How to scan your Mac for viruses online?
Truth is there are lots of ads and websites that promise free online virus scan and removal for Mac. But most of them are ironically also affiliated with malware players trying to get into your Mac for their malicious purposes and make things even worse. There are a few ways to substitute online virus scan that macOS needs, and protect your Mac so no malware can get in.
1. Update your software
As searching for 'online virus scan Mac' doesn't help much, the first thing to do to really protect your Mac is update to the latest version of macOS as well as turn on auto-updates for all your apps. The latest versions of software include all the necessary security patches known to developers, so it's a good starting place.
- Check the App Store for software updates and install them.
- In System Preferences > Software Update, check the box to 'Automatically keep my Mac up to date.'
- Click Advanced and select all the options there.
2. Back up your Mac
Another precaution against viruses you can take is backing up your documents. For instance, you can use your Mac's built-in Time Machine utility to save your backup to an external hard drive. That way, frequent backups will allow you to restore recent versions of your documents should they get deleted or encrypted by a virus.
- Connect an external hard drive.
- Go to System Preferences > Select Backup Disk and turn it on.
- Choose Back Up Automatically.
3. Turn on Mac's built-in protection
If you've ever got a warning on your computer asking whether you're sure you want to download something, you've seen File Quarantine in action. It lets you decline to download an item in case you don't completely trust the source it's coming from.
Another built-in utility Gatekeeper checks that there's an electronic signature from an approved Mac supplier on any item you attempt to download. So making sure it's turned on is a great way to protect yourself from downloading something malicious.
- Go to System Preferences > Security & Privacy.
- Under 'Allow apps downloaded from,' ensure that 'App Store and identified developers' or 'App Store' and not 'Anywhere' is selected.
- From macOS Mojave onwards, the 'Anywhere' option is no longer available to increase security. That's why updating your macOS is crucial.
4. Examine your Disk Utility
Navigating to Disk Utility will give you a sense of what's taking up space on your hard drive. You can also click on First Aid to run a scan of the hard drive and repair any errors. Make a note of the types of things taking up space, especially if any category is unusually large — this would be a good one to target directly or to check on later to see if it became smaller through the measures you are undertaking.
5. Clean up your hard drive
Unused apps, redundant copies of documents, and old media files — getting rid of these is likely to help with deleting any existing viruses and also free up space and speed up your Mac at the same time.
In general, cleaning up your computer will improve your day-to-day experience and ultimately mean you won't have to buy a new one too soon, saving you money.
- Launch the Applications folder (Cmd + Shift + A).
- Go through the list and uninstall any programs you're no longer using.
- Then check your Documents, Pictures, Movies, and Music folders for files you haven't been using in a long time.
- Empty the Trash when you're done.

7. Encrypt your Mac
It might come as a surprise but files on your Mac are easily readable to anyone who can gain an unauthorized access. They will be able to read your documents, apps, messages, etc. To prevent this, you need to turn on Mac's built-in encryption engine called FileVault.
- Go System Preferences > Security & Privacy.
- Turn On FileVault and wait for the encryption to finish. Done!
8. Protect and optimize your Mac in one click
If you have the time and are willing to be methodical about the cleanups you need to do and how often you need to do them — ideally once a month — you can go through the above checklist every time.
However, why not save some time and make sure you do it the right way.

For such cases CleanMyMac has a real-time monitor that detects any attempts for unauthorized access from malware apps.
After you finish scanning for malware, don't forget to perform additional scans for Optimization, Maintenance, Junk, and an overall Smart Scan. In each case, CleanMyMac X takes care of all the tasks necessary to protect and optimize your Mac. Repeat the process every week or so and you are set.

Most common ways to know if your Mac has a virus
There once was a time when your Mac computer were considered to be relatively immune to viruses and malware. Users were blissfully secure and never had to worry about landing infections, that the concern of Windows OS users. But times have changed – dramatically. As a matter of fact, according to some experts, Macs are now far more vulnerable to externals threats than PC's than ever before in history.
This is in part due to the fact that Macs now have a bigger market share than in previous years, so it only made sense for hackers to create viruses for the popular type of computers. But since Mac OS machines are becoming more and more popular, the numbers of malicious code written for them are growing as well.
Many of our users ask us 'do i have a virus on my mac', this brings us to the question as to how does one actually spot a virus infection on a Mac computer.
Interestingly enough, potential infection symptoms are not that much different on Macs than they are on regular PCs. Here is a list of some of the most common telltale signs of a possible virus present in your system, although they won't all necessarily always be a surefire indication for malware.

