I went from Avast Home Free and updated to 5.0.396. I then decided to upgrade to Avast Pro Anti virus. Everything looks and works great except the Sandbox feature does not work. I do not see a special window or red line surrounding the area. Do I need to re-install and then if I do, how about the license for the Pro version? Will Avast update in the future take care of this problem. What a mess!
