Adobe Flash Player is a free software plug-in used by web browsers to view multimedia, execute rich Internet applications, and stream video on your Mac.

Adobe Flash Player is the most popular multimedia player plug-in available. However, recently there have been security concerns which has threatened its popularity as users seek safer alternative solutions. Opera, Firefox and Chrome contain built-in versions of Flash running in sandbox mode. This method is safer than running Flash as a plugin. However, currently the reality is that you still may need the Adobe Flash Player on your Mac because many websites will not work well if you uninstall it. Here I’ll show you how to install Adobe Flash Player and how to set it up correctly.

For enhancing the user experience and security, Adobe is always trying to improve Adobe Flash Player. However, sometimes when you view a website, a Flash Player upgrade popup appears. Most people would click the “update” button to update their Flash Player, but this could be a false popup used by hackers to compromise your Mac. This is a method hackers use to trick you into downloading adware and malware through a false popup.

Be careful and don’t trust any automatic updates of Adobe Flash Player. Here I will tell you how to install real Flash Player updates and set it up.

1. Go to the Apple menu bar and select System Preferences.

2. Select Flash Player.

3. Select the Updates tab and select “Allow Adobe to install updates (recommended)”. (Note: The Flash plug-in is officially updated 1~2 times a month, so selecting this option avoids frequent update.)

5. Click Check Now to confirm that you currently have the latest version installed.

If you had clicked a false popup and downloaded adware, don’t worry, the Apple App Store has many antivirus apps, such as Trend Micro’s Antivirus One, that you can use to do a free scan.

Follow the steps below in case you downloaded a fake Adobe Flash Player.

1. When you first install Antivirus One, click “Pattern Update” to make sure your virus pattern is up to date. We suggest you update the virus pattern every day.

2. After the first installation, we highly suggest you perform a full scan of your Mac to check all files for possible infections. The Full scan will take more than one hour.

3. If you still find adware and a full scan has not found any viruses, we recommend you use Adware Cleaner. You can access Adware Cleaner in the left panel of the Antivirus One window.
