VIRUS SCAN

When this machine is connected to a network environment, it may be exposed to viruses and other attacks from outside. It is also possible to be infected with a virus via a USB memory device. There is a concern that a virus infecting the device may spread to other devices. By installing a virus detection kit, viruses can be detected and dealt with at an early stage to prevent the spread of virus infection.

  • The machine must be connected to a network and have access to the Internet. Connect to a LAN using the LAN connector of the machine or the wireless LAN function, and make the necessary settings by referring to " Network Settings". Also, see " Port Control", and the HTTPS client port must be set to "Enabled". In addition, if necessary, configure " Proxy Setting".
  • The virus scan settings are configured in [Virus Scan Setting] in [Security Settings]. The first time you enter [Virus Scan Setting], the software license agreement screen will appear. Read and agree to the terms of the agreement before using the virus detection kit.
