Support: Uploading files to the Avast FTP server

How to upload files to the Avast FTP server

When contacting Avast Support with a technical or malware issue, you may be asked to upload specific files from your PC to the Avast FTP server for further analysis. To do so, follow the steps in this article:

Compress requested files to a password-protected archive

Before you upload a requested file to the Avast FTP server, compress the file to an archive (for example, a .zip, .rar, or .7z file) using the password virus.

Follow these steps:

  1. Download and run the installer for 7-Zip from www.7-zip.org to install the free file archiver on your PC.
  2. Select and right-click all requested files and, from the context menu, select 7-ZipAdd to archive.
  3. Under the heading Archive, provide a unique filename, such as your e-mail address, to identify your archive on our FTP server.
  4. Under the heading Encryption, provide the password virus.
  5. Click OK to create the compressed archive.

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

If you are unable to compress a file 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.

Uploading an archive with the requested files to the Avast FTP server

After compressing the requested files to a password protected archive, upload the archive to our Avast FTP server with any FTP client software, using the following parameters:

File protocol: Encryption: Host name: Port number: Login (username/password): Directory:

  • Ensure that you notify us each time you upload a file to our FTP server to ensure that the files are retrieved promptly.
  • Only upload files to our FTP server that have been requested by Avast.
  • You are unable to see any content in our FTP server, including any files you upload, because you have write-only privileges.

  1. Download and run the installer for WinSCP from http://www.winscp.net to install free FTP client software on your PC (keep the setup defaults while installing).
  2. Double-click the WinSCP icon on your desktop to run the FTP client.

  4. When the connection to Avast FTP server is established, double-click the incoming folder on the right side of the WinSCP screen.
  5. Locate the archive with the requested files on the left side of the WinSCP screen, right-click it, and select Upload... from the context menu.
  6. Click OK to upload the archive to the incoming folder on the Avast FTP server.

Provide the filename and password of the uploaded archive to Avast Support
