Affirming that the Apple device is not infected with the virus is only true for iOS-based devices such as iPhone, iPad but not completely true for Mac. Malware or viruses can still enter places that are most at risk, so getting the basics of security is a must for Mac users. You can refer to the article 3 ways to identify a Mac infected with a virus to check your Mac.

Here are some malware or virus paths that infiltrate the computer. Knowing how a virus infects a Mac helps you find a solution to remove it.

Malware

Malware often pretends to be legitimate software such as antivirus software for Mac, so check user reviews, carefully consider the name of the software vendor to avoid downloading malware. The virus also follows emails or instant messages that infect computers.

Apple has built-in protection, preventing users from installing software like this. It does not allow you to download software that is not registered by the developer. When trying to open these apps you will see a warning saying that the app comes from an unknown developer.

In addition, Apple uses Gatekeeper technology to identify malware and prevent you from installing it. If macOS detects malicious apps will tell you to delete them. However, you should not rely too much on Apple because malware has many other ways to trick you into installing it.

Fake file

Sometimes malware or viruses camouflage into an image file, Word document, PDF so you accidentally open them and infect the computer virus.

Security hole

Malware enters your system through security holes in your browser or other software such as Word processing software, PDF reader software.

System tools or fake updates

Disguised malware looks like a legitimate update to trick users into installing it. It is even more sophisticated when provided through a warning dialog while you are browsing the web. Counterfeit updates for browser plugins or fake system / antivirus optimization apps are one of the popular attack methods.

Quarantine / Gatekeeper file (File quarantine / File awareness quarantine)

As mentioned above, when you open an app that is downloaded from the Internet, you will receive a warning about the file download source and download time. You will then have to choose to open the file if you trust the app. This feature helps you discover apps that do not have a clear origin, thereby avoiding virus infection for the device.

Xprotect

Xprotect is integrated in File Quarantine, when the downloaded file is opened, it checks whether the app is infected with a virus or malware. Xprotect even blocks old versions of legitimate software such as malware-vulnerable Java or Flash plugins.
