Adobe Flash Player has become less popular as years go by because of the serious security issues it brings. But millions of websites still use this platform, which is why people who need to access these sites have to download and install Flash Player.

If you do need to get Flash Player on your computer, here’s one thing you should remember: Adobe Flash Player is free to download and install. If the website you’re getting it from requires you to pay money (even if it’s just a few cents), you’re likely looking at a scam.

This was what happened with a malicious app that was found on the Google Play Store. The app was called F11 and promised to install Flash Player in users’ Android devices — but only after they paid €18 via PayPal. Once they made the payment, they were then directed to install Firefox and Dolphin browsers on their phone.

Here’s what’s wrong with this: first of all, Adobe Flash Player is no longer officially supported by Android 4.1 Jellybean and above. So, no matter how much you pay, you won’t be able to officially download Flash Player for your Android device (unless it’s running on Android 4.0 and below). Second, Firefox and Dolphin browsers have built-in support for Flash Player and can be downloaded for free. So, anyone who downloaded F11 and followed its instructions basically paid €18 to install something that was was offered for free.

F11 has already been removed from the Google Play Store, but it’s not an assurance that other scams wouldn’t be developed in the future. To avoid them, always remember that downloading Adobe Flash Player on your computer is free. If you don’t have Flash on your computer, get it from the official download page at get.adobe.com/flashplayer. And, if you’re using an Android device, simply download Firefox, Dolphin Browser, and other reputable Flash-supporting mobile browsers from the Google Play Store.
