How To Choose The Best Mac Antivirus For You
Choosing the best Mac antivirus for you is not to be taken lightly. You cannot simply go with the most convenient option because it’s cheap or it’s what your friend is using. The protection you need might be, after all, different from others.
The first thing you need to decide is how much you’re willing to spend on a subscription or if you’re willing to spend any money at all. It’s worth remembering that while free antivirus products are effective at protecting against threats, they also lack certain premium features.
If you have multiple systems on your network, for example, you’re at a higher risk of cyberattacks. More users means more endpoints to target. Additional management tools, typically available behind a paid subscription, let you set policies can help mitigate this risk.
Speaking of which, you do need to consider all the security features you need, from basic ones like real-time protection, parental controls and a password manager to access to secure VPN and dark web monitoring.
Finally, you need to find out just how big of an impact the antivirus software you’re considering has on your system. Some of them take up considerable bandwidth, which can be taxing on your computer especially if you’re regularly performing taxing tasks.

Dont Use Any Passwords And Change Them As Soon As You Can
From the moment you suspect you have a virus you shouldnt type any passwords or login details in case a hidden keylogger is running. This is a very common component with malware.
Beware that many keylogger-based malware or viruses also periodically secretly take screenshots, so be careful not to expose any passwords by copying and pasting from a document, for example, or by clicking the Show Password box that sometimes appears within dialog boxes.
Once you are free of the virus you should change all your passwords, and we really do mean all of them including those for websites, cloud services, apps, and so on.

Do Macs Need Antivirus Software
Most antivirus experts agree that while Apples security software is fairly good, its not foolproof. XProtect does not identify as many types of potential malware as third-party antivirus software, and gaps in its library of malicious programs can leave users exposed.2 Part of the problem is that the software relies heavily on Apple identifying and tagging malware and viruses, and since Apple isnt a dedicated security company, it doesnt keep track of nearly as many threats as third-party products. According to Malwarebytes, the number of serious malware attacks identified on Macs increased by 61 percent from 2019 to 2020, while less malicious adware rates declined, a worrying trend that suggests installing dedicated antivirus software is a wise decision.3 That being said, its important to make sure the antivirus you choose works on a Mac, which is why we tested the software we listed as the best antivirus software for Macs.

Three Layers Of Defense
Malware defenses are structured in three layers:
1. Prevent launch or execution of malware: App Store, or Gatekeeper combined with Notarization
2. Block malware from running on customer systems: Gatekeeper, Notarization, and XProtect
3. Remediate malware that has executed: XProtect
The first layer of defense is designed to inhibit the distribution of malware, and prevent it from launching even oncethis is the goal of the App Store, and Gatekeeper combined with Notarization.
The next layer of defense is to help ensure that if malware appears on any Mac, its quickly identified and blocked, both to halt spread and to remediate the Mac systems its already gained a foothold on. XProtect adds to this defense, along with Gatekeeper and Notarization.
Finally, XProtect acts to remediate malware that has managed to successfully execute.
These protections, further described below, combine to support best-practice protection from viruses and malware. There are additional protections, particularly on a Mac with Apple silicon, to limit the potential damage of malware that does manage to execute. See Protecting app access to user data for ways that macOS can help protect user data from malware, and Operating system integrity for ways macOS can limit the actions malware can take on the system.
