After enabling Intrusion Detection I receive messages saying 'Files were found to be changed by some intruder'. What does this mean and how can we exclude this update from generating these reports?

This is because the URL filter has been updated and some of the files need to be updated because of the new URL database.

Here is how you can disable the URL update:

- Login using Webadmin

- Click on tracking

- Click on Update services

- Uncheck the enable update for the URL catagories

- Click on Save
