Built on ThreatSense.Net® advanced early warning system, ESET LiveGrid® utilizes data that ESET users have submitted worldwide and sends it to the ESET Virus Lab. By providing suspicious samples and metadata from the wild, ESET LiveGrid® enables us to react immediately to the needs of our customers and keep ESET responsive to the latest threats. ESET malware researchers use the information to build an accurate snapshot of the nature and scope of global threats, which helps us focus on the right targets. ESET LiveGrid® data plays an important role in setting priorities in our automated processing.

Additionally, it implements a reputation system that helps to improve the overall efficiency of our anti-malware solutions. When an executable file or archive is being inspected on a user’s system, its hash tag is first compared against a database of white- and blacklisted items. If it is found on the whitelist, the inspected file is considered clean and also flagged to be excluded from future scans. If it is on the blacklist, appropriate actions are taken based on the nature of the threat. If no match is found, the file is scanned thoroughly. Based on the results of this scan, files are categorized as threats or non-threats. This approach has a significant positive impact on scanning performance.

This reputation system allows for effective detection of malware samples even before their signatures are distributed to users via virus signature database updates several times a day.
