Certificate review summary

Use the file hashes to verify this signature

ThreatInfo groups the signed files above so you can compare exact hashes and detection labels. A signature name alone is not enough to decide whether a file is safe.

Recommended checks

  • Open any matching file report and compare the MD5 hash.
  • Confirm the file path and download source before trusting the binary.
  • Run a GridinSoft scan if the signed file appears unexpectedly.
