    What is a Mac Virus?

    Mac virus refers to those viruses targeted to Mac and Mac users. Just like with any computer, Mac viruses will infect your system and replicate while rewriting the codes for other programs in your computer. Mac viruses form part of the macOS malware.

    Mac virus authors build the virus to be unnoticeable while infecting your system. This makes Mac viruses rank among the most dangerous security threats to the macOS. If you start noticing unusual signs such as apps appearing in your Mac computer which you don’t recall installing, your Mac is likely infected.

    Now, this doesn’t mean that every time you see such a sign your computer is infected. Sometimes it could be a problem regarding configuration or just an updated version of an existing application that has changed names or icons.

    There are various ways of spreading the virus. The most common one is through software packing.  You might have unintentionally installed a virus riddled program thereby exposing your Mac. Applications such as streaming tools and file converters are among the popular ones used. Other methods of virus spreading are through email attachments and web links

    Ergo, you should be careful when installing software, especially from unknown sources. If you notice a virus infection, you should quickly remove it or ask for guidance if you are stuck or don’t know what to do. We hope after reading this article, you won’t need to seek technical help.

    What are the types of Viruses and Malware?

    There are numerous classifications of malware, each intended to bring harm uniquely. Some malware may be harmless but pave the way for more dangerous malware. Here are the most common forms of malware that continue to wreak havoc.

    1. Virus – Just like its biological counterpart, this type of malware replicates and modifies some programs with its code. Usually, it lays dormant until it’s executed. The infected programs become corrupt and fail to work correctly as they should. They can also spread uncontrollably and damage the system`s core functionality. A virus appears as an executable file (.exe).
    2. Spyware – Spyware is malware designed to spy on a user. It collects and sends sensitive information to its authors without a user`s knowledge. Depending on the design, spyware uses stealth to carry out its operations. It collects confidential information such as a user`s browsing habits and personal information, especially information like the name, social security numbers, biometric data, credit card number and email address of users.
    3. Ransomware – This malware encrypts files found in a device and even locks users out of their devices. It then displays a message with information on how you can decrypt the files and gain access to your device. Usually, it gives instructions on how to pay a ransom mostly in the form of cryptocurrencies.
    4. Trojan/Trojan horse – This malware masquerades itself as something useful or legit. It is a trick used to fool you to get the Trojan into your own device`s system. Once granted access, it creates a backdoor for other malware to infiltrate your system.
    5. Keylogger – As its name suggests, it’s a malware used to monitor and record keystrokes you perform on a keyboard. Once a specified amount of information is logged, a keylogger transmits the data to the author. The data is then analyzed for various sensitive data, including usernames, emails, usernames and passwords, as well as bank details.
    6. Adware/advertising malware – It’s a form of persistent malware that installs itself without any direct permission from a user. The malware continuously displays ads in the form of banners, autopay commercials and pop-ups. Sometimes, adware can alter a user`s search results to show ads or redirect them to advertising websites.
    7. Worm – It is a type of malware whose primary function is to self-replicate and then spread worms other computing devices in a network. A worm can cause significant network disruptions and may alter data and files in some cases.
    8. Rootkit – It’s a malware that gives its developer privileges or root access in the affected computing system.

    How to know if your Mac has a virus?

    Mac viruses are designed to be unnoticeable. Fortunately, some symptoms and behaviours can tell you if your Mac is infected. You don’t want to embark on the virus removal task without actually confirming that your computer is infected. Your Mac may be infected if it starts showing signs such as sudden reboots, incessant pop-ups amongst others.

    Some detailed signs include:

    • Your Mac starts showing erratic behaviours and performing unauthorised actions

    Your Mac can start running unusual processes even with administrative rights. These processes are usually stealth and intrusive.

    In some cases, the viruses can seek to activate the camera or microphone.

    • It becomes slow when loading applications as well as pages in the browser

    Your Mac starts working sluggishly in a sense akin to that of a heavy process running in the background. If this happens yet your Mac has plenty of storage, it likely is infected with a virus. The virus could be responsible for using up the majority of the CPU resources.

