Abstract: In some implementations, a method includes receiving files provided for analysis by users, generating, from the received files, a batch including multiple files, and scanning each of the files in the batch using each of multiple different antivirus software programs to generate an antivirus output for each of the files. The scanning includes, for each of multiple computing units, generating a replica of the batch for the computing unit, and scanning, by the computing unit, each file in the replica of the batch using an antivirus software program assigned to the computing unit to generate a respective program-specific antivirus output for the antivirus software program for each file of the batch of files. The method includes generating, for each file in the batch, the antivirus output for the file from the program-specific antivirus outputs for the file, and outputting the generated antivirus outputs for presentation to the users.
