Cold Turkey (Basic version) is a clever little tool that can help you stay focused on your work by blocking you from accessing your favorite time-wasting websites. Websites can be grouped into three lists so that you can easily select which group to block at certain times. You can configure how long you want to block yourself from those sites, which can be anywhere from just a few minutes to up to 3 days. Once the time has expired, Cold Turkey will automatically re-enable access to the blocked sites.The sites that you choose to block will be unavailable in all browsers on the computer. Once you hit that button to start blocking, there is no way back! The program will not let you cancel the blocking until your self-imposed blocking period has expired! Cold Turkey uses the Windows HOSTS file feature to block the selected sites, which may cause some security applications to alert you of a HOSTS file change - you can safely ignore any alerts.The free Basic version only supports blocking for up to 3 days. A Pro version with application blocking and additional features can be purchased for about $15.
