    Tips On How To Protect Mac From Malware

    Consider these simple tips and keep your Mac as safe as ever.

    1. Set Up Your Gatekeeper And Firewall

    The first step that you should take towards managing the security of your Mac in order to protect it against malware is to check the security settings as that’s what manages your Mac’s Gatekeeper. Gatekeeper comes as your inbuilt security measure for Mac which blocks anything that tries to install itself or open on your Mac if it does not contain any digital signature and is not Apple approved. If you’ve ever installed anything downloaded from outside the Apple’s App Store then you’d probably be aware of this thing as everytime you try something like that, you get a warning message.

    In order to check these security settings, open System Preferences on your Mac and then head to Security & Privacy. When on that screen, stay on General Tab. At bottom of this screen, you’ll see a section for “Allow Apps Downloaded From”. Check the option labeled “Mac App Store & Identified Developers”.

    It means that you’ll only be able to install the applications that are approved and Apple considers them safe to be installed. In addition, it will still be possible for you to install quite a few different apps that are not from App Store.

    If you want to somehow bypass this check in order to install the apps you trust, just press and hold Ctrl key and click dmg file before selectingopen. Afterwards, you can be able to install the apps that aren’t Apple-approved.

    Besides blocking any suspicious applications, Gatekeeper for Mac also blocks any vulnerable plugins for Safari such as Java or Flash in the bid to keep the Mac safe. There is an XProtect file in which it keeps all the malware definitions and it also features some type of anti-phishing technology for Safari. As soon as you browse some suspicious website, you will be alerted immediately and the page will be disabled.

    Besides Gatekeeper, ensure that you have Firewall turned On. It will make sure that any undesirable incoming connections are blocked and your Mac is not exposed to internet or any other computer that is part of the network. You can do this by going to same Security & Privacy page in System Preferences and click firewall tab there for ensuring that it is turned on.

    1. Stay Updated

    One of the most significant tips is making sure that your macOS is fully updated. When installing any updates to macOS, most of the people are interested in cosmetic changes or feature updates. And if no such thing is coming as part of the update, people try to stick to what they already have and do not go for the update.

    However, with every macOS update, malware definitions are updated and XProtect file is introduced with some of the latest malware threats that may be a problem for mac users in times to come. And, when the malware definitions are fully up-to-date in XProtect file, it can better combat against any type of malware that may try to infect your mac. Besides introducing updates to the XProtect file, many Mac updates patch possible vulnerabilities inside the macOS itself. So, always ensure that you remain a step ahead of latest malware by keep your macOS updated at all times.

    1. Try Third-Party Scans

    Though Apple has itself introduced some of the best malware protection mechanisms as part of the macOS, running third-party scans as an extra security measure doesn’t hurt either. Just like the case with OSX/Dok Trojan horse, tricking Apple is not impossible at all.

    To be fortunate, you have a few great options to try when it comes to third-party scans. And, the best part is that they are available for free as well. You can try apps like Malwarebytes and Bitdefender to perform scans off and on and detect and remove any possible malware from your mac.

    1. Stay Vigilant

    Take it as an important tip and always stay vigilant. It makes sense to take the precautionary measures for avoiding malware but, with malware getting ever smarter, the best you can do is to stay vigilant.

    For instance, take OSX/Dok Trojan horse which can easily bypass gatekeeper in macOS as it gets a certificate by accessing an authentic developer’s account. Once this Trojan gets into your Mac, it targets you with email phishing.

    Make sure that you do not respond to any emails whatsoever that ask you for passwords, reply with your personal details, or install software from email directly.

    One more example that can be quoted here to tell how smart malware have become is the MacDownloader. The malware tricked Mac users through some fake updates to Adobe flash. In case, if you get messages for updating any software or plug-ins that you’re using, you should better avoid updating directly through that message. Make sure that you check with official website of that software provider to download any updates that may be available. To be lucky enough, Apple makes sure that everything stays up-to-date when it comes to malware and virus definitions, but it is always best to stay aware of what’s going on around.

    So, if you want to know exactly how to protect mac from malware, these are some of the basic things that you can do. Hopefully, you’d find these tips helpful for you and will allow you to keep your mac completely safe.
