Uploading Files to Avast FTP Server

 

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

• Support analysis: If you have been asked by our support agents to send larger diagnostic files (such as logs or memory dumps) for further analysis, or when you are Submitting Suspected False Positives.
• Whitelisting: 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.

If you are already in contact with our support agents regarding the upload, please ensure you provide them with the name of the uploaded folder so they can locate it on the server.

Preparing Files for Upload

Before uploading your files to the Avast FTP server, you need to compress them, i.e. put them in a zipped folder. Also, make sure to give the zipped folder a specific name (e.g. your email address) so we can easily identify it on the server if needed.

If you are unable to compress a file because it is flagged as suspicious by Avast, temporarily disable all Antivirus Core Shields, then try again.
