Installing FortiClient on infected systems

The FortiClient installer always runs a quick AV scan on the target host system before proceeding with the complete installation. If the system is clean, installation proceeds as usual.

Any virus found during this step is quarantined before installation continues.

In case a virus on an infected system prevents downloading the new FortiClient package, use the following process:

  1. Boot into “safe mode with networking”. The FortiClient installer requires this mode to download the latest signature packages from the Fortinet Distribution Network.
  2. Run the FortiClient installer.

This scans the entire file system. A log file is generated in the logs subdirectory. If a virus is found, it is quarantined. When complete, reboot into normal mode and run the FortiClient installer to complete the installation.

Windows does not allow FortiClient installation to complete in safe mode. An error message is generated. Rebooting into normal mode is necessary to complete the installation.
