Miner Virus on Mac – How Did I Get It and What Does It Do?
One scenario via which your computer could have become compromised by a Miner virus is likely done by the malware slithering via a compromised website. Some hackers compromise the downloads of sites and trick you into downloading the wrong file instead of the download you have googled. Usually such files often turn out to be cracks, patches, installers, portable apps and others. Another scenario is if the file gets sent to you via e-mail. These types of files are usually sent to you as a result of being attached to the e-mail and pretending to be legitimate e-mail attachments. Such attachments often seem as if they are invoices, receipts or important documents that have to be opened at any cost.
Whatever the case may be, once an infection with the miner in question occurs, the victim is enrolled in a cryptocurrency miner pool. This miner pool may initiate the so-called factorisation process that generates hashes. When enough hashes are gathered of the cryptocurrency, the award is credited to the hacker’s cryptocurrency wallet. A miner pool may contain a lot of computer so hackers tend to infect as many as they can, because they generate tokens faster.
The miner process may be conducted by a process actively running on your computer. This process may begin to perform a lot of different types of activities and these may slow down your Mac, make it stutter and even break it down entirely. What is not good in this situation is that the miner may also come with Trojan capabilities that may allow it to steal information from your Mac. Such can be:
- Keylogger that logs what you type.
- Microphone and camera control.
- Infostealer that can copy saved passwords and steal files.
- Read and write permissions over your files.
All of these components altogether plus the fact that if the miner remains on your Mac for longer, it may damage it’s components make the removal of this threat strongly advisable.

Step 1: Scan for Miner Virus with SpyHunter Anti-Malware Tool
Step 2: Clean any registries, created by Miner Virus on your computer.
The usually targeted registries of Windows machines are the following:
- HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run
- HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run
- HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunOnce

You can access them by opening the Windows registry editor and deleting any values, created by Miner Virus there. This can happen by following the steps underneath:
Tip: To find a virus-created value, you can right-click on it and click "Modify" to see which file it is set to run. If this is the virus file location, remove the value.Step 3: Find virus files created by Miner Virus on your PC.
1.For Windows 8, 8.1 and 10.
For Newer Windows Operating Systems
1: On your keyboard press + R and write explorer.exe in the Run text box and then click on the Ok button.
2: Click on your PC from the quick access bar. This is usually an icon with a monitor and its name is either “My Computer”, “My PC” or “This PC” or whatever you have named it.
3: Navigate to the search box in the top-right of your PC's screen and type “fileextension:” and after which type the file extension. If you are looking for malicious executables, an example may be "fileextension:exe". After doing that, leave a space and type the file name you believe the malware has created. Here is how it may appear if your file has been found:
N.B. We recommend to wait for the green loading bar in the navigation box to fill up in case the PC is looking for the file and hasn't found it yet.
2.For Windows XP, Vista, and 7.
For Older Windows Operating Systems
In older Windows OS's the conventional approach should be the effective one:
1: Click on the Start Menu icon (usually on your bottom-left) and then choose the Search preference.
2: After the search window appears, choose More Advanced Options from the search assistant box. Another way is by clicking on All Files and Folders.
3: After that type the name of the file you are looking for and click on the Search button. This might take some time after which results will appear. If you have found the malicious file, you may copy or open its location by right-clicking on it.
Now you should be able to discover any file on Windows as long as it is on your hard drive and is not concealed via special software.
