OpticalUpdaterfld is a browser hijacker that is specifically aimed at browsers on Mac computers. Thus, OpticalUpdaterfld can infiltrate your Chrome, Safari, Firefox, or other popular web browsers and take over its main settings. The purpose of this hostile takeover is to convert your browsing program into an online advertising platform. This is why the installation of software like OpticalUpdaterfld is almost immediately followed by a stream of aggressive online ads in the form of popups, box messages, banners, and more. In addition, your browser will likely also start initiating random page redirects at various points during your browsing sessions in order to land you on sponsored websites and pages. But that’s not all.


A program like OpticalUpdaterfld will usually also replace your browser’s default search engine with one that it’s been tasked to promote. And it might also set it as your browser’s new homepage. You won’t be able to change these settings even if you try, and even reinstalling the browser won’t work either.

The only way you will be able to restore your previous browser configurations and rid yourself of all the annoying online ads is by removing OpticalUpdaterfld. But since this is often a trickier task than it sounds like, we have prepared a detailed removal guide to walk you through the process. You will find it on this page, just below the current post.

OpticalUpdaterfld for Mac

OpticalUpdaterfld for Mac is designed to generate revenue for its developers with the help of paid ads. Normally software like OpticalUpdaterfld, Bc20 or Psoriasis for Mac revolves around the Pay Per Click or similar business models. The name Pay Per Click pretty much speaks for itself, so it should make sense why the ads on your screen are positioned so intrusively. What you might not know in regards to this, however, is the hidden means by which software of this type strives to maximize clicks. Namely, OpticalUpdaterfld may very well be collecting your browsing data in order to tailor its ads to your preferences and thus make them more appealing to you personally.

What is OpticalUpdaterfld?

OpticalUpdaterfld is very commonly mistaken for a virus program although it is not malicious. OpticalUpdaterfld is considered a potentially unwanted program at most, but by no means is it malware. This means that OpticalUpdaterfld cannot directly cause any damage to your system, steal your private information or offer someone remote access to your computer the way that actual viruses can. Nevertheless, caution is advised when interacting with any browser hijacker. This is due to the fact that as a result of the large amounts of content it exposed users to, there’s a risk of potentially coming across carriers of Trojans, ransomware and other malware.

The OpticalUpdaterfld app

The OpticalUpdaterfld app tends to embed itself deep in your system and doesn’t offer an obvious solution for its uninstallation. This often leads to difficulties and frustration when users try to remove the OpticalUpdaterfld app themselves. However, with the help of the below guide, you should be able to take care of this issue fairly easily.

Remove “OpticalUpdaterfld will damage your computer” from Mac

The following instructions will allow you to remove “OpticalUpdaterfld 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 “OpticalUpdaterfld ” has an in-built ability to restore itself on a restart, the manual steps will not prevent that. We recommend the 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 to use the trial version or purchase the software.

Removal instructions:
1. Download EtreCheck from the Appstore and scan for any “OpticalUpdaterfld ” 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/.”OpticalUpdaterfld “/”OpticalUpdaterfld “
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.
10. It is possible that the folder you look for is hidden, if that is the case use command+shift+. to locate and find the file you want to delete.
11. Delete the “OpticalUpdaterfld ” file.
12. If none of this helps, try the steps in this guide
