I have used nod32 for some time and my licence has just expired. I have now decided to drop nod and am moving to avira. So can someone please tell me the difference between avira free and avira premium please? I know there is no e-mail protection and no spyware/adware protection in the free version but that doesnt bother me as i already have a SAS pro licence and dont need e-mail protection. Apart from that, are there other differences in scan speed, updates, or detection?
