My ESET Smart Security System has alerted me with the message ‘Detected DNS cache poisoning attack’. Should I need to uninstall the ESET software or it is some other issue? How to repair it?
No, you don’t need to uninstall the ESET Smart Security software. Indeed, DNS cache poisoning or DNS Spoofing is a hacking attack in which the internet traffic is diverted from the intended users and towards the fake systems. To fix this issue:
• First, determine if the detected IP address falls within the range: 172.16.X.X – 172.31.X.X, 192.168.X.X, 10.X.X.X where X = 0-255
• If it is in the above range, go to ESET Smart Security software. Press F5 key, and then Rules and Zones under Personal Firewallin the Network tab.
Click on Setup under Zone and rule editor.
Next, select the Zones tab, and choose Addresses excluded from active protection, and then click on Edit.
In the Dialog box, click on Add IPv4 address, and enter the detected IP Address in the single address field. Click OK until Advanced setup tree gets exit.
• If it is not in the safe range, then download the DNS-Flush.exe tool, run the file, restart your computer and then run the computer scan.
