Instant YouTube Blocker

We all know that YouTube is one of the most distracting forms of entertainment that the Internet has ever produced, since it's quite difficult to efficiently work while trying to view the latest action movie trailer, cat videos, or do-it-yourself clips (albeit, listening to music is quite productive for some people).
Instant YouTube Blocker is a small-sized, ultra-simplistic and very effective tool that can help you in this regard. It doesn't come loaded with any kinds of configuration and can be handled even by inexperienced users.

Block and unblock YouTube access with one click

The interface is represented by a small window with a plain and simple structure that shows a large button. Clicking it immediately blocks access to YouTube, and it can be just as easily unblocked.
Keep in mind that the video sharing website will remain blocked even after exiting Instant YouTube Blocker, so make sure you don't accidentally remove it from the computer without restoring settings to default. It offers support for Internet Explorer, Mozilla Firefox and Google Chrome, among others.

Evaluation and conclusion

Since this is such an easy-to-use program with one clear goal, it's obvious that Instant YouTube Blocker comes with some downsides. For example, the app cannot be password-protected, which means that users you have restricted YouTube access for can easily revert settings by just launching Instant YouTube Blocker.
As we expected, its impact on system performance is insignificant, since it requires minimal CPU and RAM to work properly. No error dialogs were shown in our tests, and the tool didn't hang or crash. You can definitely use it to quickly restrict other users' access to YouTube, but you'll have to resort to a more powerful application if you prefer additional options and customization settings.
