The improved Ransomware Shield uses heuristic monitoring to uncover threats, such as unwanted programs hidden in the system Registry.ĮSET is one of the first security programs to look for threats within the Windows Management Instrumentation (WMI) repository, which stores the system's metadata and definitions that the operating system and apps use to function. ESET distributes new malware signatures and other updates to its 110 million users as needed.Īll three ESET security suites have dedicated anti-phishing defenses, block script-based attacks and protect the Unified Extensible Firmware Interface (UEFI) start-up code. New potential threats are uploaded to the company's Live Grid cloud lab where machine learning techniques dissect the software. In addition to conventional comparisons of suspect files to a database of known threats, ESET's malware engine continually monitors the behavior of key system activities for the signs of an infection. Linux systems need to have Debian, Fedora, Open SUSE, Red Hat or Ubuntu distributions and Android devices require version 4.1 or newer. The ESET applications work with Windows 7 (with Service Pack 1), 8.1 and 10, plus Macs running macOS 10.12 (Sierra) through 11 (Big Sur). It does, however, lower the price if you buy two or three years of protection at once. Unlike its peers, ESET does not discount the first year of coverage for any of its antivirus suites.
