You know, I've used SD for years. Last week I gave the newest version a shot. I've never had any problems with SD. I'll be willing to bet, I'm just one of thousands. So, for one or two who have had a problem and then "advise" new users to "not" trust this software - well - I think YOU are mistaken. I've been watching this thread since Tony went missing. You bet I was concerned. As I and many others have said, we are not having any problems with Shadow Defender. Make sure your system is compatable with SD before you advise other people not to trust/try SD. I had tried several other products that would not work with my system before I got SD. Maybe SD won't work for you, try one of the others. There are others. Go try one.
