Find out the most common kinds of malware attacking MacBook Air and learn how to clear machines from any malicious script.
Malware in Mac OS is not a rare scenario anymore. However, malware that targets Mac isn’t as well-developed as viruses found in Windows. The downside is that the threats on Mac system are evolving and the culprits inhabiting the invisible web are progressing in terms of their capabilities to damage the OS by developing their strategies.
There are many MacBook Air machines now all around the world since it became popular among Apple patrons because it is the more affordable version of the MacBook. Due to its popularity, it has gotten the attention of hijackers.
Considering how vulnerable even these well-secured machines are, remembering the late 2000s and the incidents of how the malware in Windows has evolved, people can associate that memory to a time when rogue security software also terrorized the digital ecosystem. Now, these deceptive anti-malware apps are becoming adept in infiltrating the MacBook Air.
Methods of removing known malware from your MacBook Air
Scareware on MacBook Air
Mac Auto Fixer, Mac Tonic, and Advanced Mac Cleaner are some of the examples of this scareware recently. They are segments of bogus utilities in a family of malicious software known for their notoriety. Any of these fake security apps usually gets into the MacBook Air through an installation method called “bundling.”
That means that the machine most likely became infected during the installation of another free software and one of this advertising-supported software, usually a potentially unwanted program, is included in the download bundle.
This software marketing technique is widely used by malware creators. The best way to avoid getting an unwanted bundle is by customizing the download settings on the installer UI instead of going for the default. By doing so, other inclusions to the package will be displayed and the choice to opt out from those items.
False Security Alerts on MacBook Air
There is a kind of a destructive software that is quickly rising nowadays. In order to remain vigilant against their attacks, users should know how it works. While using a MacBook Air, a hoax security program starts checking the system for unwanted activities and items then sends an alarming report that there are several issues found that requires an immediate action. These alerts are used to create panic to the user to remove the problem by accepting to pay for the license of the fake software.
Browser Hijackers on MacBook Air
This type of malware that targets MacBook Air first takes control of the installed browsers on the device like Safari, Mozilla Firefox, and Google Chrome. It changes the default startup page to their own main web page or redirects the user to a certain landing page even while browsing the user’s regularly visited sites.
Sometimes the user may suddenly encounter a deceptive website by just launching the browser, searching the web, or adding a new tab. It has a specific URL which is designed to show information to manipulate the user’s browsing behavior.
The most notorious example of this kind of hijacker is the alert page that displays the message “Your Mac is infected with 3 viruses!” It tries to brainwash the user that the MacBook Air is infected by a malware and that the user should immediately choose to “Scan Now.” However, by doing so, it only leads the user to another harmful cargo.
Adwares on MacBook Air
Another kind of threat to browsers installed on MacBook Air are the embedded persistent ads found on website pages. These ads are made by a type of malware called an advertising-supported software. They aren’t as infectious enough to spread throughout the system, but it becomes too annoying that it disrupts regular browsing habit.
Adware viruses can infiltrate almost all websites opened on an infected MacBook Air by showing multiple popups, banners, in-text links, coupons, shopping offers, and others. To make it worse, some of the regularly visited webpages are infested with an invisible layer so that when the user clicks on any part of it, the whole page is covered by a full-screen advertisement.
Because of this, there are already several windows that are opened without the user knowing it. This activity consumes CPU power which is needed for other dormant tasks. Adware viruses usually pushes its way through the Mac OS with the help of installed free software filled with snares, just like hijackers.
Ransomware on MacBook Air
Although ransom software isn’t a big deal among MacOS devices, it has been undergoing upgrades and modifications to become large enough to hack into the system. FBI ransomware viruses, or police viruses are not actually Trojan types because it only affects browsers and the quickest way to deal with them is by resetting the infected browser.
However, another type of ransomware called the KeRanger virus which was discovered on March 4, 2016 by Palo Alto Networks, is so much more dangerous because it wildly infects the MacOS to encrypt private data on an infected MacBook Air by using asymmetric cryptography then leaves a ransom message which demands for Bitcoins in exchange for the RSA decryption code.
Fortunately, this kind of virus has never been massively distributed, and their cipher is usually unrefined and has several bugs. Still, blackmailing viruses and other ransomware nowadays are way too obviously focusing their aim on Mac devices including the MacBook Air.
