I've been using for years Mc Afee and am thrilled by the product. This time I had trouble installing the download does not work out. Called telephone support, the nice lady turned on the computer and has everything installed and documented properly. Is now running smoothly. The computer was a little outdated and there were conflicts with old MS-Visio. Conclusion: bring computers to the latest version and the thing runs like clockwork. Then for the second computer I got from the lady again the complete procedural and installation instructions via email, also you asked then, even after the state of play.
