I've been a long time supporter of double twist and I love it. I even bought the wireless sync add-on. On June 10, 2011, there was an update so I updated the program on my computer. When I tried to install it, AVG popped up and said that the new doubletwist was a virus. I searched doubletwist's website support and a few people also had this problem as well. The thing that bugs me is that the developer is not even coming forward about it. Anyone else have this problem?
