Antivirus software helps protect your computer against malware and cybercriminals. Antivirus software looks at data — web pages, files, software, applications — traveling over the network to your devices. It searches for known threats and monitors the behavior of all programs, flagging suspicious behavior. It seeks to block or remove malware as quickly as possible.
Antivirus protection is essential, given the array of constantly-emerging cyberthreats. If you don't have protective software installed, you could be at risk of picking up a virus or being targeted by other malicious software that can remain undetected and wreak havoc on your computer and mobile devices.
If you already have antivirus software, you may believe you're all set. But it might not be that simple. With new and savvier cyberthreats and viruses surfacing, it's important to stay current with the latest in antivirus protection.
If there's any crack in your cybersecurity defenses, cybercriminals likely will try to find a way in. Ensuring your antivirus software is up and running, and up-to-date, is a good place to start. However, hackers, scammers, and identity thieves are constantly tweaking their methods, so it's a good idea to get protection from a comprehensive security solution.
What is antivirus software designed to do?
What exactly is antivirus software designed to do? We're talking about a program or umbrella of programs whose purpose is to scan for and eradicate computer viruses and other malicious software, also known as malware. Antivirus software is a vital component of your overall online and computer security strategy in its protection against data and security breaches along with other threats.
When looked at simply, a computer virus is similar to a cold virus. It's designed to go from one computer or device to the next, copying itself, and spreading malicious codes and programs that can damage and infiltrate your operating systems. Viruses are designed to give criminals access to their victims' devices.
These viruses, spyware, and other malicious software are known as malware, and can be surreptitiously installed on your computer or device. Malware can do everything from crashing your device to monitoring or controlling your online activity. This control may enable hackers to send spam and steal your private information, which could eventually lead to identity theft.
Antivirus software provides protection against these types of threats by performing key tasks:
Free Antivirus For Mac Downloads
- Pinpointing specific files for the detection of malicious software
- Scheduling automatic scans
- Scanning either one file or your entire computer at your discretion
- Deleting malicious codes and software
- Confirming the safety of your computer and other devices
As cybercrime evolves and becomes more sophisticated, whether it's your own PC or other devices on a larger network, you don't want to leave yourself or your network vulnerable. If you don't have security software, you could be opening the door for cybercriminals to gain access to your most sensitive information — and potentially garner control over your computer and mobile devices.
What are the different types of antivirus protection?
Several types of antivirus programs have evolved over the years. When setting up your umbrella of protection, it's important to understand the more common antivirus programs available.
Malware signature antivirus
Malware, or malicious software, installs viruses and spyware on your computer or device without your knowledge. Malware can steal your login information, use your computer to send spam, crash your computer system, and essentially give cybercriminals access to your devices and the information stored on them, and even the ability to monitor and control your online activity.
Malware signature antivirus software detects malware signatures, which are digital fingerprints of malicious software. Antivirus protection can scan for specific malicious codes, identify specific viruses, and disable these programs.
While malware signature antivirus protection is key for detecting and eradicating known viruses, one limitation is its inability to address new viruses. The antivirus product simply doesn't contain these new virus signatures.
System monitoring antivirus
This is where system monitoring antivirus software comes into play. This antivirus protection can monitor software and computer systems for behavior that is suspect or atypical of the user.
For instance, alerts are created when a user connects to unfamiliar sites or attempts to access a large number of files, or when there's a significant increase in data usage.
Machine learning antivirus
Another form of protection can be machine learning techniques, which monitor 'normal' computer or network behaviors. The machine learning antivirus software is able to limit activities by programs or computers if they look suspicious.
More specifically, machine learning detection implements algorithms to facilitate malware detection that is broader in scope. This type of antivirus protection is beneficial because it works in tandem with other antivirus applications to provide multiple layers of protection.
One example of machine learning is the design of Microsoft's latest antivirus software, which can gather data from more than 400 million computers running on Windows 10 to discover new malware. (Note: To be clear, this is diagnostic data that a consumer can opt out of reporting.) This, in turn, takes us back to the importance of signatures, as this intelligence will allow for the development of new signatures for the latest malware discovered. This automation is key in its ability to stay on top of the latest viruses.
What does antivirus software help protect us from?
The beauty of malware for hackers is its ability to gain access to or damage a computer without our knowledge. It's important to be aware of the many different types of malicious codes, or 'malware,' against which antivirus software is designed to protect:
- Spyware: stealing sensitive information
- Ransomware: extorting money
- Viruses
- Worms: spreading copies between computers
- Trojans: promising one thing but delivering another
- Adware: advertising
- Spam: spreading unwanted email
Isn't Windows Defender enough?
Starting with Windows 8, Windows has built-in antivirus protection known as Windows Defender that is enabled by default. But is it enough? The answer is 'maybe' in that its efficacy isn't certain due to its reliance on several moving parts.
