Follow the steps listed on Apples support page but remember: this measure is temporary, and you will still need to look for malware on Mac.

How Virus Infects Your Mac

Any malicious entity like a malware or virus can affect your Mac in more ways than you can imagine. If left unchecked, it can even get rid of your saved data, exploit your personal files, and even corrupt the Mac storage. Once the virus enters the Mac system from an external source, it can go to its core firmware components as well. The following are some of the major kinds of malicious entities that can affect your Mac.

This is one of the most commonly found malicious entities on a Mac. Ideally, it would generate unwanted pop-ups while browsing or would redirect you to certain websites without your permission. The main motive is to generate more ad revenue or clicks for the perpetrator.

These are extremely harmful malware that would keep running in the background without getting noticed. Most of the sniffers are keyloggers that would maintain a record of the strings that you have typed. In this way, they try to hijack your accounts by retrieving your passwords.

  • Trojan horses

As the name suggests, Trojan Horse appears to be an authentic application, but in reality, it is a fake malware. Once the Trojan Horse is installed, it would infect your system adversely. For instance, MacDownloader is a popular Trojan Horse that disguises to be something else and tries to steal Keychain data instead.

    How To Check For Viruses On Mac

    Choosing the best Mac antivirus for you is not to be taken lightly. You cannot simply go with the most convenient option because it’s cheap or it’s what your friend is using. The protection you need might be, after all, different from others.

    The first thing you need to decide is how much you’re willing to spend on a subscription or if you’re willing to spend any money at all. It’s worth remembering that while free antivirus products are effective at protecting against threats, they also lack certain premium features.

    If you have multiple systems on your network, for example, you’re at a higher risk of cyberattacks. More users means more endpoints to target. Additional management tools, typically available behind a paid subscription, let you set policies can help mitigate this risk.

    Speaking of which, you do need to consider all the security features you need, from basic ones like real-time protection, parental controls and a password manager to access to secure VPN and dark web monitoring.

    Finally, you need to find out just how big of an impact the antivirus software you’re considering has on your system. Some of them take up considerable bandwidth, which can be taxing on your computer especially if you’re regularly performing taxing tasks.

    Dont Use Any Passwords And Change Them As Soon As You Can

    From the moment you suspect you have a virus you shouldnt type any passwords or login details in case a hidden keylogger is running. This is a very common component with malware.

    Beware that many keylogger-based malware or viruses also periodically secretly take screenshots, so be careful not to expose any passwords by copying and pasting from a document, for example, or by clicking the Show Password box that sometimes appears within dialog boxes.

    Once you are free of the virus you should change all your passwords, and we really do mean all of them including those for websites, cloud services, apps, and so on.

    • Your Mac suddenly becomes sluggish or laggy in everyday use, as if theres some software running in the background chewing up resources
    • You find theres a new toolbar in your browser that you didnt 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 youve never heard of
    • All web pages are overlaid with adverts even those where you dont expect to see adverts, such as Wikipedia
    • Going to your favourite sites doesnt 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 youre doing or any program thats running

    If you get any of these symptoms then dont panic: they dont necessarily mean you have a malware or virus infection on your Mac. Theres a thousand reasons why a Mac right run slowly, for example.

    Do Macs Need Antivirus Software

    Most antivirus experts agree that while Apples security software is fairly good, its not foolproof. XProtect does not identify as many types of potential malware as third-party antivirus software, and gaps in its library of malicious programs can leave users exposed.2 Part of the problem is that the software relies heavily on Apple identifying and tagging malware and viruses, and since Apple isnt a dedicated security company, it doesnt keep track of nearly as many threats as third-party products. According to Malwarebytes, the number of serious malware attacks identified on Macs increased by 61 percent from 2019 to 2020, while less malicious adware rates declined, a worrying trend that suggests installing dedicated antivirus software is a wise decision.3 That being said, its important to make sure the antivirus you choose works on a Mac, which is why we tested the software we listed as the best antivirus software for Macs.

    A guide to virus scanning and removal on your Mac.

    Viruses and malware can cause serious damage to your Mac, which is why macOS includes built-in tools to verify the software you install comes from a reliable source.

    Tips To Scan Mac For Viruses

    If you own a mac or any laptop for that matter, its important you are aware of viruses and regularly scan your device for malware. Viruses can be particularly nasty and get a lot worse if not treated as soon as you think you have one. Many viruses are there to steal your data, hijack your browser or track your keys in order to gain access to your personal accounts. They are very sneaky and can hide in your applications, your documents or attach to your browser extensions. As technology continues to develop, the more sophisticated viruses will become, making it even more important that you are clued up about them and have certain actions in place to avoid them.

    So what can you do to scan your Apple Mac for viruses? Luckily, there are many ways to get to know how to scan your whole system for malware. This involves checking your activity monitor, checking for unwanted applications, reviewing your browser extensions and having an antivirus system installed to scan your Apple Mac. Below is our guide to scanning your Mac for viruses.

    Three Layers Of Defense

    Malware defenses are structured in three layers:

    1. Prevent launch or execution of malware: App Store, or Gatekeeper combined with Notarization

    2. Block malware from running on customer systems: Gatekeeper, Notarization, and XProtect

    3. Remediate malware that has executed: XProtect

    The first layer of defense is designed to inhibit the distribution of malware, and prevent it from launching even oncethis is the goal of the App Store, and Gatekeeper combined with Notarization.

    The next layer of defense is to help ensure that if malware appears on any Mac, its quickly identified and blocked, both to halt spread and to remediate the Mac systems its already gained a foothold on. XProtect adds to this defense, along with Gatekeeper and Notarization.

    Finally, XProtect acts to remediate malware that has managed to successfully execute.

    These protections, further described below, combine to support best-practice protection from viruses and malware. There are additional protections, particularly on a Mac with Apple silicon, to limit the potential damage of malware that does manage to execute. See Protecting app access to user data for ways that macOS can help protect user data from malware, and Operating system integrity for ways macOS can limit the actions malware can take on the system.
