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.

Free and simple antivirus software from Microsoft

The developer of Microsoft Security Essentials for Windows XP (32-Bits) is no longer providing support for the program. Although you can still download it, we can't guarantee that it will function correctly.

  • Easy to install and use
  • Automatic updates
  • Several scan types
  • Light and unobtrusive
  • Doesn't disinfect files
  • Too basic for expert users
  • No firewall

"Really The Best! And Free!"

Low CPU/Memory usage. I have used MSE for five years now, along with Malwarebytes and 9 Lab Removal Tool. Only had a few PUP's.

I have a old cheap laptop i like to test AV Products with and MSE is just as good if not better than the big names. Only MSE doesn't use all the resources the others do. Scheduled Scan works as it should. Updates sometimes twice in an hour. ( I have MSE set in *Registry* to check every hour) It is really the best AV Product out. It doesn't nag you, install other (Open Candy) Toolbars, etc, etc ... like the others do. No pop up's either. Just does it's job.
