My laptop has already the Eset Nod32 antivirus installed with my paid subscription. But today I have re-installed the OS in my laptop. So, now how do I re-install the Eset Nod32 antivirus? Because on the Eset Home , it's still showing my laptop device as connected to my paid subscription. Do I disconnect on the eset home and reconnect again? Please help to advice. Thank you.
