Uploading Files to Avast FTP Server

 

You may need to upload files to our FTP server if you are a developer who joined our Whitelisting Program and you want to submit files to our Threat Labs for whitelisting.

Avast Threat Labs are notified automatically once you upload your files, which are then usually processed within 24 hours.

Note that you might not receive any feedback regarding the submitted files. However, if the files are whitelisted/confirmed as false positives by our Threat Labs representatives, your Antivirus client should automatically receive the update within the following 24 hours.

Uploading Files for Whitelisting

Uploading From Windows Devices

After compressing your files, ensure the device is connected to the internet, then upload the zipped folder to the Avast FTP server with any FTP client software using the following parameters:

• Protocol: SFTP
• Host: whitelisting.avast.com
• Port: 22
• Username/Password: Your account credentials received after joining the Whitelisting Program

 

If you do not have any FTP client software installed, you can install the free WinSCP software from winscp.net, then perform the upload as follows:

1. Open the WinSCP app
2. On the Login screen, provide the parameters listed above, then click Login to connect to the Avast FTP server
   1. When you log in for the first time, you may see a message asking if you want to continue connecting to an unknown server. This is expected behavior, and you can click Accept.

3. On the right side of the screen, double-click the data folder

4. On the left side, locate your zipped folder, then right-click it and select Upload... from the context menu

5. Click OK to upload the files to the server
   5. If the upload stops mid-progress, it cannot be resumed (you will need to repeat the upload).

Submit only those files for which you have the authorization to request approval. Do not submit game hacks, cracks, keygens, or similar apps. Also, upload only complete files. Partially uploaded or broken files and delta-update files won't be considered for analysis or whitelisting.

Uploaded files are only visible to our Threat Labs analysts. Avast does not collect any personal information from files submitted for whitelisting. We reserve the right to share the uploaded samples with other security companies for research purposes, along with the information that the whitelisted samples are virus-free. We also reserve the right to refuse to whitelist any application.

You are not notified about the whitelisting process. However, you can update virus definitions in Avast Antivirus, then scan the submitted files to verify that they have been whitelisted.
