ess and eav? Hello, Please, enlighten me on these codes of yours. What does ess and eav stand for? While trying to download smart security, I got a set up with ess_nt32enu.msi and while trying to download set up for NOD32, I got eav_nt32enu. I now made payment for SMART SECURITY, the username started with EAV, is that not meant for NOD32 anti virus? I thought that my Eset Smart Security username should have started with ESS- Also, how do we determine the VALIDITY PERIOD?