    • Pop-up ads flood your computer

    Even pages that you don’t expect to get overlaid by ads such as Wikipedia will show adverts. Sometimes these pop-ups may appear on your desktop. Especially, watch out for ads that are unrelated to your browsing activities.

    • Applications you didn’t install show up

    It could also be a toolbar on your browser which you don’t recall ever installing. If you notice a browser extension that is appearing in your browser for the first time, it may be a virus. It could also be an application claiming to be an antivirus.

    • Some applications start demanding your login credentials

    Some intrusive applications or web pages will ask for your log in details to get access to your data. Although other issues can cause these symptoms, it is recommended you run a scan on your computer to eliminate the chances that it is a virus.

    For instance, your Mac could run slow because of many other reasons.

    If indeed it is a virus, remain calm and start the process of virus removal depending on the virus that has affected your Mac.

    Best Free Mac Virus Removal and Malware Removal Solutions in 2020:

    1. Use Anti-malware Software

    The most recommendable and useful way of removing malware from your device is by using a reputable antivirus or anti-malware software. This is software engineered to detect, clean and shield your device from new malware infections. All you have to do is get a reliable antivirus or anti-malware software like Malwarebytes.

    To get started, download the software. If you disconnected your device from the internet for safety reasons when you suspected that you might be infected, reconnect it so you can download and install the software as well as update it. If you can’t download the software on the infected device or can`t access the internet, use another device, save it somewhere and take it to the infected device. Then proceed as follows:

    1. Launch Malwarebytes software
    2. On the software`s Dashboard section, click the `Scan now’ option to perform a threat scan
    3. Once the results show up, select the items you intend to disable or quarantine. The detected software might be the one bringing malware
    4. Finally, click the quarantine button to move the selected items to the quarantine section
    5. If you wish to get rid of the detected items, go to the Quarantine section and click the Delete button.

    There is also other useful antimalware software you can get. They will protect your device from any future threats and also offer you other security features as well.

    2. Protect Your Device Against Malware

    When it comes to malware infections, prevention might work better than the cure. Luckily, there are a few common sense, easy behavior that minimizes the chances of running into malicious software.

    • Double-check downloads – From official storefronts to pirating sites, malware is usually lurking just around the corner. So before you download, ensure you double-check that the provider is trustworthy by carefully reading comments and reviews about it.
    • Don’t trust online strangers – Social engineering, which includes fake profiles, curiosity-tickling offers, abrupt alerts and strange emails, are among the top methods of spreading malware. Don’t click on something if you don’t have an idea of what it is.
    • Ensure you are careful when you browse the internet – Malware can be found almost everywhere but tends to be more common in websites with poor or no backend security, especially small, local sites. If you stick to secure, large, reputable websites, you can greatly minimize the risk of encountering malware.
    • Use an ad-blocker – Adware is a common type of malware you can avoid when you use an adblocker. Malvertising, where online criminals use infected pop-ups or banners to infect your device, is happening at an alarming rate. You can`t spot or know which ads are maliciou: so it’s advisable to stay safe by blocking them with a reliable, effective ad-blocker.
    • Be mindful of using free Wi-Fi – When using a phone or laptop in a public place or café, be wary of connecting to free Wi-Fi. Avoid exposing personal and sensitive information through online banking and shopping. Hackers might channel malware to your device or access your data without your knowledge. If you must use free Wi-Fi, ensure you use a VPN connection. It protects your connection by encrypting your data.

    3. Improve Your Defenses

    • Make Backups Make regular backups of documents, photos or files in your device and store them on an external hard drive or cloud storage. This can help prevent the loss of important data should you face a malware attack.
    • Keep your protection up-to-date – As discussed above, using anti-malware software is the best way to stay safe from malware infections. However, you need to keep the anti-malware software updated to protect your device from any emerging malware threats. Keeping it up to date is crucial because new malware is being created all the time, so even if you downloaded your antimalware a month ago, it might require updating now.
