Computers have become one of the main tools for modern people to work, study, and entertain. In today's environment, the computer camp has basically been divided between two companies, namely Microsoft's Windows computers and Apple's macOS computers. In the eyes of many people, Mac computers are less likely to be attacked by viruses than Windows computers. This is related to the closure of computer systems, but the core key is that the current market share of Windows computers is much larger than that of Mac computer products.
Most computer users use the word "virus" to refer to any form of malware. Therefore, the root cause of viruses is actually our irregular downloading of software and browsing some phishing websites. If you don't operate a brand-new computer for two or three years, then according to common sense, no viruses will be generated. Compared with Windows computers, Mac computer products do have ways to block some malware, spam, phishing emails, browser vulnerabilities, identity theft, etc. This is because the entire macOS system is under Apple's surveillance. The Windows system seems to be more "accommodating", both of which have their own advantages and disadvantages.
Previously, Apple Senior Vice President Craig Federighi said: The amount of malware on macOS has reached a level that is officially unacceptable to Apple. Although Apple invests significant resources in strengthening security and privacy on Macs, some types of malware and viruses are sophisticated enough to bypass the Gatekeeper protection system. In addition, the editor also learned from data from foreign media Malwarebytes that the peak number of macOS-specific malware infections has increased by 200% in recent years. So the question is, does a Mac computer really need anti-virus software? How should we protect our computer systems? Today the editor is here to discuss this problem with you.
macOS system
macOS is a system developed based on Unix. Compared with the Windows system, not only the running environment is relatively closed, but also the system has fewer vulnerabilities. Most viruses that are effective on the Windows system are not effective on the macOS system. At the beginning of the article, the editor said that the macOS system is under Apple's surveillance and the system is updated frequently. In fact, you can understand that every system update is an official anti-virus by Apple for the user's computer.
In addition, there is a real-time activity monitor on macOS computers. If there is something strange or dangerous on the user's computer, it will be displayed on the monitor. You can choose to check the application or uninstall it directly. But this operation is relatively troublesome. First, we need to open the finder, select the application section, and then find the corresponding folder to find the activity monitor. Then we find the problematic application in Activity Monitor and close or uninstall it.
Although this method seems complicated, it is actually simple to operate. Many users have to invest more time in order to get the best malware removal results. After Activity Monitor removal, the parts of the virus application are still scattered in your system folders. You need to find them in Finder and then Delete completely bit by bit. It's a bit like cutting off a lizard's tail, it just takes a while to grow back after you cut it off, so we need to remove it thoroughly!
Relatively closed application
Computers equipped with macOS are the same as iOS iPhones. All software needs to be downloaded from the App Store. If users only allow apps from the Mac App Store to be on their computers, then your computer will most likely not encounter virus attacks. This is because all app developers in the Mac App Store have been officially recognized by Apple, and each app is strictly inspected before being accepted on the store. In addition, the user's macOS system will check before the App is run for the first time to prevent the App from being modified after the developer released it.
But there are always exceptions. There are still many useful applications on Mac computers that have not been put on the Mac App Store (such as Adobe Family Bucket). MacOS computers can download many third-party applications on the Internet. We need to turn on the system settings to allow apps from the Mac App Store and recognized developers. Of course, the developers of these software are only approved by Apple and are not The former has a strict review process, so the risks are relatively higher.
How to tell if my Mac is infected with virus
Because the Mac system is closed, it will also lead to some bad phenomena. For example, it is difficult for users to detect whether their computer is infected? The editor here also gives you an introduction. Here are some signs that your Mac may be affected by viruses or malware: Mac computer restarts and freezes unexpectedly, sudden performance drop, applications start for no reason, browser pop-ups and An increase in the number of ads, new applications installed on the computer without the user's permission, and unexplained random changes to browser settings (such as search engine or home page).
Safe mode for Mac computers
If your Mac computer is infected, the system will run very slowly and cannot do anything. The editor also teaches you a trick that may be useful—start your Mac in safe mode. When you start your Mac computer in Safe Mode, the system automatically blocks certain software from loading and only runs essential applications and handles macOS needs. In addition, safe mode will also check the computer's startup disk and delete some unnecessary system cache, which may help your computer.
The specific startup method is as follows, Mac equipped with Intel chip: first restart the Mac and hold down the Shift key when the Mac starts; secondly, when the login window appears, release the Shift key and log in; finally, we can click on the upper right corner of the screen See "Secure Boot". Macs equipped with Apple M-series chips: First, restart the Mac and hold down the power button; secondly, when we see the startup options, please release the button to select the startup disk and hold down the Shift key, and then click "Continue in Safe Mode"; Finally, we chose to log in to Mac, but it may take a few more operations.
Protection suggestions
We can create a new user profile to confuse the virus. Typically, computer viruses attach themselves to specific user profiles on a user's computer, thereby taking control of the user's administrative profile. But we can avoid it and create a new user on the Mac. Of course, this method is not 100% effective. Moreover, you won’t have to worry about some important data as we can transfer all important data from one user to another at any time.
In addition, there is a way to kill one thousand enemies but lose eight hundred. We can prevent some malware attacks by disabling JavaScript in the browser. Although this method may disrupt browsing of some websites, it relatively improves the security of the system.
Many friends who pay attention to the software cleanmymac have asked, how about the software clcleanmymac? The cleanmymac software is still very good. It can smoothly combine with system performance to clean the junk cache in our computers. It is also very easy to use.
How about the software cleanmymac?

7.CleanMyMac is a mac cleaning software, it cannot kill viruses. What we are talking about here is the main function of this software. It does not mean that Mac OS It can be cleared so easily, so instead of wasting energy on developing a function that is extremely difficult to maintain, it is better to optimize other functions and truly achieve close to perfection.
8. What comes next is a very important question: download CleanMyMac. Those downloaded on the Internet are generally free trial versions, which have some limited functions and can only clean up 500MB of garbage. This is what we need to understand.

Finally, there are some simple protective common sense, such as carefully reading all dialog boxes when installing applications, finding a reliable password manager application (the one that comes with the system is good), and creating an "emergency" for our Mac. Bootable external drives, avoid clicking on suspicious email links (especially if you do not identify the sender), avoid downloading software or data from unfamiliar websites, do not open any suspicious email attachments, and more.
Summarize
In fact, the editor believes that Mac computers still need users to consciously protect them. Although there is no need for professional anti-virus software, it is best for users to install some applications that can quickly understand the status of the computer. It is also very simple to prevent computers from being "poisoned". As mentioned at the beginning, in macOS, a closed system, the main sources of viruses are unknown websites and third-party applications. Users only need to maintain good browsing habits and adhere to Downloading software from the Mac App Store is basically free of viruses.
