Wow, I didn't know this. This is a great option to filter out content. My problem is to also restricts sites like YouTube (to avoid watching a video when in the class). So, something that also helps me tune at the site-level.
My situation is far worse. The instructor assigns video that is on YouTube, but the kid would rather watch a different video. The assigned video is boring. It's more fun to watch a normal popular video.
So blocking YouTube won't work, yet most of YouTube needs to be blocked.
Yes, that is pathetic. Kaspersky allows whitelisting specific URLs. So, entire YouTube can remain blocked but specific URLs can still work. I would download YouTube video and then have my kid watch them if it is course related.
So it blocks "Malware and Adult Content", but that has never caused trouble in my family. What about the online games that distract from schoolwork, chores, and sleep? YouTube is full of stupid videos. You can even find games on Khan Academy!
