A lot of people might have been confused by this, I know I was. If you are using Grisoft’s AVGFree version 7.1, you’ll have seen various pop-ups telling you that it was being stopped. However, what that meant was that the product support for 7.1 was being stopped, and that you should upgrade to the 7.5 version, which is the same, but better, and still supported.
