App_assistant is an advertising application that spams Mac browsers with aggressive web ads and seeks to redirect users to sponsored sites. App_assistant is known as a browser hijacker and once it gets integrated with your main browser, it changes its settings without asking for permission. Some users consider this software potentially dangerous and even call it a virus, but it must be noted that a browser hijacker poses no real threat to the computers on which it is mounted.

The App_assistant will damage your computer Malware message

As opposed to Trojans, Ransomware, Spyware and other online viruses, most browser hijackers are primarily designed to generate revenue for their developers by showing paid advertisements and promoting specific sites on the users screen which pay commissions to anyone who promotes them and drags traffic to them. Briefly, it’s probably not necessary to be too concerned about having an application like App_assistant in your Safari, Firefox, or other web browsers. However, there are certain aspects that might cause such a program to become potentially unsafe in the long term, so the best course of action is to remove it for the sake of your Mac’s future safety.

App_assistant for Mac

App_assistant for Mac is a browser hijacking application that can be set up in popular Mac browsers and display various sponsored ads through them. In addition to the ad-generation, App_assistant for Mac can have the browser’s search engine, toolbar or homepage altered. These changes allow the browser hijacker to place various sponsored advertisements on your screen during your web browsing sessions and to automatically redirect you to websites that contain promotions that might be of interest to you.

Unfortunately, it is not a good idea to trust every pop-up, banner, or redirect link that gets displayed on your screen by the browser hijacker because you can never be sure that if you click on it, it would lead you to the exact website that it promotes. You can eventually be redirected to a page that contains completely different content than what you were initially interested in or to a website that distributes malware and viruses such as Ransomware and Trojans.

Remove “App_assistant will damage your computer” from Mac

The following instructions will allow you to remove “App_assistant will damage your computer” in two ways:

  • The manual instructions will allow you to remove it on your own by downloading 2 software suites which will show you the folders the threat is located in. Installing, scanning, and deleting everything will require 1-2 hours of your time, depending on your speed and the threat itself.
    Note: If “App_assistant” has an in-built ability to restore itself on a restart, the manual steps will not prevent that. We recommend automatic removal.
  •  Download SpyHunter for Mac (one of the apps used in the manual instructions), scan with it, and if you decide to use the program, it will likely require about 15-20 minutes. This, however, requires an active subscription for SpyHunter, which means either using the trial version or purchasing the software.

Removal instructions:
1. Download EtreCheck from the Appstore and scan for any “App_assistant” unsigned files. Delete them. (You can skip this step altogether and download and scan with SpyHunter instead if you don’t want to double-check things).
2. Download and install Spyhunter for Mac. Scan for any malicious files.
3. The app will show you which files are infected. Either use SpyHunter to delete them for you (the automatic removal) or do it manually, which means tracking down each detected location by yourself and deleting the file.
4. In most cases start with /private/var/root/Library/Application Support/.”App_assistant”/”App_assistant”
5. In Finder press Shift+Command+G to open the Find window.
6. Search for the /var directory. Then proceed and look for the /root folder inside.
7. It will most likely be locked and you will need additional permissions to meddle with it.
8. Press command+I and scroll to sharing and permissions. Add your user name to permissions.
9. Now you should be able to access the /root folder and proceed and locate the /Library folder inside it. Proceed to do the same until you are inside the /Application Support folder.
