DNS Cache Poisoning Attack warning

Hi Experts,

We recently upgraded a client to ESET Smart Security (ESS)  from ESET NOD32. Since then, every few days the client receives a warning from ESS saying, "Detected DNS Cache Poisoning Attack" and gives the IP address where the attack is being detected from, which is the IP address of the router.

I'm aware that some antivirus programs which can detect DNS cache poisoning attacks also give false positives. Any idea how I can tell the difference between positive and false-positive detections in this regard?

Its antivirus issue see the below post and update your firewall.

"The erroneous "DNS cache poisoning attack" detections should be fixed in the next build of the firewall module (1072 probably). They used to occur when responses from a DNS server did not match queries."
