I have been a NOD32 user for 4 years, my license recently expired. So I used Avira for a while, then after being tired of so many false positives, I uninstalled it and tried AVG, and then Avast, they were all the same (Avira was the best of the FREE solutions), finally I tried Microsoft Security Essentials....that is a POS program....it took about 15 minutes to update only on my 2.4 GHz CPU and 4 GB Ram.....a scan of drive C: took about 2 hours (only 38 GB of data), I uninstalled it right away and purchased a 2 year license for ESS valid for use on 2 computers. My questions is.....will this ESS license work if I only choose to install NOD32 AntiVirus without the Firewall component? Not gonna do this as it is dumb but I just want to know out of curiosity. Are they inter-compatible since ESS is the more expensive product?