- Your Mac will have ads and popups that appear out of the blue.
Advertisements in the forms of banners and popups are common all throughout the web. But sometimes they can start to appear in places where you least expect them to. And they can be quite aggressive, as well, or perhaps refuse to respond when you try to close them. Some may not even offer you the option to close them, which is already a red flag all on its own.
But if different advertising messages begin to appear even when you are not browsing the web (i.e. not within your browsing program), then this is a likely sign of infection. - Your Mac will suddenly restart
This is a glaring one and should never be ignored, especially if it happens on more than just one occasion.
- Your Mac will have warnings about viruses (usually from third-party software).
Ironically, you might actually start seeing warnings about malicious threats on your computer, but these will be coming from third-party software. And as a rule, they may aggressively try and urge you to deal with the issue immediately by clicking there-and-there and doing so-and-so.
- Your Mac will have performance issues and System slowdowns.
Certain malware and virus infections can cause your computer to start using significantly more system resources such as RAM and CPU. For instance, there are different types of viruses that can involve your machine in vast botnets for a variety of different purposes.
They can be involved in DDoS attacks, cryptocurrency mining, spam distribution, etc. And all of these activities could, as a result of the increased CPU consumption, result in a slowdown of your Mac, programs freezing up and similar consequences.

Most common virus infections for your Mac
There are several categories of malicious code or viruses that target Mac computers and here are the most common ones you are likely to encounter:
Adware
Adware isn't exactly malicious, but it is considered to be potentially unwanted software for a number of reasons. And one of these reasons in particular is the fact that ad-generating programs and browser hijackers are generally associated with the risk of exposing your computer to viruses as a result of their intensive advertising practices. You can read more about how adware works, why it's dangerous and some prominent examples of this software category here.
Trojans
Trojans are by far the most notorious type of viruses out there. They are stealthy, versatile and the amount of cyber attacks they are responsible for far outnumbers that of any other type of virus category – for Macs as well. Although Trojan horse viruses can be employed for a wide range of different malicious tasks, in the majority of instances of infection these threats steal sensitive user information, like personal data, usernames, passwords, etc.
A vivid example of a Trojan horse virus that infected millions of Mac computers and made headlines was the Shlayer Trojan.
Ransomware
Ransomware viruses are a pretty big deal, regardless of the operating system you're using – none are safe. There are different subcategories of this malware type, but they all operate on the principle of blocking their victims' access to something in their system and demanding a ransom payment for it. Typically, ransomware will apply an encryption algorithm to the data stored on the infected computer, and unless the victim pays, they will likely permanently lose access to said data.
These are actually among the most rapidly growing virus groups and it's a good idea to read up on them and know what you can do to protect yourself from a potential attack.
Ransomware viruses for Mac have been around for a few years now, and every now and then there's one that particularly stirs up a lot of trouble and often makes the news. Here's a good example of a Mac ransomware variant that caused a lot of noise a few years ago.
Macro Viruses
Macro viruses have always been associated with Microsoft Word documents, where the virus is activated when the victim opens a file and has macros enabled. In such cases the macro virus can run a code to achieve a number of different malicious tasks. For instance, it can corrupt files, access webcams and mics, take screenshots, insert and send data, format your disks and drives, etc. You can read more about how these viruses operate here.
And it wasn't until just a couple of years ago that macro viruses started targeting Mac OS users as well. In fact, the first known attack of this kind on Macs occurred in 2017 and the virus launched a whole list of malicious processes at once.
Does my Mac have a built-in virus scanner?
Anyone who has ever had the discussion with a Mac user regarding the security and safety of their OS has heard that Macs come with integrated protection mechanisms that make it virtually impossible for viruses to infiltrate them. Or so it used to be anyway.
And, in truth, Mac OS computers really do have an antimalware system already built into them when you buy them. The software is known as XProtect and it functions much like your regular antivirus program for PCs. Basically, it scans any new content that is about to come into contact with your Mac for viruses (e.g. new applications you've downloaded).
Here's a fairly good and comprehensive summary of how XProtect works.
Should I install an antivirus for my Mac?
If you ask someone in the Apple Store they will tell you that Mac are super secure. As pointed out in the previous section, Apple has already equipped its computers with an integrated antivirus tool that does its best to protect your Mac from any external threats. It pretty much prevents users from being able to download and install unsafe files from the internet. Unless you are hell-bent on downloading a file, program, application, what have you off the internet, and are willing to disregard the warnings of XProtect, then there's little to no way you can land an infection.
With that in mind, installing any additional antimalware software would be pointless, as you'd disregard its warnings as well. So, to put it simply, XProtect offers sufficient means of security for your system, as long as you let it do its job. Thus, there's no real necessity to enhance your Mac's safety using more antivirus tools.
How to delete malware from your Mac manually

Listen to XProtect
This one is very simple too: just watch out for any alerts from Mac's integrated antivirus software and follow its instructions whenever prompted to. If it's detected something that it deems dangerous – chances are it probably is.
Make sure your web browser is up to date
Regularly installing updates for your browsing program whenever those become available can actually go a long way when it comes to your computer's safety. Depending on the browser you use, this may need to be done manually, so look out for alerts.
Enable Firewall
All computers have a Firewall feature and it exists in order to protect users from unauthorized applications and services from accepting incoming connections.
