Safety FAQ

Common questions about eicar_com.zip, answered from the scan data above.

  • eicar_com.zip appears safe. 14 of 76 antivirus engines report it clean, with only 62 low-confidence detections that read as false positives. As a habit, only open files you downloaded from the official source, since attackers sometimes distribute trojanised copies of legitimate software under the same name.
  • eicar_com.zip is a compressed archive, about 184 bytes. Our analysis found no threat indicators for it. A file's name can be reused by different files, so we identify it by its cryptographic hash (below).
  • 62 of 76 antivirus engines flagged eicar_com.zip, 62 of them as outright malicious. A small number of detections can include false positives, so we weigh which engines flagged it and what else the file does, not just the raw count.
  • Yes — this exact file is a known, catalogued malware sample in the abuse.ch MalwareBazaar threat-intelligence feed, first seen on July 3, 2024. A confirmed listing there is strong, independent evidence that the file is malicious.
  • The SHA-256 hash of eicar_com.zip is 2546dcffc5ad854d4ddc64fbf056871cd5a00f2471cb7a5bfd4ac23b6e9eedad, and its MD5 is 6ce6f415d8475545be5ba114f208b0ff. This hash is the file's unique fingerprint — two files with the same SHA-256 are identical. Use it to confirm you're looking at exactly this file (not just one with the same name) when comparing against antivirus databases or a download's published checksum.
  • Based on this scan, yes — eicar_com.zip shows no threat indicators. The important caveat is source: make sure you downloaded it from the official website or a trusted store, because attackers sometimes distribute malware-laced copies under a legitimate file's name. If your own antivirus flags it while we report it clean, that is most often a false positive, but verify the source before overriding your antivirus.
  • This report reflects the scan run on April 20, 2026. Because a file's hash never changes, the identity of eicar_com.zip is fixed — but antivirus coverage improves over time, so a file that looks clean today can pick up detections later (and vice-versa). If you need the latest picture, MalwareTips staff can re-run the analysis from scratch.

Unknown files are temporarily processed and submitted to VirusTotal. MalwareTips does not retain the binary after processing. Only the scan result (hash, detections, verdict) is retained so the next person who scans the same file gets an instant answer. If you ran this file on your computer and are worried, scan your system with an up-to-date antivirus and change critical passwords from a different device.
