Activation issue in ESET NOD32 Antivirus Posted March 6 Thank you for writing. I returned the product to the store and got my money back. He said he would return all this brand products and bring another brand or something to that effect. Now I am stuck with a original windows 7 Vaio laptop that cant get Microsoft updates and its windows defender stopped working in Jan 2020. I am reluctant to have it upgraded because the hardware change. In all fairness maybe I should have upgraded to 10 w hen the company offered it for free a couple of years ago. Good forum!
