What is malware?

Malware is short for malicious software, which is a broad term for viruses, worms, adware, ransomware, and other computer programs designed to inflict harm.

 

While some malware  simply annoys you with pop-up ads, others can seriously slow down your Mac. There’s also malware that can steal your personal and financial information. Put simply, all malware is different, and you don’t want any of it on your Mac.  

Signs of a malware infection

How do you know if your Mac is infected with a virus? Unfortunately, the presence of malware  is not always immediately clear. Some viruses that are particularly pernicious can take up residence on your Mac for months without you even noticing them. But in most cases, it’s not too difficult to tell if your Mac has a malware problem.

 

Look out for these signs of a malware infection:

  • Slow performance

Nothing ruins a potentially productive day like a slow Mac. Is the sudden sluggishness of your Mac caused by a hardware issue? Perhaps. But it’s more likely to be a symptom of malware infection, especially if your Mac is new. So postpone a Genius Bar appointment just yet.

  • Excessive ads

If you are suddenly bombarded with ads and intrusive pop-ups, adware is to blame. Even though it is not the most malicious form of malware, it is arguably the most annoying. Chances are you  downloaded it unknowingly while browsing the web.

  • Browser homepage change

When your Mac is infected with a virus, your browser homepage may change without your consent. While reversing this change is not difficult, it must be done by hand, which is a needless inconvenience.

  • Unwanted redirects

Unwanted redirects to suspicious websites are yet another sign of malware infection. Not only does it spoil your browsing experience, but it also tracks your browsing habits.

  • Security alert messages

An alert message informing you about a Mac malware detection is a scam attempt. Usually, the alert message prompts you to call a phone number or click the OK button. Don’t do it — avoid becoming a cybercrime victim.

  • Ransom demands

Ransomware locks your data to extort money from you. You may receive a message informing you about a fine you need to pay. Cybercriminals can also hit you with an outright ransom demand.

 

So now you know the common signs of malware infection. Although prevention is always better than the cure, if you do spot one or more of them, it’s time to start malware removal.  

How to set up and run an automatic malware scan on Mac

Malware cannot sneak up on you if you scan for it regularly. Think of it as a routine essential to the normal functioning of your Mac. Rather than dealing with malware when it’s too late, you should proactively seek out any unpleasant surprises hiding on your device.

 

Of course, few people love their Mac enough to run daily malware checks manually. What you need is a simple way to run a security check on Mac automatically. Ideally, via an unobtrusive app that lives on your device and takes care of it for you. I am referring, of course, to MacKeeper, which is designed to do just that. 

 

MacKeeper removes any malware plaguing your Mac and safeguards it against online threats in real-time. The app has been certified by an IT security research organization based in Germany, the AV-Test Institute.

How to remove malware manually

If your malware problem is not particularly challenging, you can easily deal with it manually. While we grant it isn't the fastest way to remove Malware, it might still work.

Remove suspicious apps

Not only do apps gobble up storage space, but some of them can also harbor malware. Go through all your apps carefully and remove the ones you don’t remember installing.

Remove suspicious extensions

Extensions improve your browsing experience, but they can also ruin it by slowing down your Mac or letting a malware infection in.

Clear the Downloads folder

Everything you download onto your Mac goes into the Downloads folder. However, along with useful files, it can also contain viruses. Therefore, consider clearing the Downloads folder out regularly.

 

Important: Some deleted files cannot be restored. Therefore, you should be absolutely certain that what you are about to delete is a virus rather than an important file. If you are not a tech-savvy Mac user, leave the task of malware removal to the experts.

Tips to protect your Mac from malware

Apple goes to great lengths to guard your Mac against malware. Mac’s built-in antivirus XProtect  runs continuously in the background to seek out and quarantine harmful software. Gatekeeper is a security technology designed to ensure that only safe apps are allowed to run on your device. There’s also App Sandbox mode which allows you to isolate some apps and contain any damage they may cause.

 

Indeed, Apple is vigilant about the security of your Mac. But it doesn’t mean you should let your guard down.

 

Running MacKeeper’s Antivirus in the background helps a lot. You should also follow these simple tips to keep your Mac safe.

Watch out for suspicious emails

Never respond to emails asking you to provide personal information or install an app. And never ever  open emails with attachments from unknown senders. But most importantly, always follow your gut: if an email seems suspicious, it probably is — stay away from it.

Keep your Mac up-to-date

Make sure your Mac always runs the latest software. When notified about software updates, install them immediately. By following this simple rule, you’ll get rid of any security flaws regularly addressed by Apple. 

Install apps from reliable sources

With every app from an unreliable source comes a risk of malware infection. Therefore, ensure that only trustworthy software runs on your Mac. The easiest way to do it is to download all apps from the App Store or the websites of reliable software developers.  

Be wary of browser pop-ups

Look closely at any pop-up prompting you to do something. Does it have a poor quality logo, spelling errors, or an URL? Don’t click on it if it looks even slightly suspicious.

Stay away from free downloads

Although not all free software is unsafe, some free apps do have the potential to harm your Mac. Before downloading any free software, make sure you trust its developers.

Takeaway message

Once your Mac is infected, malware can stay there forever, ruining your user experience and compromising your privacy. Unless, of course, you follow this guide on malware removal. And even then, success is far from guaranteed.

 

Because of the widespread threat of malware, it’s essential to adopt safe browsing habits. It also never hurts to have a solid antivirus installed on your Mac.

 

With a pinch of precaution and a little bit of caution, your Mac will stay virus-free.
