Most Mac users used to believe that the macOS is safe from viruses and malware that commonly affect other operating systems. However, we now know that this is not true. Virus attacks targeting macOS have been reported over the years, proving that Apple products aren’t immune to malicious software infections.
Some of these attacks included:
Even Macs Need Antivirus Protection. PCs get viruses; Macs don’t. You saw it on TV, so you know. There are several steps you can take to get rid of a virus on an infected Mac computer. Here's a guide with methods and advice for every Mac user.
The Flashback malware, which affected more than 600,000 Macs in 2012.
The OSX/KitM.A virus, which took screenshots of the affected computer’s desktop and uploaded them to several websites.
The OSX.Proton in 2017, which took advantage of a vulnerability in the macOS Keychain app.
Last year’s snooping malware called OSX/Mami, which spied on the infected computer’s internet traffic.
These attacks prove that even macOS can also be vulnerable to phishing scams, trojan horses, and online fraud. In fact, some researchers have specially created a malware to prove that macOS is not omnipotent. In 2015, researchers created Thunderstrike 2, a firmware worm that is almost impossible to detect and get rid of. The malware only needs a few seconds to attack the extensible firmware interface of the infected Mac during boot up, and the device will remain infected even if the hard drive is wiped clean and the macOS is reinstalled.

Running an antivirus software is not enough to get rid of these pesky viruses and malware. You need to do a deep clean of your computer to make sure that all malicious software is completely removed from your system. Some Mac users go as far as resetting their computer to their factory settings to get rid of the virus.
Will a Factory Reset Remove a Virus?
This is a question Mac users have been wondering about for a long time.
Can a virus survive a factory reset on Mac? The answer is Yes and No. It depends on what virus or malware your Mac is infected with.
Common malware and viruses can be easily removed by antivirus applications. Some are harder to deal with, such as bootkits which infect the boot sectors of your Mac and viruses that target your Mac’s Extensible Firmware Interface or EFI (equivalent to BIOS in Windows OS). There are also viruses that infect computer-related hardware such as routers, phones, and printers, which are quick to spread and difficult to get rid of completely.
Doing a factory reset might seem like a good idea if your Mac is infected. But even this does not guarantee that your system will be 100% clean. There are several viruses that are so persistent that they can survive a factory reset and reformat of the drive.
For example, some Mac users reported being plagued by the MyCouponize adware on Safari even though the device has been reset. Others continue to experience performance issues even after purging the malicious software from their Macs. This is a testament to how viruses and malware are becoming more resilient and more intelligent over the years.
So if you’re thinking that resetting your Mac will completely get remove the virus on your computer, then you’re in for a surprise. Resetting your Mac to its factory settings might get rid of those uncomplicated viruses, but it won’t work on highly complex ones. So what do you do when you suspect your Mac to be infected by malicious software?
How to Remove Virus or Malware From Mac
Some of the symptoms of a computer virus or malware infection are:
Slow startup and sluggish performance
Insufficient storage space
Unexpected pop-up ads or messages
Heavy RAM and hard drive activity even during inactivity
Missing files
App crashes and error messages
Hijacked emails
Too much network activity
Any of these signs could indicate a virus or malware infection. If you suspect your Mac is infected, here are the steps that you can do:
Step 1: Disconnect Your Mac From Your Home or Office Network.
Remove all connected computer peripherals such as mouse, USB keyboard, printer, speakers, and flash drives. This is to prevent the spread of the infection in case you were hit by a hardware-related virus.
Step 2: Uninstall Recently Installed Software.
If you noticed your Mac’s behavior changing after downloading and installing new software, such as an app, extension, or add-on on your computer, then it is possible that the software you downloaded is the root of the infection. Uninstall it immediately and delete all folders associated with the software from the Library.
Step 3: Run a Scan.
Scan your computer for any infection using your antivirus software. Make sure that your antivirus is updated, so that you’ll be able to scan new threats. Follow the software’s instruction to resolve any infections found and get rid of the infected files. Don’t forget to empty your Trash.
Step 4: Clean Up Your Mac.
Use Outbyte MacRepair to remove all junk files from your Mac, particularly the infected files that you’ve just deleted.
Step 5: Update Your macOS.
One of the reasons why system updates are crucial is that they usually include security or software updates that help protect your macOS against malicious attacks. Skipping these updates means not taking advantage of the security tools that should add an extra layer of protection to your Mac.

