Submitting Samples

If you identified suspicious files, you may submit them to us. Sample files for submission must be in ZIP format and should be password-protected. To submit a ZIP file, file compression software such as Winzip must be used. A trial version of Winzip is available here.

To compress a file, please follow the steps below:

  1. Right-click on the file and select Add to Zip.
  2. Enter a file name for the zip file.
  3. On the Options menu, choose Encrpyt. In the input box, type virus. This serves as the password for the zip file.
  4. Send the sample through the following channels:
