# Recommended post-installation tasks

Perform these tasks to make sure that the protection configuration does not affect the business routines.

> [!NOTE]
> Note
> 
> For a fresh installation, Trellix recommends updating the DAT to the latest version. Since the DAT version 0999 is used to reduce the product footprint, you must update the DAT to the latest version immediately after installation to protect your systems from malware threats. The DAT version 0999 detects only the EICAR test file.
