If Sophos detects malicious file which is present in removable storage, the alert will give which file path.
For example D://example.exe
Hello kumar raj
AFAIK the path will be what the file path is at the time of detection, for example you have a thumb drive that was assigned to E:\, and Sophos detected a file there, the path will be something like E:\path\to\file.exe.
But not c:\\
C:\ is usually assigned to a local drive; Sophos should look at whatever drive letter Windows assigns when the removable storage is detected.
What are you seeing, that this has come up?
