Hi Laurens,

If you are seeing random pop-up ads asking to update Adobe Flash Player, then your computer is infected with an adware.
These pop-up ads are not from the developers Adobe Flash Player and are used by cyber criminals to spread adware.

Therefore, if you are browsing the Web and see a notice pop up about the need to update Reader, there are several steps you can do to be sure bout the update is legitimate or not.

Step 1: Do not trust it
Immediately be skeptical of any automatic software update, especially those for Flash or Reader. Instead of accepting it and downloading the update, check the interface for any apparent typos or grammar errors, and if found, then close it down.

Additionally, check online by simply doing a Google search (or more accurately visiting Adobe's support site) to see if any updates have been recently issued.

Step 2: Standalone application
Adobe's updates are automatically distributed via utilities such as Update Adobe Flash Player, which are run from the Adobe Flash Player Install Manager program that is installed when you install Flash or Reader. To see if this program is what is running, right-click the installer icon in the Dock and select the option to show it in the Finder.

If the program is in your downloads folder, or somewhere in your user account, then do not trust it and throw it out. However, if it is in the /Applications or /Applications/Utilities/ folder, then it suggests the program is legitimate, since installing to these locations would first require a username and password.

Step 3: Quit your browser
Often malware will be presented as a download from within a specially crafted browser window that displays a Web page which is intended to look like a program running on your system. If you see a notice to install Flash, and then quit your Web browser and the notice goes away, then this is a good indication that it is not legitimate and is likely an attempt to lure you into downloading malicious software.

Step 4: Choose notify for updates installation
Avoid malware attempts when updating your programs (any software, and not just Adobe's) by avoiding the automatic update solutions altogether.

Instead, enable them to notify you when an update is available, and then only download the update directly from the developer. By doing this you will be sure the software you download is legitimate and up-to-date.
