Flash Installer is a rogue browser extension for Mac-compatible web browsing programs. The type of software that Flash Installer belongs to is better known under the umbrella term of browser hijackers.

The Flash Installer Virus will make unwanted changes to your browser.

Browser hijackers are very widespread on the internet and they’ve been around for ages. However, it wasn’t until recent years that software of this type became available for Mac operating systems as well. And as it turns out, variants like Flash Installer are only gaining momentum now.

The good news, however, is that Flash Installer is not a virus and browser hijackers don’t have malicious intentions. All these types of programs do is generate and showcase highly aggressive online ads such as banners, box messages and popups on the screens of the computers they infect. And they do this by embedding ad-generating components in the Firefox, Chrome, Safari or whatever your main browsing program is. These same components are often also responsible for facilitating annoying page redirects to various websites that have paid to be promoted in this way.

Another means by which browser hijackers like Flash Installer may choose to popularize certain websites is by setting them as the new browser homepage and/or its default search engine. And the only way you will be able to reconfigure your browser to its old settings is if you have Flash Installer thoroughly removed from your computer. Unfortunately, this is oftentimes easier said than done as the developers of such apps rarely want you to uninstall them – so they simply don’t include that option. But we have created a removal guide that will show you how to handle this process manually and you can find our guide just below the current post.

Flash Installer for Mac

Flash Installer for Mac operates on the basis of Pay Per Click and/or similar remuneration systems. This means that the developers of Flash Installer for Mac profit from the ads that are displayed on your screen by this software.

This should explain, by the very least, why the many popups and box messages are very often incredibly difficult to avoid. But there’s more that goes into these advertising practices. One is that hijackers like Flash Installer are usually involved in collecting browsing data from users, which may not be made known to said users. Furthermore, that information could be user to various other purposes that you may never come to find out about.

What is Flash Installer ?

Very often software like Flash Installer is mistakenly referred to as viruses. The good news is that Flash Installer is not malicious code and it cannot directly harm or damage your computer.

Nevertheless, software of this type is widely also regarded as potentially unwanted – in part because of its association with the risk of getting infected by viruses. This can happen, for example, as a result of being redirected to a page infected with Trojans and ransomware.
