Files signed by Piriform Software Ltd

Piriform Software Ltd

Piriform Software Ltd is a digital signature publisher name observed in ThreatInfo records. This page groups 5 signed files and shows whether those files are currently classified as clean, undefined, or detected.

A digital signature can help identify a publisher, but it does not always prove that a file is safe. Certificates may be abused, stolen, expired, or attached to modified installers, so the file hash and detection status should be checked together.
