Kaspersky blocks files with reason "could not be scanned by AV"

• Kaspersky blocks files with error "could not be scanned by AV" but file seems valid and can be opened with archive software.

Reply:

Check the Response node in the weblog transaction.

Possible reasons:

Scan timeout - try increasing scan timeout in Administration->System Settings->Scanning->Scanning Engines->Anti-Virus (Kaspersky)->Scanning Time Limit

Encrypted file - A file in the archive may be encrypted and Kaspersky fails to open it. This triggers a block of the whole archive with reason password protected.

Corrupt file - A file in the archive is corrupted and that's why the whole archive is marked as corrupted.
