Upgrade to the latest version

Many of the issues you might be experiencing with your ESET product have been resolved in the latest version. We highly recommend that you upgrade to the latest version:

 


Occasionally after installing ESET Smart Security, the false-positive detection of certain system processes can cause a temporary loss of Internet connectivity. Please follow the steps below to configure your ESET Smart Security Personal firewall to prevent the false-positive detections and restore your internet connection:

 

  1. Open ESET Smart Security. How do I open my ESET product?
     
  2. Press the F5 key to display the Advanced Setup window.
     
  3. From the Advanced Setup tree on the left, click Personal firewall → IDS and advanced options.
     
  4. In the Intrusion detection section, deselect the following options:

              ESET Smart Security 4.0 and 3.0:

    ESET Smart Security 3.0 only:

    • ARP Poisoning attack detection
    • DNS Poisoning attack detection
       
    • TCP Desynchronization attack detection
    • Reverse TCP Desynchronization attack detection

     

    NOTE:

    These attacks occur between the client and DNS/ARP authority and are not a risk for users with a NAT device. Deslecting the above options will not pose a risk to users with a router, Wi-Fi, or other local NAT device. Users who do not have a NAT device should use ESET NOD32 Antivirus instead and use the built-in Windows Firewall.
