hi @gunnahafta ! ok, so the report says why it happened, and what type of anomaly it is:

 {
  "pid" : 10844,
  "is_64_bit" : 1,
  "is_managed" : 0,
  "main_image_path" : "D:\\temp\\hollows_hunter64.exe",
  "used_reflection" : 0,
  "scanned" : 
  {
   "total" : 19,
   "skipped" : 0,
   "modified" : 
   {
    "total" : 1,
    "patched" : 0,
    "iat_hooked" : 0,
    "replaced" : 0,
    "hdr_modified" : 0,
    "implanted_pe" : 0,
    "implanted_shc" : 0,
    "unreachable_file" : 1,
    "other" : 1
   },
   "errors" : 2
  },
  "scans" : [
   {
    "mapping_scan" : {
     "module" : "7ff63d890000",
     "module_file" : "D:\\temp\\hollows_hunter64.exe",
     "mapped_file" : "D:\\temp\\hollows hunter\\hollows_hunter64.exe",
     "status" : 1
    }
   },
   {
    "unreachable_scan" : {
     "module" : "7ff63d890000",
     "module_file" : "D:\\temp\\hollows_hunter64.exe",
     "status" : -1
    }
   }
  ]
 }

It is just about unreachable file:

    "unreachable_file" : 1,

that caused scan errors:

   "errors" : 2

because the original file could not be found. The other part of the report says what was the possible cause of this situation:

   {
    "mapping_scan" : {
     "module" : "7ff63d890000",
     "module_file" : "D:\\temp\\hollows_hunter64.exe",
     "mapped_file" : "D:\\temp\\hollows hunter\\hollows_hunter64.exe",
     "status" : 1
    }

possibly, the hollows_hunter64.exe was deployed from one location "D:\temp\hollows hunter\hollows_hunter64.exe" and then, during the execution, moved to other: "D:\temp\hollows_hunter64.exe". So the report explains that there is nothing to worry about.
