The manual download of the definition files takes a long time for those with slower internet speed and since it is a big file and once it is interrupted for whatever reasons , you have to start all over again. Why do you advice us to delete all the old definition files that we already have , in order to update the new files and for those of us if it doesn't work , like me , then we are stuck with no files at all? Wouldn't it be better if we had some kind of definition files , even though old ones , than have none at all and leave our pc's open to all kinds of risks? And why isn't Lavasoft tech support team think of a better way to update the definition files , than to tell us to delete all the old files we have for something that might or might not work? How long does Lavasoft expect this to go on?
