Our verdict on iMalware

iMalware is a free, browser-based tool for checking files against a database of known malware samples. It suits solo users and small teams who want a quick hash lookup without uploading a file. The browser computes an MD5 hash locally and compares it with the database; users can also enter MD5, SHA-1, or SHA-256 hashes directly. This is static, hash-based checking rather than a scan of how a file behaves, so it is most relevant when a known sample is the concern.

For routine lookups, iMalware supports multiple files or a folder and accepts up to 500 hashes per lookup. It also checks ZIP archives as a whole, but does not unpack them, so files inside an archive are not individually inspected through that feature. An in-memory EICAR test file is available. These functions make the tool useful for checking hashes in batches, but they do not turn it into an antivirus engine or sandbox analysis service.

The main boundary is detection coverage: a novel or modified malware sample may not match a known hash. iMalware also does not scan URLs or perform computer-wide scans. Choose it for free local hash checks and known-sample lookups; choose a broader security tool when you need behavioral analysis, URL checks, or an examination of the computer itself. Its narrow scope is a good fit for a focused lookup task, not a replacement for broader malware protection.
