Types Of Malware & How To Remove Them In macOS

It is undeniable that macOS, the operating system (OS) made by Apple, does offer better security protection than other OS. However, macOS is not immune from malware attacks. Security firm Avast revealed that it had blocked more than 250 million malware threats targeting Mac users since January 2017.

“MacOS is not immune from malware attacks,” wrote Lukas Haisk, Avast’s senior product manager.

He added, “As safe as Macs are, the cyberattacks that hackers launch against macOS are increasing more than in previous years.”

This attack is increasing as more and more people in the world use Mac devices. Malwarebytes said the spread of malware on Mac in 2017 was higher than in previous years. With this report, it is possible that macOS has vulnerabilities in its firmware too.

Given the increasing attacks and spread of malware on macOS, we want to explain to you about the types of malware on MacOS and how to remove them.

What Is Malware

Malware is an extension of Malicious Software which is made to enter and hack a computer system, server or network without the knowledge of the owner or user of the computer device.

This software is intentionally created specifically to work illegally and covertly to damage the device, retrieve data without permission or steal, and cause damage to the software

This one software is indeed something that must be aware of for owners of computer equipment. This is because malware is directly related to the internet network, which is usually used by most users.

What’s more, nowadays, there are many activities that require an internet network, and malware is usually very easy to enter via the internet network. Hackers and crackers can always hack computers from a back door or can also be deliberately implanted on illegal sites to hack data.

The Types of Malware

After knowing some of the bad effects of malware, you also need to know some types of malware that you should be aware of. The following are types of malware.

1. Viruses

Viruses are a type of malware that can attach to files or documents on a computer device. This type of malware is designed to destroy user data or information when using and using documents.

As for the viruses, do you remember the Search Marquis virus? This one virus is quite troubling for so many MacOS users. But don’t worry, it can be avoided if you have a VPN. The VPN may work best if combined with the best, reputable antivirus software in removing search marquis no hassle. That way, your MacOS device will always be safe wherever you go. If you’re depending on using public internet connections a lot, VPNs can also protect you further from potential harm.

2. Trojans

Trojans are malware that usually disguises applications or software. This type of malware will work actively when a user downloads software that has been attacked by a trojan. When the user starts downloading, the trojan will quickly spread and start stealing various important user information.

One example of a terrible case that happened because of Trojan is the spreading of Shlayer. Shlayer itself is a trojan malware family which is the biggest threat to macOS users in 2019.

The criminals behind this malware use a clever distribution system that spreads through partner networks, entertainment sites, to Wikipedia. In this way, it can be concluded that users visiting legal sites can still be targeted by Shlayer.

Shlayer specializes in installing adware programs that terrorize users with prohibited advertisements. This malware collects user browser requests, and modifies search results to distribute more advertisements.

The actors behind Shlayer created a malware distribution system with a number of channels directing users to download malware.

3. Adware

One of the software that can display pop-up ads when the user clicks or takes certain actions. However, this adware is categorized as a type of malware that is not all dangerous. Even so, adware can damage system software by sending malware which is usually called spyware.

4. Worms

This worm has special skills as it can reproduce itself and then spread it to computer software. This worm can also enter from the internet network or applications installed by the user.

5. Ransomware

It’s that one type of malware that is quite dangerous because it is used to commit cybercriminals. Usually, hackers will ask for ransom after hacking and stealing user data using Ransomware. This malware is usually installed via email attachments, websites, and short messages.
