MemoryFunction mac virus Removal Guide
What is MemoryFunction mac virus?
MemoryFunction mac virus can change the settings of your browser and cause ad spam
MemoryFunction mac virus might install PUPs or malware in the background
MemoryFunction is a virus that specifically targets Mac machines because it belongs to the Adload malware family. It has both hijacking and adware capabilities. It can change the main browser settings, like the homepage, new tab address, and search engine. Users may also start to experience an increased amount of commercial content, like pop-ups, banners, and redirects.
What is more, adware created for Macs is much more aggressive than those designed to infect Windows operating systems. It can do much more, like install PUPs (potentially unwanted programs) or even malware automatically, without the users' knowledge, or scatter its files in various folders to make it challenging to locate and eliminate manually.
Most do not notice the intruder until it has already started making changes because it can bypass Apple's own security system XProtect. People can find the main file of the virus in their “Applications” folder. All Adload viruses have the same icon – a magnifying glass inside a green, teal, or grey circle background.
However, it is not enough to put this file into the trash and move on. The adware uses various evasion techniques to prevent people from removing it easily. It scatters malicious files across the machine disguised as normal system files. That is why it is best to avoid such intruders in the first place.
|TYPE||Adware, browser hijacker, mac virus|
|SYMPTOMS||Changed homepage and new tab address, a different search engine; redirects to shady websites|
|DISTRIBUTION||Fake software updates, deceptive ads, software installations from peer-to-peer file-sharing platforms|
|DANGERS||Altered search results can lead to dangerous websites; pop-up ads might be promoting scams; the virus can install other PUPs or even malware in the background|
|ELIMINATION||Eliminating this Mac virus manually can be complicated if you do not have experience. The most effective way to remove it is with a professional security tool that can scan your system to delete every related file|
|FURTHER STEPS||ReimageIntego should be used to completely wipe out any data left and fix the remaining damage|
Most of the time, MemoryFunction, and other Adload viruses like WheelInstant, IndexerSource, and PositiveAnalyzer are installed by users unknowingly. The virus is often disguised using social engineering techniques to be something else, like a software update.
For example, even though Flash Player was discontinued in 2020 and replaced by HTML5, users still fall for prompts that say they need to update their Flash Player to access some kind of content on the website. If you see any such messages, they are definitely fake.
Another common way Mac adware is spread is through “cracked” software installations from peer-to-peer file-sharing platforms and torrent pages. Such platforms are the perfect breeding ground for all kinds of malware. Even though it might get costly to pay for software licenses, you may save in the long run by keeping your system running smoothly.
The obvious thing to do would be to implement some security habits to prevent this from happening again. And that would be not trusting external sources with updates – always go to the primary source to find out if you really need an update. Do not pay attention to random pop-ups and redirects. Use the official app store for software downloads.
One of the most important things to do that many do not realize is keeping your operating system and software updated. Hackers like to use software vulnerabilities to deliver their malicious programs. Developers release security patches regularly to fix this so install them as soon as they come out.
Remove the MemoryFunction mac virus
MemoryFunction mac virus creators use various distribution tactics
Manual removal may be a race against time. With launch agents, daemons, and cronjobs, it can sometimes take several attempts to beat all of these before one of them manages to re-write deleted components back. You should not do this yourself unless you know what you are doing and what kind of files you need to delete.
Some of the files can have a .plist extension, a standard settings' file, also known as a “properties file,” used by macOS applications. It contains properties and configuration settings for various programs. The app also uses different persistence techniques and drops many files across the system, complicating browser extension and application removal.
To keep your mind at peace, we recommend using professional anti-malware tools SpyHunter 5Combo Cleaner or Malwarebytes, which can detect unwanted programs and eradicate them. You also do not know if the virus installed any additional malicious programs, so this is the safest way to ensure the system is clean.
If you still want to try and delete it manually, proceed with these steps:
- Open Applications folder
- Select Utilities
- Double-click Activity Monitor
- Here, look for suspicious processes related to adware and use Force Quit command to shut them down
- Go back to the Applications folder
- Find MemoryFunction in the list and move it to Trash
If you are unable to shut down the related processes or can't move the app to Trash, you should look for malicious profiles and login items:
- Go to Preferences and select Accounts
- Click Login items and delete everything suspicious
- Next, pick System Preferences > Users & Groups
- Find Profiles and remove unwanted profiles from the list
There are likely to be more .plist files hiding in the following locations – delete them all:
- Select Go > Go to Folder.
- Enter /Library/Application Support and click Go or press Enter.
- In the Application Support folder, look for any suspicious entries and then delete them.
- Now enter /Library/LaunchAgents and /Library/LaunchDaemons folders the same way and terminate all the related .plist files.
The manual elimination process might not always result in total virus removal. Therefore, we still strongly suggest you perform a scan with security software.
Remove the browser extension
An extension to your browser is also added by MemoryFunction that starts performing all sorts of unwanted tasks. It possibly collects sensitive data and sends it to tracking servers. Some of the data that could be exposed is – IP address, user name, macOS version, browser versions, computer ID, items in the “Applications” folder, a list of agents, daemons, and system configuration profiles.
It would help if you removed the add-on as soon as possible after the dangerous files are eliminated from your system. You can delete cookies and cache automatically with the help of ReimageIntego. It will also fix any damaged files and system errors, so you should notice an improvement in the machine's performance.
If you prefer doing this yourself without additional help, here are the instructions. You will find guides for Google Chrome and Mozilla Firefox at the bottom of this article:
- Click Safari > Preferences…
- In the new window, pick Extensions.
- Select the unwanted extension and select Uninstall.
Cookies and website data:
- Click Safari > Clear History…
- From the drop-down menu under Clear, pick all history.
- Confirm with Clear History.
The simplest and quickest solution to this is completely resetting Safari:
- Click Safari > Preferences…
- Go to Advanced tab.
- Tick the Show Develop menu in the menu bar.
- From the menu bar, click Develop, and then select Empty Caches.

How to prevent from getting adware
Stream videos without limitations, no matter where you are
There are multiple parties that could find out almost anything about you by checking your online activity. While this is highly unlikely, advertisers and tech companies are constantly tracking you online. The first step to privacy should be a secure browser that focuses on tracker reduction to a minimum.
Even if you employ a secure browser, you will not be able to access websites that are restricted due to local government laws or other reasons. In other words, you may not be able to stream Disney+ or US-based Netflix in some countries. To bypass these restrictions, you can employ a powerful Private Internet Access VPN, which provides dedicated servers for torrenting and streaming, not slowing you down in the process.
Data backups are important – recover your lost files
Ransomware is one of the biggest threats to personal data. Once it is executed on a machine, it launches a sophisticated encryption algorithm that locks all your files, although it does not destroy them. The most common misconception is that anti-malware software can return files to their previous states. This is not true, however, and data remains locked after the malicious payload is deleted.
While regular data backups are the only secure method to recover your files after a ransomware attack, tools such as Data Recovery Pro can also be effective and restore at least some of your lost data.
