Submission of samples for analysis

If you find a suspiciously behaving file on your computer or suspicious site on the internet, you can submit it to the ESET Research Lab for analysis (may not be available based on your configuration of ESET LiveGrid®).


Do not submit a sample unless it meets at least one of the following criteria:

  • The sample is not detected by your ESET product at all
  • The sample is incorrectly detected as a threat
  • We do not accept your personal files (that you would like to scan for malware by ESET) as samples (ESET Research Lab does not perform on-demand scans for users)
  • Use a descriptive subject line and enclose as much information about the file as possible (for example, a screenshot or the website you downloaded it from)

Sample submission enables you to send a file or a site to ESET for analysis using one of these methods:

  1. Using the sample submission dialog can be found in Tools > Submit sample for analysis.
  2. Alternatively, you can submit the file by email. If you prefer this option, pack the file(s) using WinRAR/ZIP, protect the archive with the password "infected", and send it to
  3. To report spam or spam false positives, see our ESET Knowledgebase article.

With Select sample for analysis opened, select the description from the Reason for submitting the sample drop-down menu that best fits your message:

File/Site—The path to the file or website you intend to submit.

Contact email—This contact email is sent along with suspicious files to ESET and may be used to contact you if further information is required for analysis. Entering a contact email is optional, select Submit anonymously to leave it empty.


You will not get a response from ESET unless more information is required from you. Each day our servers receive tens of thousands of files, making it impossible to reply to all submissions.

If the sample turns out to be a malicious application or website, its detection will be added to an upcoming ESET update.
