Scan an Endpoint for Malware

In addition to blocking the execution of malware, the Cortex XDR agent can scan your Windows and Mac endpoints and attached removable drives for dormant malware that is not actively attempting to run. The Cortex XDR agent examines the files on the endpoint according to the Malware security profile that is in effect on the endpoint (quarantine settings, unknown file upload, etc.) When a malicious file is detected during the scan, the Cortex XDR agent reports the malware to Cortex XDR so that you can manually take additional action to remove the malware before it is triggered and attempts to harm the endpoint.
You can scan the endpoint in the following ways:

Initiate a Full Scan from Cortex XDR

You can initiate full scans of one or more endpoints from either
Endpoint Administration
or the
Action Center
. After initiating a scan, you can monitor the progress from
Response
Action Center
. From both locations, you can also abort an in-progress scan. The time a scan takes to complete depends on the number of endpoints, connectivity to those endpoints, and the number of files for which Cortex XDR needs to obtain verdicts.
To initiate a scan from Cortex XDR:
  1. Log in to Cortex XDR.
    Select
    Response
    Action Center
    +New Action.
  2. Select
    Malware Scan
    .
  3. Click
    Next
    .
  4. Select the target endpoints (up to 100) on which you want to scan for malware.
    Scanning is available on Windows and Mac endpoints only. Cortex XDR automatically filters out any endpoints for which scanning is not supported. Scanning is also not available for inactive endpoints.
    If needed,
    Filter
    the list of endpoints by attribute or group name.
  5. Click
    Next
    .
  6. Review the action summary and click
    Done
    when finished.
    Cortex XDR initiates the action at the next heart beat and sends the request to the agent to initiate a malware scan.
  7. To track the status of a scan, return to the
    Action Center
    .
    When the status is
    Completed Successfully
    , you can view the scan results.
  8. View the scan results.
    After a Cortex XDR agent completes a scan, it reports the results to Cortex XDR.
    To view the scan results for a specific endpoint:
    1. On
      Action Center
      , when the scan status is complete, right-click the scan action and select
      Additional data
      .
      Cortex XDR displays additional details about the endpoint.
    2. Right-click the endpoint for which you want to view the scan results and select
      View related security events
      .
      Cortex XDR displays a filtered list of malware alerts for files that were detected on the endpoint during the scan.
