Flashinstaller is a web browser application classified as a browser hijacker. Flashinstaller can attach itself to common browsers like Safari, Chrome and Firefox and can change the configurations and the behavior of these browsers.


Flashinstaller on Mac

Usually this program is easy to spot because it replaces the existing browser-based search engine with a new one designed exclusively for producing sponsored search results. In addition, Flashinstaller places a new homepage and installs other helper components (such as redirect buttons, tools, toolbars, etc.) that allow unstoppable generation of pop-up ads and banners to on ever web page visited by the users. A lot of people who have Flashinstaller on their computer also complain that their web searches get automatically rerouted to pages they had not accessed previously, which adds to their irritation and the decision to permanently remove the intruding software from their Mac.

Thankfully, Flashinstaller can be successfully uninstalled without leaving any negative impact on the computer because, unlike viruses and malware threats such as ransomware or Trojans, it causes no harm to the system. People who want to remove this software can either use a removal guide, such as the one below, or a qualified removal tool for quick and easy deletion of all browser hijacker-related files.

Flashinstaller for Mac

Flashinstaller for Mac is a potentially unwanted program that web users sometimes mistake for a virus or malware due to its aggressive behavior. Fortunately, Flashinstaller for Mac is a relatively harmless application that only seeks to promote specific websites and their products and services by redirecting users to them.

The good thing about this program is that, once you uninstall it, you can use your browser and your computer as before which most definitely won’t be possible if you get infected with a real virus or malware such as a Trojan horse or Ransomware. The latter will most likely damage your Mac in a serious way while Flashinstaller, at its worst, will “hijack” only your web browser and force it to display various types of advertising content during your web surfing sessions.

What is Flashinstaller?

Flashinstaller is a potentially unwanted program that is used to deliberately encourage the appearance of different pop-up ads, banners and redirect links on the user’s screen. To operate more effectively, Flashinstaller usually integrates some page-redirecting tools and ad-producing components in the main web browser.

As we mentioned above, Flashinstaller lacks the dangerous features of computer viruses and malware but if not removed, it may still interrupt your web surfing significantly and easily become an unwelcome program inside your Mac. For one, such a program may not only be very intrusive, but can also have a quite negative impact on your online security and contribute to a potential encounter with security hazards. Just the fact that such a browser hijacker can install different third-party components in your web browser without requiring permission is enough to want to remove it. Not to mention that the search engine change, the new homepage, the shortcut buttons to different poor-quality pages, and the unwanted toolbars, can unnecessarily clutter the interface of the browser and deliver even more sponsored ads when you click on them.

The Flash Installer app

The Flash Installer app is a browser hijacker that typically doesn’t ask for permission to make changes to a Mac web browser. In most cases, the Flashi Istaller app updates the search engine and the homepage URL and starts to load the browser’s screen with aggressive advertisements, pop-up alerts and banners.

Changes made by Flashinstaller cannot be quickly reversed or uninstalled without the help of a professional removal tool or a manual removal guide. The instructions below, however, are created to assist you with this task, that’s why we encourage you to check them out.

We get asked this a lot, so we are putting it here: Removing parasite manually may take hours and damage your system in the process. We recommend downloading SpyHunter to see if it can detect parasite files for you.

The first thing you need to do is to Quit Safari (if it is opened). If you have trouble closing it normally, you may need to Force Quit Safari:

You can choose the Apple menu and click on Force Quit.

Alternatively, you can simultaneously press (the Command key situated next to the space bar), Option (the key right next to it) and Escape (the key located at the upper left corner of your keyboard).

If you have done it right a dialog box titled Force Quit Applications will open up.

In this new dialog window select Safari, then press the Force Quit button, then confirm with Force Quit again.

Close the dialog box/window.



To remove parasite on your own, you may have to meddle with system files and registries. If you were to do this, you need to be extremely careful, because you may damage your system.

If you want to avoid the risk, we recommend downloading SpyHunter
a professional malware removal tool.
