Submitting False Positives

 

When you contact our Business Technical Support with a technical or malware-related issue, you may be asked to upload specific files from your PC to the FTP server for further analysis.

Sending Files via Local Client

You may send a detected file in the local Essential/Premium/Ultimate Business Security client's Quarantine to be analyzed by our virus lab.

1. Open the local Antivirus client on the device that detected the file
2. Click on Protection in the left panel
3. Click Quarantine in the slide-out menu
4. Check the box next to the file you want to send
5. Click on the three dots next to the Delete button
6. Click Send for analysis in the menu
7. Select False positive and, if desired enter details, then click Send

Sending Files Manually

You can manually submit falsely detected files and URLs at https://www.avast.com/false-positive-file-form.php (If you are submitting a file larger than 50MB, see Submitting Larger Files via FTP Server below).

Submitting files/URLs is an automated process and you may not receive a reply or further information about the files/URLs you send. Please allow at least a few business days for your files and/or site to be analyzed. Once our virus lab representatives confirm the file/URL is a false positive, your Antivirus client(s) should automatically receive the update within the following 24 hours.

Submitting Larger Files via FTP Server

If your files are larger than 50 MB, you will need to submit them to the Avast FTP Server and send the file information to the Business Support team.

Preparing Files for Uploading

Compress your files to a .zip archive following these steps:

1. Download and run the installer for 7-Zip
2. Select and right-click all requested files and click 7-Zip > Add to archive from the context menu
3. Under Archive, provide your preferred archive name to identify it on our FTP server
4. Under Encryption, enter virus for the password
5. Click Ok to create the compressed archive, which will be located in the same folder as the original files

Uploading Files to FTP Server

Upload a file or an archive to the Avast FTP server with any FTP client software using the following parameters:

File Protocol	Encryption	Host Name	Port Number	Login (username/password)	Directory
FTP	No encryption	ftp.avast.com	21	anonymous/anonymous	/incoming

Only upload files to the FTP server that have been requested by Technical Support representatives, and notify your Support Agent when you upload files to the server. You cannot see any content on the server, even the files you upload.

After uploading an archive to the Avast FTP server, ensure that you notify Technical Support of the filename and password for the archive. Without this notification, we may be unable to locate your archive on our FTP server and analyze your files.
