DescriptionThis article explains how FortiClient Heuristics works.
ScopeAll FortiClient users using the Heuristics feature
SolutionHeuristics scanning can be enabled in two profiles within the FortiClient. Heuristics scanning can be enabled for the file system
in
AntiVirus & AntiSpyware > Settings > Advanced Settings and selecting
Heuristic scanning.
Once enabled FortiClient software uses heuristic techniques to scan files to find the unknown viruses and threats that have not yet been cataloged
with signatures. Heuristics looks at the characteristics of a file, such
as size or architecture, as well as the behaviors of its code to determine
the likelihood of an infection, and subsequently quarantines any file it deems suspicious based on these checks.
Heuristics scanning can also be enabled for checking threats coming from email this can be enabled by going to
AntiVirus & AntiSpyware > Settings > Email and selecting
Email attachments heuristics scanning.
The same heuristics principles applies to email attachments as to the file system, file check.