For instance, Windows Defender is a good defense against traditional viruses. But it may not detect threats beyond regular viruses, and may not protect your devices against more sophisticated infiltrations such as ransomware. So its effectiveness also depends on how careful you are as an individual. Are you going to click on that link or email attachment from an unknown sender or website? In order to be safe, you likely need an added layer of protection.
Do I need antivirus protection for Mac?
While Macs and other Apple devices may not be as frequently targeted as Windows computers, it's still a good idea to get additional antivirus protection to be ready for what may come in the future. At the moment, if you're careful about what you open, don't click on unknown links or attachments, and are careful in your online activity, you may be safe. But is it an unknown risk you're willing to take? 'Safe for now' may transition to 'no longer safe.'
Free antivirus software: Does it work?
Another common question is whether free antivirus software protects us. But is anything ever really free? 'Free' antivirus inevitably supports and makes money with advertising and tracking, and by installing junkware.
Free downloads also can hide malware. If you go this route, only download software from sites that you absolutely trust. You also must ensure that your security setting is set high enough to detect malicious codes.
Another thing to keep in mind when considering whether to rely on free antivirus protection? Identity theft protection, mobile security, and data security support options. These important security features often are lacking with free software.

Apple M1 chip.
A shared architecture for security.
The Apple M1 chip with built-in Secure Enclave brings the same powerful security capabilities of iPhone to Mac — protecting your login password, automatically encrypting your data, and powering file-level encryption so you stay safe. And the Apple M1 chip keeps macOS secure while it's running, just as iOS has protected iPhone for years.
Apple helps you keep your Mac secure with software updates.
More News For What Is The Antivirus Software For Mac
The best way to keep your Mac secure is to run the latest software. When new updates are available, macOS sends you a notification — or you can opt in to have updates installed automatically when your Mac is not in use. macOS checks for new updates every day and starts applying them in the background, so it's easier and faster than ever to always have the latest and safest version.
Protection starts at the core.
The technically sophisticated runtime protections in macOS work at the very core of your Mac to keep your system safe from malware. This starts with state-of-the-art antivirus software built in to block and remove malware. Technologies like XD (execute disable), ASLR (address space layout randomization), and SIP (system integrity protection) make it difficult for malware to do harm, and they ensure that processes with root permission cannot change critical system files.
Download apps safely from the Mac App Store. And the internet.
Now apps from both the App Store and the internet can be installed worry-free. App Review makes sure each app in the App Store is reviewed before it's accepted. Gatekeeper on your Mac ensures that all apps from the internet have already been checked by Apple for known malicious code — before you run them the first time. If there's ever a problem with an app, Apple can quickly stop new installations and even block the app from launching again.
Stay in control of what data apps can access.
Apps need your permission to access files in your Documents, Downloads, and Desktop folders as well as in iCloud Drive and external volumes. And you'll be prompted before any app can access the camera or mic, capture keyboard activity, or take a photo or video of your screen.
FileVault 2 encrypts your data.
With FileVault 2, your data is safe and secure — even if your Mac falls into the wrong hands. FileVault 2 encrypts the entire drive on your Mac, protecting your data with XTS-AES 128 encryption. Mac computers built on the Apple M1 chip take data protection even further by using dedicated hardware to protect your login password and enabling file-level encryption, which developers can take advantage of — just as on iPhone.
Designed to protect your privacy.
Online privacy isn't just something you should hope for — it's something you should expect. That's why Safari comes with powerful privacy protection technology built in, including Intelligent Tracking Prevention that identifies trackers and helps prevent them from profiling or following you across the web. A new weekly Privacy Report on your start page shows how Safari protects you as you browse over time. Or click the Privacy Report button in your Safari toolbar for an instant snapshot of the cross-site trackers Safari is actively preventing on that web page.
Automatic protections from intruders.
Software to cut music free download. Safari uses iCloud Keychain to securely store your passwords across all your devices. If it ever detects a security concern, Password Monitoring will alert you. Safari also prevents suspicious websites from loading and warns you if they're detected. And because it runs web pages in separate processes, any harmful code is confined to a single browser tab and can't crash the whole browser or access your data.
Find your missing Mac with Find My.
The Find My app can help you locate a missing Mac — even if it's offline or sleeping — by sending out Bluetooth signals that can be detected by nearby Apple devices. These devices then relay the detected location of your Mac to iCloud so you can locate it. It's all anonymous and encrypted end-to-end so no one — including Apple — knows the identity of any reporting device or the location of your Mac. And it all happens silently using tiny bits of data that piggyback on existing network traffic. So there's no need to worry about your battery life, your data usage, or your privacy being compromised.
Keep your Mac safe.
Even if it's in the wrong hands.
All Mac systems built on the Apple M1 chip or with the Apple T2 Security Chip support Activation Lock, just like your iPhone or iPad. So if your Mac is ever misplaced or lost, the only person who can erase and reactivate it is you.
