In this guide, we'll explain these steps in more detail. We'll also explain why you need antivirus software, what it does, how much it costs, and the differences between free, basic, and premium. McAfee is a good antivirus and worth the investment. It offers an extensive security suite that will keep your computer safe from malware and other online threats. It works really well on Windows, Android, Mac and iOS and the McAfee LiveSafe plan works on an unlimited number of personal devices.

No, and if your bank insists you install some non-Apple product I recommend you find another bank, because any organization that does not understand such fundamental aspects of Internet security should not be trusted with your money. There appears to be an incestuous relationship between at least one 'anti-virus' product vendor and many banks. Their product is capable of nothing beneficial and is likely to prevent your Mac from working properly.

Technically, there should be no need for Windows 10 users to download a separate antivirus program. After all, Windows Defender has already been built into this operating system. This is already a legitimate protection plan to guard against security threats and viruses. However, it isn’t always that simple to make a decision, so here you can.
It’s not mandatory, but an ounce of prevention is worth a pound of cure. Mac does not require antivirus software, they are still vulnerable to other attack vectors, including email based phishing attacks or browser-based cross-site scripting or man-in-the-middle attack.

A much better question is 'how should I protect my Mac':

Never install any product that claims to 'speed up', 'clean up', 'optimize', or 'accelerate' your Mac. Without exception, they will do the opposite.
Never install pirated or 'cracked' software, software obtained from dubious websites, or other questionable sources. Illegally obtained software is almost certain to contain malware.
Don’t supply your password in response to a popup window requesting it, unless you know what it is and the reason your credentials are required.
Don’t open email attachments from email addresses that you do not recognize, or click links contained in an email:
- Most of these are scams that direct you to fraudulent sites that attempt to convince you to disclose personal information.
- Such 'phishing' attempts are the 21st century equivalent of a social exploit that has existed since the dawn of civilization. Don’t fall for it.
- Apple will never ask you to reveal personal information in an email. If you receive an unexpected email from Apple saying your account will be closed unless you take immediate action, just ignore it. If your iTunes or App Store account becomes disabled for valid reasons, you will know when you try to buy something or log in to this support site, and are unable to.
Don’t install browser extensions unless you understand their purpose. Go to the Safari menu > Preferences > Extensions. If you see any extensions that you do not recognize or understand, simply click the Uninstall button and they will be gone.
Don’t install Java unless you are certain that you need it:
- Java, a non-Apple product, is a potential vector for malware. If you are required to use Java, be mindful of that possibility.
- Disable Java in Safari > Preferences > Security.
- Despite its name JavaScript is unrelated to Java. No malware can infect your Mac through JavaScript. It’s OK to leave it enabled.
Block browser popups: Safari menu > Preferences > Security > and check 'Block popup windows':
- Popup windows are useful and required for some websites, but popups have devolved to become a common means to deliver targeted advertising that you probably do not want.
- Popups themselves cannot infect your Mac, but many contain resource-hungry code that will slow down Internet browsing.
- If you ever see a popup indicating it detected registry errors, that your Mac is infected with some ick, or that you won some prize, it is 100% fraudulent. Ignore it.
Ignore hyperventilating popular media outlets that thrive by promoting fear and discord with entertainment products arrogantly presented as 'news'. Learn what real threats actually exist and how to arm yourself against them:
- The most serious threat to your data security is phishing. To date, most of these attempts have been pathetic and are easily recognized, but that is likely to change in the future as criminals become more clever.
- OS X viruses do not exist, but intentionally malicious or poorly written code, created by either nefarious or inept individuals, is nothing new.
- Never install something without first knowing what it is, what it does, how it works, and how to get rid of it when you don’t want it any more.
- If you elect to use 'anti-virus' software, familiarize yourself with its limitations and potential to cause adverse effects, and apply the principle immediately preceding this one.
- Most such utilities will only slow down and destabilize your Mac while they look for viruses that do not exist, conveying no benefit whatsoever - other than to make you 'feel good' about security, when you should actually be exercising sound judgment, derived from accurate knowledge, based on verifiable facts.
Do install updates from Apple as they become available. No one knows more about Macs and how to protect them than the company that builds them.

Summary: Use common sense and caution when you use your Mac, just like you would in any social context. There is no product, utility, or magic talisman that can protect you from all the evils of mankind.

You may have been led to believe that you don’t have to worry about computer viruses on your Mac. And, to some extent, there’s truth to that. While your Mac can definitely be infected with malware, Apple’s built-in malware detection and file quarantine capabilities are meant to make it less likely that you’ll download and run malicious software.

Apple introduced malware detection to the Mac OS with Snow Leopard (Mac OS 10.6). This system consists of the quarantine of any app downloaded from the Internet, the use of Code Signing certificates to verify that an app is coming from a legit source, and regular security updates that include databases of known malware targeting the Mac OS.

Because of this system, called File Quarantine and occasionally referred to as XProtect:

Apps in quarantine display a dialog window reminding you where the app came from and asking whether or not you’re sure you want to open it.
Apps with no code signing certificate, depending on your Gatekeeper settings, may display a message saying the app can’t be opened because of your settings. (For software you know is good you can bypass this by control-clicking the app and selecting Open from the resulting contextual menu.)
Apps that are known malware cannot be opened at all. You’ll be met with a message offering the option to toss the app in the trash.

And this is why Macs remain mostly virus and malware free.

To make sure your Mac malware database is always up to date you’ll want to verify that your Mac always automatically installs security updates and related system data files.

To do this:

Open System Preferences
Open the App Store preference
Make sure that Automatically check for updates and Install system data files and security updates are checked.

This should keep your Mac free from most malicious software, although i