Click on the Apple logo in the upper-left portion of the screen.
Choose App Store from the dropdown menu.
Click on the Updates tab, then install all available updates.
Type in your Apple ID and password to proceed with the installation.
You can also configure your Mac to automatically install the available updates so you don’t have to them manually every time. To do this:
Launch App Store once again, then click App Store from the top menu.
Choose Preferences to open the settings window.
Under Automatically check for updates, tick off the following options:
Download newly available updates in the background
Install app updates
Install macOS updates
Install system data files and security updates
Now, you don’t ever have to check the App Store again for new updates because they will be automatically downloaded in the background and installed overnight.
Step 6: Reset Your Mac and Wipe the Drive.
If the above steps do not work, resetting your Mac is your last option. However, a simple reset is not enough. You need to wipe out your drive completely to make sure no rootkits or bootkits are left lurking in your device.
Follow these steps to reset your Mac and wipe your hard drive clean:
Sign out of everything: iCloud, Messages, iTunes, and other Apple services.
Restart your system and once you hear the startup sound, press the Command + R shortcut to boot into macOS Recovery.
Choose Disk Utility, then click Continue.
Select the hard drive where your macOS is installed.
Hit the Erase button at the top of the Disk Utility menu.
Choose your hard drive format: Mac OS Extended (Journaled) or APFS.
Select GUID Partition Map under Scheme, then click Erase.
Quit Disk Utility and re-install a fresh copy of your Mac operating system.
Once you have installed a new version of your macOS, don’t copy over your files from your backup immediately. Scan them first for viruses and malware because they might also be infected. The same goes for apps and files stored in the cloud.
Summary
Not all viruses and malware are created equal. Some can easily be removed by deleting the infected files or apps, while others need to be dealt with using an antivirus software. Those that are tough to crack can be removed by resetting the computer to its factory settings.
However, there are special viruses and malware that can’t be eliminated even after a factory reset. If this is the case, you need to wipe your hard drive clean before re-installing your macOS. You can also read implement some preventive measures to protect your Mac from malware and other malicious elements.

How to Clean Mac Hard Drive Manually
If you never performed an automatic or manual system cleaning — it means that your Mac has been collecting unnecessary files and clutter for years. You can quickly clean up your Mac with these easy steps.
1. Clean up cache
You’ve probably heard “Remove your cache” as a web browser troubleshooting tip. In fact, your Mac stores a lot of information in files called caches, allowing fast access to that data and reducing the need to get it from the original source again. Unfortunately, those files take a lot of space on your Mac, and instead of speeding the things up, they slow your computer down. Therefore, if you want to give your system a boost, clean your Mac from the cache files.
There are two ways to do that: you can delete them manually or use a MacBook cleaner like CleanMyMac X to do the job for you. Of course, the second way is an easy and fast one. However, if you decide to clean up the cache manually, check out a comprehensive guide on “How to Clear Cache on a Mac.”
2. Uninstall apps you don’t use
The applications you’ve installed on your Mac take up space, of course. And over time when your Mac becomes full of different apps, it may start running slowly. How to clean MacBook? In the first place, you need to remove the apps you no longer use or need. To do this, right-click on the app you want to remove and choose Move to Bin.

Open System Preferences.
Go to Users & Groups.
Choose your nickname on the left.
Choose the Login Items tab.
Check startup programs you want to remove.
Press the “–” sign below.

