How to use this digest

Start with the MD5 hash, not the filename. If the hash or file path matches a system you manage, open the report, review the publisher and detection details, then scan the endpoint with GridinSoft Anti-Malware. ThreatInfo reports show whether GridinSoft already detects the file and which detection name is used.
