Submit Unknown Files for Analysis


CCAV awards a trust verdict of 'unknown' to a file after the following processes:

  • Files are checked against the local and cloud trusted vendor lists. If the file was published by a trusted vendor then it is considered safe.
  • CCAV consults Comodo's file lookup service (FLS) to see if the file is on the whitelist or blacklist.
  • If no trust verdict is provided by the above processes, CCAV declares the file is 'unknown'.
Unknown files are submitted to Comodo cloud for analysis. Depending on the settings, unknown files are submitted automatically or manually.
  • To configure the unknown file submission settings, click the 'Settings' icon on the top-left then 'Sandbox' > 'Sandbox Settings'



  • Enable / disable the option 'I want to enable 'Cloud Based Behavioral Analysis' of unrecognized....' as shown above.
  • If the above is enabled, unknown files will be automatically uploaded to cloud for analysis during the following actions:
  • Quick scan, full scan, certificate scan, folder scan and file scan (Click 'Scan' in the home screen and select the scan type)
  • Right-click a folder and select 'Analyze Content of this Folder in the Cloud'
  • When an unknown application is executed on your computer
  • Right-click folder / file and select option of 'Scan with Comodo Cloud Antivirus',
  • If the above is disabled, you have to submit unknown files manually to Comodo cloud for analysis during the following actions:
  • Right-click a folder and select 'Analyze Content of this Folder in the Cloud'



  • Click 'Needs submit permission' to upload for analysis
  • When an unknown application is executed on your computer



  • Click 'Submit file(s)' in the home screen under 'Valkyrie Analysis Results' to upload for analysis
Note - For quick scan, full scan, folder scan, file scan and scheduled scan there is no option to submit unknown files manually for analysis. So make sure that the option is enabled.
