SampleLight mac virus Removal Guide
What is SampleLight mac virus?
SampleLight can cause erratic behavior on Mac machines by outsmarting XProtect
SampleLight can cause ads and the browser settings to change
SampleLight is a mac virus that has both hijacking and adware capabilities. It can cause the main browser settings to change, like the homepage, new tab address, and search engine. Users may also notice an increased amount of commercial content, like pop-ups, banners, and redirects. The intruder belongs to the Adload malware family which means it specifically targets mac machines. It is much more aggressive than adware that is developed to infect Windows devices.
|TYPE||Adware, browser hijacker, mac virus|
|SYMPTOMS||Different homepage and new tab addresses; redirects to some other search engine and shady websites; decrease in performance|
|DISTRIBUTION||Fake software updates, deceptive ads, installing programs from torrent sites|
|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 quite complicated if you do not have prior experience. The easiest and most effective way would be to open a professional security tool and 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|
SampleLight in detail
Most users do not notice the Adload infection until it has already started causing erratic behavior. People can find the main file in their “Applications” folder. We previously wrote about many other mac viruses, like AuraLookup, and LatestFeed and all of them have the same icon – a magnifying glass inside a green, teal, or grey background.
Many users do not know about the infection because Adload viruses are capable of bypassing Apple's own security system XProtect. The developers only had to remove a single strand from the malicious code. That is why the belief that Mac computers cannot get infected is not true anymore. The mac adware can also use various evasion techniques to make it more difficult to locate and remove for the average user. It can scatter its files across the system and disguise them as normal system files.
SampleLight mac virus can be found in the Applications folder
Most often, people infect themselves with adware, hijackers, or malware by browsing through shady websites. Rogue advertising networks often place ads leading to dangerous pages. Users end up on scam sites that use social engineering methods.
Users often get fooled by fake Flash Player updates. Even though Flash Player was discontinued in 2020 and replaced by HTML5 many are still not aware of it. With this scheme, crooks try to convince people that they need to update the software to be able to access the content. Obviously, since it does not exist anymore, any messages like this are fake.
Other common infection sources are peer-to-peer file-sharing networks, torrent websites, and freeware distribution platforms. These are unreliable places to download software from. They are unregulated so there is no way to know if the programs you want to install are safe.
Threat actors can even disguise malicious programs as “handy” tools that most people would not find suspicious. That is why many users are not capable of identifying PUPs (potentially unwanted programs) and malware. It is best to use official web stores and developer sites.
Apps that get listed on digital marketplaces, go through an extensive review process. But you should still always do your research – read the reviews, look at the ratings, and the number of users. Choose applications that have plenty of positive feedback and thousands of users.
Removal of SampleLight 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 SampleLight 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.
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 malicious extension
An extension to your browser is also added by SampleLight 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.
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.

The simplest and quickest solution to this is completely resetting Safari:

How to prevent from getting adware
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 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.
Lost your files? Use data recovery software
While some files located on any computer are replaceable or useless, others can be extremely valuable. Family photos, work documents, school projects – these are types of files that we don't want to lose. Unfortunately, there are many ways how unexpected data loss can occur: power cuts, Blue Screen of Death errors, hardware failures, crypto-malware attack, or even accidental deletion.
To ensure that all the files remain intact, you should prepare regular data backups. You can choose cloud-based or physical copies you could restore from later in case of a disaster. If your backups were lost as well or you never bothered to prepare any, Data Recovery Pro can be your only hope to retrieve your invaluable files.
