Uploading files to the Avast FTP server

You may need to upload files to the Avast FTP server for either of the following reasons:

  • An Avast Support agent has requested that you upload specific files from your PC for further analysis.
  • You need to submit files to Avast Threat Labs for whitelisting.

Select the relevant tab below for instructions according to your issue type.

You cannot see any content on the Avast FTP server, even the files you upload.
 

Prepare files for upload

Before uploading files to the Avast FTP server, compress the files to a ZIP archive by following these steps:

  1. Download and run the 7-Zip installer from www.7-zip.org to install this free file archiver on your PC.
  2. Select and right-click all requested files, then select 7-ZipAdd to archive... from the context menu.
  3. Under the heading Archive, enter a name to identify the archive file on our FTP server (for example, your email address).
  4. Next to the heading Archive format, use the drop-down menu to select zip.
  5. Under the heading Encryption, tick the box next to Show Password, then provide the password: virus.
  6. Click OK to create the compressed archive.

The newly compressed archive is saved in the same folder as the original files.

If you are unable to compress a file that is flagged as suspicious by Avast Antivirus, temporarily disable Avast active protection by right-clicking the Avast icon in your system tray and selecting Avast shields controlDisable for 10 minutes.
