People often think Macs are malware and viruses free. Well, that’s not true. With evolution, people have found ways to attack everything, even the most secured system like Mac OS.

Without further ado, let’s get started.

What Are The Symptoms And How To Diagnose them?

Every now and again malware or a virus does get make it through into the wild, where there’s at least a risk of infection, so a basic knowledge of security is good for any Mac users.

Here are just some of the symptoms of malware or viruses you might watch out for:

  • Your Mac suddenly becomes sluggish or laggy in everyday use, as if there’s some software running in the background chewing up resources;
  • You find there’s a new toolbar in your browser that you didn’t install. Typically these toolbars claim to make it easier to search or shop;
  • You find any web searches are unexpectedly redirected away from your usual search engine to some site you’ve never heard of (or the results appear in a page that’s faked up to look like your usual search engine);
  • All web pages are overlaid with adverts – even those where you don’t expect to see adverts, such as Wikipedia;
  • Going to your favorite sites don’t always work, as if something is randomly redirecting you to spam advertising pages;
  • Advertising windows pop up on your desktop, seemingly unconnected with any browsing you’re doing or any program that’s running.

How Your Mac Gets Malware

There are many reasons on how malware can get onto your computer. Here are the top 3 reasons:

1. Malicious Software

As so you know, malware is nothing but a computer software or program. So by unknowingly install any programs that could potentially harm your computer, you are inviting malware to your system.

Some of the most common ways how this software creeps into your computer are

  • Emails
  • Pop-ups
  • Installed along with other programs
  • Ads
  • Cleaner tools

There are also protections in place that should mean macOS’s Gatekeeper technology that should recognize any malicious software and stop you from installing it – as long as it’s not very new (it can take Apple a few days or weeks to address new malware).

Should macOS detect a malicious app it will let you know and will ask you to move it to the Trash. Read more about Apple’s built-in virus protection here: How Apple protects your Mac from Malware.

2. Hazardous Files

Sometimes malware or viruses might be disguised as an image file, word processing or PDF document that you open either without realizing what it is.

This method is one of the most effective as by disguising as a file, what users would normally do is to execute or open it, which directly initiates the malware process.

Unlike the above way, the programs may be installed or sitting on your system, but without launching them, you won’t be affected.

3. Fake Technical Service

Sometimes you may consider calling a computer repair service provider to come and fix your computer, which you might think are infected.

But in reality, they could turn out to be one of those fakes company, telling you that your system is infected with malware and would run the computer through series of repairment, which in reality, are installing the malicious programs.

5 Steps To Remove Malware From Mac

Follow these step-by-step to remove malware from your computer if you found it’s infected

1. Keep System Offline

Malware is designed to steal users’ information. This information is then transferred to the people behind it, which is through the internet.

Some of the things to do are switch off your Wifi, turn of any updates and stop any online transactions.

2. Monitor The Activity

Next is to identify the malware software on your computer. You can easily do this by monitoring the apps running in the background, which seems to be using lots of your resources. For example, CPU and RAM.

Another way is to see programs that keep on executing, even though you have quit them or some unknown new programs installed.

3. Uninstall The Malicious Program

Once you know the culprit, it’s time to uninstall it. However, in some cases, uninstalling is not enough. Some malware won’t just be completely removed, even after uninstalling.

They would just replicate themselves from the pre-existing file. In that case, you have to proceed to the next step, if this doesn’t work out.

4. Deep Cleaning

If you can’t remove the malware, you need to perform deep cleaning. Open the Mac App Store and download the free-of-charge Bitdefender Virus Scanner.

Once it’s downloaded and installed, open the app and click the Update Definitions button, then once that’s completed click the Deep Scan button. Follow the instructions to allow the app full access to your Mac’s hard disk.

5. Reinstall The System

If uninstalling and deep cleaning don’t work, the best way to approach this is to simply reinstall your Mac OS. This will potentially wipe out all the files, as well as malicious software.

Don’t forget to backup your system before you proceed.

However, Mac users are always advised to only use apps from the Mac Store. But of course, certain applications like Photoshop, for example, can’t be found, and you need to install from the third party place.

2. Don’t Click On Ads And Check The Programs Every time You Install

Avoid clicking on clickbait ads which guarantees you some false hope like winning the lottery etc.

Whenever installing new software, check every time for any checkbox that would be automatically checked for additional program installation.

3. Keep The Anti-Virus And System Up To Date

keep your anti-virus and the system up to date. Watch out for any bug fixed or loopholes that Apple constantly monitored and rolled out.
