What to verify before removal

Trojan.Ransom.Loki.CQQ (file analysis) should be handled as a recovery-sensitive report, not as a routine deletion task. Before removing files, isolate the affected system and compare the detection with the notes below so encrypted data, restore points, and backups are not damaged.

Start by comparing the local file name with B4F8AB8E00B348A1410D.mlw, then review the behavior notes for file-encryption activity, ransom notes, renamed documents, and unexpected recovery blockers. This helps separate a matching detection from a different file that only shares a similar alert name.

Observed file
B4F8AB8E00B348A1410D.mlw
  • Compare the suspicious file name with B4F8AB8E00B348A1410D.mlw.

  • Review the report for file-encryption activity, ransom notes, renamed documents, and unexpected recovery blockers so the cleanup is based on observed behavior, not only the label.
  • Disconnect the machine from the network before recovery work and avoid deleting encrypted samples until backups are checked.
