  1. USB Mass Storage Class driver must be preinstalled. Automatic mounting is recommended.
  2. The file size of virus definitions is increasing daily to keep up with the growing number of viruses. The memory capacity required for operation has increased accordingly, and the memory capacity required may increase in the future.
[Note]
  • Virus definition file sizes are increasing to accommodate the growing number of viruses.
    Accordingly, the memory capacity required for operation may be greater than the values listed in "Operating Environment/Product Specifications" above.
  • By creating paging files (virtual memory), data processing beyond physical memory becomes possible.
    *Normally, the settings are automatically created by the OS.
  • Please be sure to download the latest virus definition files when running virus scans. Also, please check the Trellix website for the latest virus information.
  • The Trellix program built into this product does not remove the computer virus itself that it finds, but rather deletes the files infected with the virus. (It does not delete infected files when set to scan only.) If the OS is infected, it will delete the infected OS files themselves, which may result in the host machine being unusable until a new, uninfected OS is installed.
  • Viruses that have infected system files may not be removed. In such cases, it may be possible to remove them by downloading a special removal tool from the Trellix website.
  • Viruses that infect system memory cannot be removed; check the Trellix website for removal instructions.
  • New strains of viruses are found every day. Please run a virus scan with the latest virus definition file as it may not be able to detect or remove them.
  • If the registry has been rewritten by a virus, the product does not have the ability to repair the registry, so the system may not boot normally after the virus is removed.
  • When your license for this product expires, you will no longer have access to the latest virus definition files. No protection is provided or warranted by the McAfee Program after the license expires. In no event will McAfee or its distributors be liable for any damages resulting from your continued use of the Product after your license has expired.
  • There are some viruses that cannot be removed by this product. Please check the Trellix database for such viruses and take appropriate measures.
  • This product can detect viruses supported by Trellix by updating to the latest virus pattern files, but is not guaranteed to detect all viruses. Please note that some viruses, such as encrypted files and compressed files with passwords, may not be detected.
