Getting malware on your Mac can be downright annoying and dangerous at the same time. Most of them get into your Mac without you knowing how or when they were installed, making the removal process more challenging. On top of that, most of these malicious apps and programs are so persistent that they keep on coming back no matter what you do.

One of the more recent Mac malware that users have encountered is the TechFunctionSearch. There is not much information about it online, making Mac users unable to get more information regarding its nature and the removal process. When users get this error, they don’t notice anything weird with their computer, except for the notification message that keeps on popping up all the time.

If you’re being pestered by TechFunctionSearch on Mac, this article should give you all the information you need to deal with this malware. We’ll discuss what dangers TechFunctionSearch on your Mac and what you can do to completely remove it from your computer.

What is TechFunctionSearch?

TechFunctionSearch is a part of the adware family that is usually bundled with legitimate apps. It usually comes installed with the ForBrowser, an application that claims to enhance your internet connection speed and improve browsing experience. However, it is categorized by security programs as a potentially unwanted program or PUP that affects mainly the user’s default browser — Safari, Chrome, Firefox, or other browsers.

ForBrowser installs a new extension to the affected browser with unusually high privileges. It has access to all the information you type into the webpages you visit, including passwords, credit card details, email addresses, login information, and others. This virus circumvents the authorization process and gets installed without the approval of the user. Permissions are never asked so the stealthy installation of this browser already entails a security issue.

How to Tell You Have TechFunctionSearch?

Users will never notice that there is something wrong with the browser unless he or she intentionally checks the extensions installed on the browser, particularly the list of privileges there. In some cases, the virus overhauls the custom web surfing settings to drive more traffic to one or more of its affiliates. The default homepage and search engine are changed to a different URL and these changes cannot be reversed manually because the virus runs a script to make these changes again and again. The goal would be to force the user to visit the URL every time the user opens the browser or tries to search something online.

Aside from these browser changes, users that are affected by this virus are bombarded with ads whenever the infected browser is open. Most of the ads are even labeled with “Ads by ForBrowser”. Users will find in-text links, coupons, comparisons, and other suspicious ads spilled all over the webpages. When you see these annoying ads, it should give you a red flag about the presence of adware.

However, the ForBrowser virus is quite difficult to get rid of because it installs its components all over the system. TechFunctionSearch is just one of the components of the ForBrowser virus, along with TechSignalSearch, SearchRange, and others. To completely remove the virus, you should remove all these components first before uninstalling the ForBrowser.

Is TechFunctionSearch a Virus?

TechFunctionSearch is a component of the ForBrowser virus, making it malicious as well. Users that are infected with the virus will often come across this notification:

Do you want the application “TechFunctionSearch” to accept incoming network connections? 

The message keeps popping up no matter how many times the user closes the dialog, which has caused users no little annoyance to the affected Mac users. When you get this notification, this means that the TechFunctionSearch component of the ForBrowser virus is at work.
