You are personally responsible for the security of the data that is stored on your computer, particularly for monitoring and restricting access to the data until it is submitted to Kaspersky.

Trace files are stored on the computer as long as the application is in use, and are deleted permanently when the application is removed.

Trace files, except trace files of Authentication Agent, are stored in the folder %ProgramData%\Kaspersky Lab\KES\Traces.

Trace files are named as follows: KES<service version number_dateXX.XX_timeXX.XX_pidXXX.><trace file type>.log.

You can view data saved in trace files.

All trace files contain the following common data:

  • Event time.
  • Number of the thread of execution.

    The Authentication Agent trace file does not contain this information.

  • Application component that caused the event.
  • Degree of event severity (informational event, warning, critical event, error).
  • A description of the event involving command execution by a component of the application and the result of execution of this command.

Kaspersky Endpoint Security saves user passwords to a trace file only in encrypted form.

Contents of SRV.log, GUI.log, and ALL.log trace files

SRV.log, GUI.log, and ALL.log trace files may store the following information in addition to general data:

  • Personal data, including the last name, first name, and middle name, if such data is included in the path to files on the local computer.
  • Data on the hardware installed on the computer (such as BIOS/UEFI firmware data). This data is written to trace files when performing Kaspersky Disk Encryption.

  • Your email address or a web address containing the name of your account and password if they are contained in the name of the object detected.
  • Websites that you visit and redirects from these websites. This data is written to trace files when the application scans websites.
  • Proxy server address, computer name, port, IP address, and user name used to sign in to the proxy server. This data is written to trace files if the application uses a proxy server.
  • Remote IP addresses to which your computer established connections.
  • Message subject, ID, sender's name and address of the message sender's web page on a social network. This data is written to trace files if the Web Control component is enabled.
  • Network traffic data. This data is written to trace files if traffic monitoring components are enabled (such as Web Control).
  • Data received from Kaspersky servers (such as the version of anti-virus databases).
  • Statuses of Kaspersky Endpoint Security components and their operating data.
  • Data on user activity in the application.
  • Operating system events.