Here’s how to clean your MacBook from the trash:

You can choose any file in every category (Applications, Bin, Documents, etc.) and click Delete to remove it and optimize space. Look through other recommendations and make the necessary changes to use your Mac’s space more efficiently.
6. Delete large and old files
It has always been a rule of thumb among computer geeks, that you should keep a minimum of 15-20% of free space on your main hard drive. This is just a rough estimation, but the more free space you have, the faster your Mac works. A computer magazine once performed a test on this, which concluded that the difference in speed can reach as much as 35%. If you work with heavy graphics or video rendering, even more free space is recommended.
How to have more free space? Delete large and old files.
The first way is totally manual and requires you to find them one by one, while for the second way, you just need to make two clicks and CleanMyMac X will do the job for you.

7. Remove old iOS backups
Having your files backed up is a wonderful thing. But over time your Mac becomes overloaded with old backups that take gigabytes of storage on your hard drive. That’s why you should consider removing the old iOS backups you no longer need.
Each backup remains stored on your computer and is accessible via iTunes. To delete the old backups, you need to do the following:
Choose the Apple menu and then select About This Mac.
Go to the Storage tab and click Manage.
Here, choose iOS Files.
Select the backup you want to remove and click Delete.
Confirm and you’re done!
That’s it! The backup files are gone from your Mac forever.
8. Wipe out Language files
Unused language localizations take up about 1 GB of storage space. Mac applications come with language files for every language they support. It allows starting using the app in that language immediately. Cool, right? Not always. Just consider: when was the last time you used the app in Bengali or Korean? Since you don’t speak those languages, such files just waste space on your Mac. You need to remove the unnecessary language files and clean MacBook from that clutter.
How to delete the language files? Go to Finder > Applications, then right-click the app which language files you want to remove and choose Show Package Contents. Open the Resources folder and then find folders ending with “.lproj.” Every folder contains language files for one particular language. Note that for every app you should manually find and select the files to remove. But there is an automatic way to delete the language files that will save you tons of time — CleanMyMac X. Just download the application (for free) and it will do the job for you.
9. Delete old DMGs
Disk images (DMGs) often take up valuable space on your Mac. Here’s how to perform a Mac cleanup and get rid of those files:

Then delete all files that have .dmg extensions. Don’t forget to remove them from Trash as well.
CleanMyMac X allows you to locate and delete DMGs quicker. With its System Junk module you can remove unused disk image in the single click of a button:

10. Remove duplicates
Useless copies of your documents, files, and photos eat up your Mac’s precious space. Therefore, if you wonder how to clean up a Mac and boost its performance, try to delete the duplicates. Note that the process of finding and removing the duplicates requires either a lot of patience and time (if you decide to delete them manually) or a duplicate finder app. Whatever method you choose, make sure to check out this article on “How to Find Duplicates on Mac.”
11. Tidy up your desktop
Many people use Desktop as their primary destination for files. But this could be tricky because your OS treats every file on a desktop as an active window. When items on your desktop are too many, Finder gets substantially slower. This leads us to the most compelling advice in this article — cleaning up desktop does miracles!
Rather than just leaving every file on your desktop, organize them into folders. The latest macOS does that automatically thanks to the Stacks feature. You can also use Google Drive, Dropbox or any external storage device to save your files and keep your desktop tidy.
12. Clean your Mac’s keyboard
Our last but not least advice is to wipe your Mac’s keyboard. As you use your keyboard daily, it quickly gets dirty. Moreover, all those crumbs may live under the keys forever!
If you were wondering how to clean Mac’s keyboard, there are no special rules here. You can try blowing the dust and other particles out of your keyboard once in a while. Disinfecting wipes and alcohol-based sprays may also prove useful. Just choose the piece of fabric and wipe the keys gently to make them clean and shiny!
All in all, be careful with your system files. Don’t delete things you’re not sure about. If you are not completely confident that you can manage the task by yourself, better use a dedicated utility like CleanMyMac X to get a fresh and clean Mac in just two clicks.
