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 1024 x 768
Internet connection or a local area network connection to a source (see Note 3) for 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 installing and running the product on systems that do not meet these requirements might be possible, we recommend prior usability testing based on performance requirements.

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