Apps & Games content ratings on Softonic

Content ratings help you understand the type of content you might find in an app or game, so you can decide if they are suitable for you and your family.

What do the ratings actually tell me?

Content ratings describe the minimum age we feel the content is suitable for. It does not indicate that the app was specifically designed for that particular age, or if a certain level of skill is required to play the game or use the app.

Where can I find the content ratings?

You will find the content ratings on every app or game page.

Why are some apps or games unrated?

If an app or game does not have a rating, it means that it has not yet been rated, or it’s been rated and we’re working to update the page.

Rating Systems

Softonic uses the rating systems by PEGI and ESRB. The ratings you see may vary by country or region.

Previously known as Windows Antispyware Beta 1, Windows Defender (Beta 2) is a free program that helps protect your computer against pop-ups, slow performance, and security threats caused by spyware and other unwanted software.

It features Real-Time Protection, a monitoring system that recommends actions against spyware when it's detected, and a new streamlined interface that minimizes interruptions and helps you stay productive.

New name, but more or less the same as Windows Antispyware. I don't really trust the real time protection. For that I prefer paying for a full suite that will really do the job. This program is a bit of a mess to install, what saves it is that it is (luckily) completely free. Seems to update regularly too. I'll leave it on just in case, but definitely won't rely on it too much.
