Just brought some software from a company called bookami. You purchase the software online and they send you a link to be able to download which can only be put onto 1 pc. I have tried and tried and it wont allow this software each time saying "heuristic virus. detection of a threat based on mailware". I have been told by others who have downloaded it its ok with other anti virus software companys. Someone even told me to turn off my nortons and then download the software as they had the same problem. All I want to do is resolve this problem as I have never had a problem with norton until now.
