What is a DNS cache poisoning attack? < --No Response @ ESET Support forum here @ Wilders!! I have intalled ESS V. 22.214.171.124 It is a known issue of ESS latest version or ESS V. 4.2? I have not read @ Avira about this issue Only affects ESET products? Is this a vulnerability of ESET products? This is the ESET Knowledgebase about DNS cache poisoning attack http://kb.eset.com/esetkb/index?page=content&id=SOLN2933 @ the web site above explain the solution, but not explain why users are receiving this notification. My Eset Smart Security 5 alert me with this message DNS cache poisoning attack, so I used an acronis image to get the system back again, but know ESET products made me lose confidence, with the Acronis Image I do not want to be in the middle of something and suddenly get the alert.
