What is SampleFormat mac virus?

SampleFormat mac virus can cause ad spam, changes to the browser and system

SampleFormatAdware infections for mac users can be much more devastating

SampleFormat is a mac virus that belongs to the Adload malware[1] family. It specifically targets mac machines and has both hijacking and adware[2] capabilities. Once it enters the system, it can cause an increased amount of commercial content, like pop-ups, banners, and redirects. It may also change the main browser settings, like the homepage, new tab address, and search engine.

Users are forced to browse only through selected channels which raises many user privacy and security concerns. The mac virus may also use rogue advertising networks that place ads leading to dangerous websites. People can end up on scam sites that try to trick them into providing personal information, downloading PUPs (potentially unwanted programs), and other malware.

Adload in detail

Adware developed to infect mac systems is much more aggressive than adware affecting Windows machines. Adload can fool Apple's security system XProtect,[3] so users notice that something is wrong only when it already lays its roots in the machine. By then, the malicious program has most likely gained permission to collect user data and make changes not only in the browsers but in the system as well.

Users can find the main file of SampleFormat virus in their “Applications” folder. We previously wrote about other versions of the Adload adware, like BasicTransaction, ElementForce, and EfficientRecord. If you look closely, they all have the same icon – a magnifying glass inside a green, teal, or grey background.

However, that does not mean that it is easy to eliminate. It scatters its malicious files across the machine disguised as normal system files. They can detect when someone is trying to eliminate the virus and create new files quickly. That is why it is best to avoid such intruders in the first place.

Distribution methods

One of the most common reasons for Adload infections, like SampleFormat, are fake Flash Player updates or installations. Threat actors use social engineering methods to trick people into thinking that their Flash Player is expired. They use deceptive messages to make people believe that if they do not install the latest version they will not be able to access media content.

Many people still do not know that Flash Player was discontinued in 2020 and replaced by HTML5. If you come across any website that is telling you otherwise, you should exit immediately. Such sites are often hidden on other shady pages so it is best to only visit websites that you know and trust. Do not click on random links and ads.

Another thing that you should be aware of is the danger of torrent websites,[4] and peer-to-peer file-sharing platforms. They are unregulated so they are the perfect breeding ground for malware. A lot of people are keen on installing “cracked” software[5] for free, however, you can never know if the program you want to install is safe and not secretly a Trojan or another type of malware.

Hackers also like to use software vulnerabilities so it is extremely important to keep your operating system and software up to date. Software developers regularly release security patches to prevent cybercriminals from exploiting them so you should install the patches as soon as they are released.

Removal of SampleFormat mac virus

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 which is a normal 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 various persistence techniques and drops many files across the system, making browser extension and application removal difficult.

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 SampleFormat 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 dubious entries and then delete them.
  • Now enter /Library/LaunchAgents and /Library/LaunchDaemons folders the same way and terminate all the related .plist files.Uninstall from Mac 2

The manual elimination process might not always result in full 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 SampleFormat 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.

You should eliminate 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.

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.
