MacAppExtensions is a virus also known as Tapufind or which hijacks your browser and can deny you access to your regular search engines.

MacAppExtensions is a virus that hijacks your browser and is categorized as a potentially unwanted program (PUP).

Though the name might sound misleading due to the “Mac” component, the virus can be found on Windows systems too and is also known as “Tapufind.”

While the virus may not directly harm your system, it makes normal internet usage difficult, and the indirect consequences of allowing the virus on your computer are likely to be damaging in the long run.

The Nature of the Virus as a Browser Hijacker

MacAppExtensions viruses commonly arrive bundled with useful programs that users did choose to download, which means it can be hard to know how their system became infected.

This makes it all the more important to make sure that any new software you install is from reputable sources and that you check carefully through any add-ons that appear to be part of the package.

Once your system is infected, one of the first things the virus does is declare itself as the default search engine.

The URL,, becomes the new default and makes it impossible to return to your previous browser.

Tapufind appears to be very similar to the ChilliTab virus, with one of its defining characteristics being imitation popups that inform the user that browser updates from Mozilla, Chrome or Firefox have been successful. The popups prompt the user to accept them, which then leads to further viruses.

Tapufind also comes with numerous other popups including ads, surveys and notifications which should all be assumed malicious.

Using Tapufind as a search engine is also fraught with problems—aside from being bombarded with annoying popups, the search results typically include sponsored links which are dangerous in themselves.

This makes normal internet browsing near impossible. It is also thought that Tapufind is linked to another browser hijacker virus known as Safe Finder. Having the two working together on your system could be a serious risk.

Finally, aside from irritating popups and inadequate search results, the virus also has the capacity to track your internet use and gather personal information to be distributed to third parties.

This means that your browser is no longer private or safe to use with sensitive information.

Clearly, this not a virus that you want hanging around on your computer. If you have been infected, follow the steps below to remove it.

Once you click the “Download Now” button, most programs will open a dialogue box. Aside from the standard terms and conditions check box, there may be others which indicate bundled programs, likely to be adware or  viruses.

In your hurry to get to what you want, it can tempting to check whichever boxes are required for the download to start. However, this practice almost guarantees that you will also download an unwanted program.
