How To Scan Mac For Viruses And Malware

How To Check A Macbook For Spying Software

How To Remove A Mac Computer Virus, Malware, Spyware, Maintenance, And Cleaning 2020

The Mac operating system has strong built-in protections against spying software, malware and viruses, but that does not make your computer impervious to infections. According to the New York Times, the growing popularity of Mac computers and MacBook laptops has increasingly made the operating system a target for email phishing scams, social networking viruses and other malware that secretly embed themselves in the system. Safe browsing habits will go a long way in keeping your Macbook secure, but it is prudent to undertake manual scans of your system or install anti-virus software to periodically check your computer for security breaches.

How To Tell If Your Mac Has A Virus

If your Mac has suddenly become very slow and laggy, started regularly crashing or showing error messages, and the sound of your fans whirring keeps you company, you may be suspicious that you have picked up some Mac malware. Another sign is the sudden appearance of annoying pop-up windows or extra toolbars and applications you dont remember installing. These are all signs that you might have a virus on your Mac.

Its not necessarily the case that a virus is to blame though. Mac malware is incredibly rare Mac viruses do exist, in fact there have been a few notable malware and virus reports in recent years, but there are a few reasons why Mac viruses dont tend to take hold. One is the stringent protections Apple builds into macOS, another is the fact that it is exceptionally difficult for a virus to propagate itself and spread to other Macs.

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

Your Mac Is Slow For No Reason

Some Mac malware makes your Mac part of a botnet, which is a global network of computers used for all sorts of things. If your Mac is infected, it could be helping to perform a DDoS attack on a website, mine Bitcoins, or complete any number of tasks that take up CPU power.

If your Mac is constantly slow, even if you don’t have any programs running, this is a possibility. And remember, if malware isn’t the problem, you need to work out what is causing your Mac to run slowly.

Avoid Downloading Malicious Software

Apple has in-built protections that should stop you installing this sort of thing. The company wont allow you to install software that isnt from a registered developer, for example, without first jumping through a few hoops. When you try to open such an app youll see a warning that the application is from an unidentified developer. Of course, its not always going to be the case that this is malware, so it is generally possible to open such software, but you will have to make some changes to your settings in order to do so as we explain here: How to open a Mac app from an unidentified developer.

There are also protections in place that should mean macOSs Gatekeeper technology that should recognise any malicious software and stop you from installing it as long as its not very new . Should macOS detect a malicious app it will let you know and will ask you to move it to the Trash. Read more about Apples built in virus protection here: How Apple protects your Mac from Malware.

However, the malware might have looked like legitimate software, such as a virus scanner that you download and installed in panic after believing yourself to be infected. Check for independent reviews of apps or ask for personal recommendations from others to avoid downloading this kind of thing.

This kind of malware might be downloaded by you, or it might arrive via email, or perhaps even arrive via an instant message.

Ransomware, for example, is usually obvious as some or all files and folders will be encrypted , and you will usually see a popup demanding a ransom payment. Other signs include ad popups, unexpected slowdowns, browser redirection, and applications you dont recognize.

Ultimately though, running a scan using antivirus software will tell you if your system is infected and with what.

    Checking Your Mac For Viruses Wait What

    You may have been led to believe that you dont have to worry about computer viruses on your Mac. And, to some extent, theres truth to that. While your Mac can definitely be infected with malware, Apples built-in malware detection and file quarantine capabilities are meant to make it less likely that youll download and run malicious software.

    Privacy Concerns With Mac Antivirus

    How to scan your PC or Mac for viruses

    We need to be cautious about the privacy implications of the software we choose, and that includes antivirus programs. We recommend considering a few key questions regarding your antivirus software.

    Is the Company Located in a Five Eyes, Nine Eyes, or 14 Eyes Country?

    Five Eyes, Nine Eyes, and 14 Eyes are surveillance alliances in which countries have agreed to turn over data to each other for security or law enforcement reasons. If an antivirus company is based in a country that belongs to one or more of these alliances, that means any country in the alliance can compel the company to turn over your data.

    What Type of Encryption Does the Program Use?

    There are a few different ways in which companies encrypt your data, and its essential to know that your sensitive information is safe. We recommend looking for antivirus software that uses AES 256-bit encryption, the standard the U.S. government uses for top-secret data.

    Whats in the Privacy Policy?

    As with any digital product, its a good idea to examine the privacy policy for an antivirus. Some antivirus software options sell user data or share it with third parties, which is both invasive and a potential threat to your security, since the more places your sensitive data is stored, the more likely it is to be stolen.

    What To Do If You Find Malware On Your Mac

    If you do ever pick up an infection, then you need to know how to remove malware from your Mac. This could involve manually removing apps or extensions. It could even involve resetting your Mac or restoring from a backup.

    But usually, the best way to remove viruses and other malware is to use an antivirus tool like MacKeeper. As well as helping to detect malware on Macs, its real-time protection will also work to prevent it ever getting on there in the first place.

    Is My Mac Infected

    How do you know if your Mac has a malware infection? If you think it’s infected, try our free virus scanner, and look for such clues as:

    • You land on a web page youve selected, and advertising banners start to intrude on you aggressively.
    • You notice that random web page text suddenly has a hyperlink.
    • Browser pop ups get in your face, earnestly recommending fake updates or other fake software.
    • You notice other unwanted adware programs, which you did not authorize or which were installed without your knowledge.
    • Your Mac crashes, heats up, or runs its fan faster than normal for no apparent reason. It may be working on an intensive task because of a cryptocurrency miner on your system, most likely installed by a Mac Trojan.

    If you see any of the above, or other strange behavior, then its high time you got yourself some cybersecurity protection. Furthermore, though the general consumer may consider cybersecurity synonymous with the term antivirus, the more accurate designation should be anti-malware, a catch-all term that describes all malicious software, regardless of type. For example, viruses and Trojans are two specific types of malicious software, both of which are malware. The fact is, viruses are much less of a thing today, largely because there are far easier ways to infect Macs with Trojans, worms, spyware, and ransomware.

    Delete The File Or App And Empty The Download Folder

    If you believe your Mac was infected after opening a particular file or app and you have a file name to search for, you can attempt to locate that app, delete that file permanently by putting it into the Trash, and then empty the Trash.

    You should also empty the Downloads folder and delete everything in there: drag the whole lot to the Trash, and then empty the Trash.

    However, it is rarely this simple: most malware authors will obfuscate their code so that it uses non-obvious names, which makes it almost impossible to uncover this way.

    Protect Your Mac From Malware

    macOS has many features that help protect your Mac and your personal information from malicious software, or malware. One common way malware is distributed is by embedding it in a harmless-looking app.

  • On your Mac, choose Apple menu > System Preferences, click Security & Privacy , then click General.

    , click it to unlock the preference pane.

  • Select the sources from which youll allow software to be installed:

All the developers of apps in the Mac App Store are identified by Apple, and each app is reviewed before its accepted. macOS checks the app before it opens the first time to be certain it hasnt been modified since the developer shipped it. If theres ever a problem with an app, Apple removes it from the Mac App Store.

  • App Store and identified developers: Allows apps from the Mac App Store and apps from identified developers. Identified developers are registered with Apple and can optionally upload their apps to Apple for a security check. If problems occur with an app, Apple can revoke its authorization. macOS checks the app before it opens the first time to be certain it hasnt been modified since the developer shipped it.
