"Someone please help me as my Mac has been infected by a Trojan virus! Do I need an antivirus for Mac or can I do Mac virus clean up with some native features?"
This is one of the many queries of Mac users about getting their system infected by a virus. While Mac systems are extremely secure, they are not foolproof and can be comprised of a severe security attack. In a situation like this, you can do a virus check on Mac to know the present security status of the system. Later, you need to perform Mac virus removal by choosing the right technique. If left unchecked, it can cause permanent damage to your data and the system storage itself. In this guide on how to get rid of viruses on Mac, we will help you clean your system in different ways.
A lot of Mac users believe that their systems can never be infected by a virus – which is a common misconception. Just like every other operating system (like Windows), macOS also has its vulnerabilities. Although the newly released macOS versions are more secure than ever, they can still be infected by malware.
For instance, in 2012, Flashback malware infected more than 600,000 Mac systems worldwide. More recently, in 2017 and 2018, Proton and Mami virus hit thousands of Mac computers. Ideally, the impact would depend on the intensity of the security attack and the vulnerability of the macOS. In 2015, BitDefender analysts released a report that stated macOS X has more vulnerabilities than all the recent Windows versions combined.
In a nutshell, macOS can be infected by a virus attack. Most of these attacks are caused online or through a connected medium like USB or Bluetooth.
Before we discuss how to remove virus from Mac, it is important to cover the basics. Essentially, you should do a virus check on Mac regularly to make sure if your system is infected by malware or not. To do this, you can simply use a dedicated Firewall or antivirus tool on your Mac and enable the real-time scan. In this way, it will keep scanning your Mac system in the background and would let you know as soon as any virus is detected.
Apart from that, the following are some of the telltale signs that are related to the presence of unwanted malware on the system.
Since the native feature does not provide a direct solution to detect malicious entities, you can try an alternative. There are several third-party applications like BitDefender, Malwarebytes, ClamXAV, etc. that can help you scan your Mac instantly.
If your Mac is showing either of the above-listed signs or a third-party tool has detected a virus on it, then you need to be alert. Here are some suggested techniques on how to get rid of malware on Mac that you can also apply.
First things first – you need to make sure that no malicious application should be running on your Mac. To do this, you can take the assistance of Mac's Activity Monitor and force quit the application.
Quitting any malicious app from the system is not enough. If you want to delete the virus on Mac, then consider uninstalling the application altogether.
Apart from applications, a malicious entity can be present in any folder as well. Also, if one file has been infected, then the malware can propagate to other sources too. To fix this and learn how to get rid of the virus on the Mac, make the hard choice of deleting the infected content.
A lot of people don't realize it, but most of the security threats origin from one or another online source. Unreliable browser plugins are considered as one of the common sources of these malware attacks. Therefore, to learn how to check the virus on the Mac, have a look at the installed extensions and get rid of any suspicious entity.
Apart from extensions, malware can enter your Mac in other forms as well. For instance, it can be disguised as a cache, temp, or log file as well. To do a Mac virus clean up, make sure that you also remove all the existing data from your browser. While this will also wipe its saved account data and cache, it will also make your system more secure.
If you are not able to do an entire Mac virus removal, then consider escaping it instead. To do this, you can just create a new user profile on your Mac. Though, make sure that you delete all the login items in advance so that the virus will not have the needed permissions. Here's how to get rid of the virus on Mac by creating a new profile.

If none of the above-listed solutions can delete the virus on Mac, then consider wiping its storage entirely. Needless to say, this will delete all the saved data from your Mac's hard drive. Though, it will also get rid of the existing malware in the process as well. To learn how to remove virus from Mac by clearing its disk, follow these steps:

There are several reliable antivirus applications for Mac like Kaspersky, BitDefender, Malwarebytes, ClamXAV, and so on. These applications will let you perform an in-depth scan of the system's storage and can even clean your Mac from malicious files as well.
