With this service, you can upload AVZ quarantine files for analysis.

Files from quarantine are examined and then used to update the clean file database, the malware detection database, and the heuristic analysis database.

Service usage rules:

Only quarantines created by the AVZ utility can be uploaded. Uploading other files is automatically blocked;
The upload is completely anonymous. However, after completion, the service provides the MD5 checksum of the uploaded quarantine, which can be used in email correspondence for file identification;
The maximum upload size is 250 MB; larger files are ignored;
If the quarantine file exceeds 250 MB, it should be uploaded to a file-sharing service with a download link provided in this topic.

To automatically collect all unrecognized and suspicious files, you need to:
