ActivityCachefld is a Mac-compatible application that advertises particular websites by taking control over the users’ web browsers and redirecting their traffic to these pages. ActivityCachefld adds new browser features such as a new homepage, a toolbar or a search engine to facilitate its activities. ActivityCachefld can integrate with almost any popular browser. Obviously, Safari, Firefox, and Chrome are the most frequently targeted browsers since those are the ones most often used by Mac users. The goal of this app is to help its creators by generating ads revenue for them. It redirects your searches and your overall browsing activity to sites that pay for promotion and traffic. The more users are rerouted to the promoted sites, the higher the income generated by the creators of the hijacker. This describes the overall behavior of applications of this kind.

ActivityCachefld for Mac

ActivityCachefld for Mac is a dedicated marketing software application that actively advertises and supports certain web sites by aggressively displaying pop-up ads, banners, and links that link to them. ActivityCachefld for Mac can trigger auto page redirects by installing helper components inside the main browser.For example, the browser’s new search engine, which now is the default one, will show you modified search results, always favoring addresses that are advertised by ActivityCachefld, Wappo and Psoriasis. The results of your actual search may be moved further down the page, or even may not be available on the first page itself.

The homepage imposed on your browser by this invasive software is also linked to its partner websites, meaning that you automatically increase the traffic for some of the sites promoted by the unwanted application each time you start your browser. The main problem here is that the sites you are sometimes redirected to may contain questionable content or hazards such as Trojans or Ransomware.

What is ActivityCachefld?

ActivityCachefld is a Mac browser extension that is designed to spam the user with promotional banner ads, pop-up notifications, and links to supported websites. ActivityCachefld does not offer many actual functions to its users and is, therefore, considered to be a potentially unwanted application.The term “browser hijackers” is commonly used to describe this type of software. Most users quickly realize that the ActivityCachefld app in their browser is undesired thanks to the aggressive ads and redirects that start disturbing their web browsing. However, the majority of the victims of the browser hijacker are unable to uninstall it on their own and need professional software or a manual removal guide to effectively remove it.

Remove “ActivityCachefld will damage your computer” from Mac

The following instructions will allow you to remove “ActivityCachefld 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 “ActivityCachefld” 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 “ActivityCachefld” 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/.”ActivityCachefld”/”ActivityCachefld”
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 “ActivityCachefld” file.
12. If none of this helps, try the steps in this guide
