New And Improved Features
    Smarter Scanner – Threats don't always enter in ways you expect. ESET Smart Security inspects SSL-encrypted communication channels like HTTPS and POP3S, and intelligently scans compressed files to find threats that other products miss. ESET's Smart Optimization feature makes file scanning faster than ever.

    Time-saving Firewall – The new Learning Mode saves time by automatically creating firewall rules by observing how you use your computer, while offering advanced firewall modes for power users.

    Upgraded Antispam – ESET Smart Security now takes care of annoying spam with a smaller, faster, and even more effective spam filter.

    Removable Media Security – Threats can enter your PC from removable media such as USB thumb drives. For self-running media, ESET Smart Security scans autorun.inf and associated files when the medium is inserted, in addition to scanning any file on any removable device when it is accessed, or during a full-scan of the media. Power users can adjust ESET Smart Security to perform additional levels of scanning on removable media.

    System Tools – ESET SysInspector and ESET SysRescue simplify diagnosing and cleaning of infected systems by allowing deep scans of system processes to find hidden threats, and creating bootable rescue CD/DVD or USB drives to help you repair an infected computer.

    Self Defense – ESET Smart Security has built-in technology to prevent malicious software from corrupting or disabling it, so you can rest assured your system is always protected.
