Your options

If you've received an alert, then you have 2 options:

  • authorize the file
  • send the file to the lab for analysis

Authorize the file if it's from a trusted source.

Send it to the lab for analysis if:

  • you trust the file, but it generates alerts.
  • you don't trust the file

To reduce the chance of unwanted detections, Sophos HIPS should be set to 'Alert only' mode for the duration of any software installations.

Sending a file to the lab?

When you complete the sample submission form, please give a reason for your submission and mention this "HIPS/" detection.
