UpgradeSample is macOS malware that stems from the notorious Adload strain

Originating from the Adload malware family, it is notable for its durability and ability to evade detection by conventional security tools. It is commonly spread through malicious ads, fake software updates, and pirated software, with a particular notoriety for being disguised as deceptive Flash Player updates.
Once installed on a Mac, UpgradeSample can perform various harmful activities. These activities include stealing personal information, displaying intrusive advertisements, and redirecting internet searches. Additionally, it has the ability to introduce additional malware into the infected system, increasing the overall threat.
This article explores the workings of the UpgradeSample virus, its unique characteristics, and the signs that indicate an infection. If your system becomes infected, it is vital to take immediate action to protect your device from further malware attacks and to maintain the privacy and security of your computer.

The Adload malware family, which specifically targets Mac computers, includes numerous variants like BinaryAccessibility or BrowserQuest. This malware family is widespread due to its effective distribution methods. One of the main ways it spreads is through counterfeit Adobe Flash Player installers, often found on untrustworthy websites or received via email attachments.
These installers are disguised as genuine Adobe software, even though Adobe has discontinued Flash Player. Therefore, any prompts to download Flash Player are misleading and deceptive.
Another common method for the spread of the UpgradeSample virus is through torrents and cracked software. This is how it typically works:
- Torrents facilitate peer-to-peer file sharing, where users directly exchange files.
- Cracked software involves illegal modifications that bypass security and licensing restrictions.
The risk of encountering malware significantly increases when users download these cracked versions, especially if they ignore security software warnings.
To protect against malware like UpgradeSample, it is important to download software only from reliable sources and be cautious of unexpected emails or messages with links or attachments. Using anti-malware software on Macs, keeping all software and operating systems updated, and being alert to unusual browser activities like new extensions, pop-ups, and redirections are essential defensive strategies. Recognizing these signs and responding promptly can greatly enhance your digital security.
Malware's capabilities
UpgradeSample is often categorized as adware because it displays advertisements in the browser or through other means. However, it is more than just a bothersome program; it can perform actions that typical adware cannot, which is why security experts and programs often label it as malware.
The main aim of the UpgradeSample virus is to show advertisements and generate pay-per-click revenue. It also has several additional capabilities that support its malicious activities. For instance, it uses AppleScript to completely bypass built-in Mac defenses like XProtect and Gatekeeper. This makes it essential to have extra security measures in place to protect your system.
The UpgradeSample virus installs itself on Safari or other browsers by gaining permissions granted by the user during installation. Once installed, it immediately takes control of the user's browsing sessions. If the user attempts to remove the app, they might find the extension grayed out in the settings menu, making it difficult to uninstall. Meanwhile, the app can collect various personal information from users without their knowledge or consent, posing a significant risk to privacy.
How to remove the virus?
UpgradeSample is especially challenging to remove because it operates with elevated permissions on the system. It not only drops multiple files but also creates new profiles and login items. Using built-in AppleScript, the malware can completely bypass Mac's built-in defense systems and continue functioning even if the main app or extension is removed.
For these reasons, it is recommended to automatically terminate the infection using Malwarebytes or SpyHunter 5Combo Cleaner security software. Regardless of the method you choose to delete it, it is also advisable to clear your web browser caches to prevent future issues.
If you prefer to try removing the infection manually, remember that the background process might interfere with your attempt. Therefore, open the Activity Monitor and shut down any related processes first.
Once installed, the malware operates background processes to carry out its tasks. To remove the main application, you should first shut down these processes using the Activity Monitor:
- Open Applications folder.
- Select Utilities.
- Double-click Activity Monitor.
- Here, look for suspicious processes and use the Force Quit command to shut them down.
- Go back to the Applications folder.
- Find the malicious entry and place it in Trash.
Login items are responsible for running the malicious app as soon as the computer boots up, whilst Profiles handle various account settings. The malware-related components should be deleted as follows:
- Go to Preferences and pick Accounts.
- Click Login items and delete everything suspicious.
- Next, pick System Preferences > Users & Groups.
- Find Profiles and remove unwanted profiles from the list.
Finally, you should remove Launch Daemons and any configuration data left by malware. Proceed as follows:
- Select Go > Go to Folder.
- Enter /Library/Application Support and click Go or press Enter.
- In the Application Support folder, look for any dubious entries and then delete them.
- Now enter /Library/LaunchAgents and /Library/LaunchDaemons folders the same way and delete all the related .plist files.
In the final stage of removing UpgradeSample, it is essential to address the changes made to your browsers. This involves deleting any extension components that the virus may have installed. However, sometimes direct removal of the extension may not be possible. In such cases, resetting the browser to its default settings is the best alternative. This step ensures that all modifications or additions made by the virus are entirely removed.
To clean cached files and other residual data left by the virus, you can use a maintenance tool like FortectIntego. This application automates the cleaning process, making it more efficient and thorough. If you prefer a manual approach, there are step-by-step instructions provided below.
These manual steps will guide you through clearing the cache and other temporary files that might still harbor remnants of the virus. Whether you opt for the automatic tool or the manual method, ensuring your browsers are completely clean is a crucial part of fully securing your system after an infection.

How to prevent from getting adware
Do not let government spy on you
The government has many issues in regards to tracking users' data and spying on citizens, so you should take this into consideration and learn more about shady information gathering practices. Avoid any unwanted government tracking or spying by going totally anonymous on the internet.
You can choose a different location when you go online and access any material you want without particular content restrictions. You can easily enjoy internet connection without any risks of being hacked by using Private Internet Access VPN.
Control the information that can be accessed by government any other unwanted party and surf online without being spied on. Even if you are not involved in illegal activities or trust your selection of services, platforms, be suspicious for your own security and take precautionary measures by using the VPN service.
Backup files for the later use, in case of the malware attack
Computer users can suffer from data losses due to cyber infections or their own faulty doings. Ransomware can encrypt and hold files hostage, while unforeseen power cuts might cause a loss of important documents. If you have proper up-to-date backups, you can easily recover after such an incident and get back to work. It is also equally important to update backups on a regular basis so that the newest information remains intact – you can set this process to be performed automatically.
When you have the previous version of every important document or project you can avoid frustration and breakdowns. It comes in handy when malware strikes out of nowhere. Use Data Recovery Pro for the data restoration process.
