Malware MD5 or file search
Put the MD5 hash of a file in the search box to check its reputation in the Anti-Virus Cloud Engine.
The service queries our database of unique malware and clean file samples by the MD5 hash of a file. If the file is known, you will see its risk level, size, name and, for malware, the detection name.
The MD5 hash function is cryptographically weak. ACE uses several hashes internally, but MD5 search is the most popular with people.
The MD5 hash database is not a substitute for a security/antivirus solution; it provides an additional layer of detection that helps you identify known suspicious files.
