OperativeFraction is a potentially unwanted program designed to infect Mac users

OperativeFractionOperativeFraction is a potentially unwanted program that installs other apps without permission on Mac computers

OperativeFraction is one of many applications belonging to the Adload malware family that has been spreading around the internet via fake Flash Player installers or pirated software downloads. The infection, which exclusively targets Mac users, has some of the browser hijacking capabilities, as it changes new tab and homepage address without permission, appends, and extension to the web browser and then delivers sponsored links via search results. Besides, OperativeFraction will also make Google Chrome, Safari, Mozilla Firefox, or another web browser to push popups, in-text links, deals, banners, offers, and other intrusive advertisements.

While the functions of OperativeFraction might seem like those of a regular adware/browser hijacker, it is important to note that its delivery and operation methods are closely related to those of malware. Besides being delivered via fake Flash Player updates, it also establishes persistence on the system, preventing users from successful OperativeFraction uninstall. Also, some versions of the app are capable of harvesting sensitive information via the browser, such as banking details.

OperativeFraction belongs to a broad malware family designed for Mac systems. These potentially unwanted or borderline malicious programs use the same icon – green or teal color circle with a magnifying glass. Other members of the family include AccessibleBoost, BufferKey, SectionBrowser, ArchimedesLookup, DataQuest, and many others. Essentially, all these apps are exact copies of each other, they only use a different name. It is yet unknown who the developer behind OperativeFraction malware is.

As previously mentioned, one of the most prevalent features of the OperativeFraction virus is its distribution techniques. In most cases, users do not install the app deliberately but instead are tricked into doing so. Once installed, adware uses the built-in AppleScript in order to perform various system changes, e.g., establishes new login items or profiles. These modifications might result in difficulty when trying to remove OperativeFraction in a regular way.

Besides the invisible changes, OperativeFraction initiates system hijack that can be noticed right away. Some of the infection symptoms include:

  • New tab and homepage address of the web browser is set to an unknown provider (e.g., Safe Finder);
  • All search results are filled with sponsored links;
  • OperativeFraction extension installed on the web browser and can not be eliminated;
  • Unknown applications or browser extensions installed without permission.

In most cases, users who attempt to uninstall OperativeFraction extension from their browsers fail to do so, as various persistence mechanisms prevent them from doing so. However, this is not the only malicious trait of the add-on, as it can also read sensitive data that type in via the web browser – banking information, login credentials, and other details are no longer safe.

OperativeFraction virusOperativeFraction is a Mac virus that might harvest your personal information

Besides privacy issues, OperativeFraction hijack can also be extremely frustrating to deal with, as users who have the unwanted app installed on their systems will notice that popups, deals, offers, coupons, and other intrusive commercial content is present all over the web. Note that this can be blocked with the help of effective ad-blockers. While most of the OperativeFraction ads will provide relatively harmless content, some popups and redirects can lead to scam, phishing, or even malware-laden sites.

Finally, another good reason for OperativeFraction removal is the fact that it can be closely associated with Shlayer Trojan or another Mac malware. These malicious programs are designed to flood users' browsers with background connections (to generate revenue for cybercriminals) and install more unwanted applications without permission.

Thus, if you spotted a suspicious magnifying glass icon on your Mac, do not way and terminate it immediately. You can follow our guidelines below. If you can not uninstall OperativeFraction from your browser, you can reset it. For best results, we also recommend using Reimage Reimage Cleaner Intego – it will find and remove all the useless junk files from the system to boost its speed.

Mac system is secure as long as you do not let malicious software in

Some things that might seem simple are actually not. Security experts[2] are constantly reminding that Macs are relatively safe operating systems – as long as users are not tricked into letting malware or adware in. Indeed, in the study conducted by security researchers in early 2020, it was discovered that Mac malware is outpacing Windows malware when it comes to detection rate.[3]

As evident, Mac users are always asked to enter their AppleID every time they attempt to install an application from an unauthorized source, for example, a torrent site. However, many are keen on ignoring the built-in warnings and let the app get installed regardless. While in some cases, users deliberately avoid listening to security advice, others are simply tricked into letting malware in.

One of the main problems for Macs is fake updates – these can show up on many malicious websites and ask users to download and install a seemingly needed Flash Player update. However, what users are downloading is not a plugin update, but rather a malicious application instead.

OperativeFraction detectionDue to deceptive OperativeFraction operation and distribution techniques, the PUP is flagged by most security vendors

Uninstall OperativeFraction from your computer as soon as possible

Most of the adware programs are relatively harmless, as they do not establish persistence mechanisms on the system – they can be uninstalled by dragging the PUP to Trash. However, some apps are just way more difficult to eliminate in a regular way – and so can be the OperativeFraction removal.

If you want to attempt to remove OperativeFraction manually, you should check the following locations on your system and eliminate all the suspicious entries:

  • System Preferences > Accounts> Login Items
  • System Preferences > Users&Groups > Profiles
  • ~/Library/LaunchAgents
  • ~/Library/Application Support
  • ~/Library/LaunchDaemons

Since the OperativeFraction virus installs an extension on Safari, Google Chrome, or Mozilla Firefox, you should also reset the browser to get rid of all the malicious plugins. However, instead of worrying about how to eliminate this persistent malware by yourself, you could instead use a powerful anti-malware solution and perform a full system scan – this would find all the unwanted software/malware and terminate it automatically.

Choose a proper web browser and improve your safety with a VPN tool

Online spying has got momentum in recent years and people are getting more and more interested in how to protect their privacy online. One of the basic means to add a layer of security – choose the most private and secure web browser. Although web browsers can't grant a full privacy protection and security, some of them are much better at sandboxing, HTTPS upgrading, active content blocking, tracking blocking, phishing protection, and similar privacy-oriented features. However, if you want true anonymity, we suggest you employ a powerful Private Internet Access VPN – it can encrypt all the traffic that comes and goes out of your computer, preventing tracking completely.


Recover files after data-affecting malware attacks

While much of the data can be accidentally deleted due to various reasons, malware is one of the main culprits that can cause loss of pictures, documents, videos, and other important files. More serious malware infections lead to significant data loss when your documents, system files, and images get encrypted. In particular, ransomware is is a type of malware that focuses on such functions, so your files become useless without an ability to access them.

Even though there is little to no possibility to recover after file-locking threats, some applications have features for data recovery in the system. In some cases, Data Recovery Pro can also help to recover at least some portion of your data after data-locking virus infection or general cyber infection.
