chkdsk on the DATA drive (E:), but it would not run on C:. . . I think because my C: is a Samsung SSD. In any case, I ran Avast Quick Scan again, and the same message came up.
Although I said I could not run chkdsk on my SSD, apparently it DOES run; it just doesn’t put anything on the screen like I’m used to with an HDD. But after running cmd, entering “chkdsk /f” while the path is C:, then rebooting, the screen goes black for a minute or so, after which Windows loads. Chkdsk on a SSD, of course runs VERY fast – so fast it probably can’t put anything on screen. In any case, after doing chkdsks on both the SSD and HDD, then running Avast Quick Scan, the same message appears.
No path; just “Disk\?{+} Boot Record” “Error: The parameter is incorrect (87)”. And per my original post, it’s not described by Avast as malware; just a file that could not be scanned.
The single malware I found in all of the 258 line items in the quarantine chest is VBS:Agent-ACW [Trj]. The path to 98% of them was C:\Users\Donald\AppData\Local\Microsoft\WindowsLive Mail\Personal\Inbox (or) Sent Items (or) Storage Folders. The last 5 items were:
Actually it cannot scan it; that what the message says: “SOME FILES COULD NOT BE SCANNED”, under which it has what looks like a paper folder tab that says “Warnings”. It would be better if I could attach a screen dump, but this forum only allows text or direct picture files (.jpg, .gif, .png) as attachments and I have no idea how to save a screen dump in those formats.
