If you think Windows is the most susceptible to viruses, and your favorite MacBook is fully virus-protected, then we’re in a hurry to warn you, that’s not true. Yes, viruses are rarer here than on Windows, but they also exist on Macs .
But you are not helpless in the face of malware attacks. There are many ways to improve your protection. And if you are the losers few whose Mac computers are unintentionally exposed to annoying and dangerous viruses, then you have come to the right place.
This article will help you understand everything and react to a virus on your Mac.
What is malware?
The term “virus” is a short term for malicious programs that can take many forms. For example, a virus can be a special program developed by hackers that has been installed on your computer without your knowledge. Once infected, all files and documents will be blocked and in order to access them you will have to pay, in some cases, a substantial sum to the cybercriminal.
The other type of malware is adware . The adware is installed when you click on a regular advertisement (on a website or when you receive an email) and install the malware on your computer. Once installed, it can collect information including your bank details. One of the most problematic aspects of this type of malware is that it is often disguised as a cleaner or antivirus app , which is usually expected to remove malware on your Mac. It is therefore essential to identify and remove viruses quickly.
On Windows there are many free but also paid cleaning software . And while Macs are known to be much less sensitive, it is still quite possible that they may be infected with malware.
