Other

  • System requirements of the operating system and other software installed on the computer are fulfilled
  • 0.3 GB of free system memory (see Note 1)
  • 1 GB of free disk space (see Note 2)
  • Minimum display resolution 1024x768
  • Internet connection or a local area network connection to a source (see Note 3) of product updates
  • Two antivirus programs running simultaneously on a single device causes inevitable system resource conflicts, such as slowing down the system to make it inoperable

Although it might be possible to install and run the product on systems that do not meet these requirements, we recommend prior usability testing to be done based on performance requirements.

note

(1): The product might use more memory if the memory would be otherwise unused on a heavily infected computer or when huge lists of data are being imported into the product (e.g. URL white lists).
(2): The disk space needed to download the installer, install the product and to keep a copy of the installation package in program data as well as backups of product updates to support the rollback feature. The product might use more disk space under different settings (e.g. when more product update backup versions are stored, memory dumps or huge amounts of log records are kept) or on an infected computer (e.g. due to the quarantine feature). We recommend to keep enough free disk space to support the updates of the operating system and for ESET product updates.
(3): Although not recommended, the product might be updated manually from a removable media.
