No paid Mac antivirus program stands out in reviews as better than the free Avast for Mac. Last year's winner, Bitdefender Antivirus for Mac (Est. $50 per year for 3 Macs), still sails through tough tests at AV-Test and AV-Comparatives, flawlessly slaying both Mac and Windows malware. Avast one of the best world top popular security software and like to use anyone. Avast all products like Avast Free Antivirus, Internet Security, Avast Pro Antivirus and Premier offline installer free download for Windows and Mac. Avast comes with a variety of protection products which it needs for your device.
While it's unlikely you'll ever run into malware for the Mac, you may want to consider an antivirus tool anyway—if not to protect yourself, but to protect your Windows-using friends from any malware you may inadvertently send their way. We think that Sophos Anti-Virus for Mac is the best choice, and it's free.
Avast Free Mac Security
Avast Security (for Mac) delivers effective malware protection along with unusual bonus features. Phishing protection only works well in Chrome and Firefox, but this free utility is still worth a.
Update: Our previous recommendation for Mac Antivirus was 'nothing.' We know many of you choose to use nothing, but we also know you don't come to the App Directory to not get any suggestions at all. Besides, malware is starting to become a bit more prevalent on the Mac, and even the safest browsing habits don't protect you completely. So, we now officially recommend Sophos as our Mac antivirus of choice.

Features
Avast For Mac
- Compact, easy-to-use interface that can be used for custom on-demand scans of files, folders, and drives, or scheduled, periodic full scans of your Mac.
- Also scans files on your Mac for known Windows malware, trojans, and viruses, and deletes or quarantines them so you don't risk spreading them to someone else via network share, USB drive, or email.
- Deletes or quarantines known threats, gives you the option to quarantine anything suspicious that may be a new threat or dangerous file.
- Runs quietly in the background, scanning emails, downloads, and any other files on access, stopping you from opening them before they can do any harm.
- Light on system resources while running in the background.
- Installs like any other Mac application, and uninstalls just as easily—no complicated packages or components to manage or configure.
- Sophos' 'Live Antivirus' feature updates your app the moment new threats are detected or found in the wild. The feature also performs real-time lookups to see if files accessed are in the SophosLabs database, even if they're unfamiliar to the app.
- Supports OS X up to 10.8 and back to 10.4, and is completely free for all versions.

Where It Excels
Sophos actually has an excellent breakdown of the history of malware for the Mac going all the way back to 1982. The fact that the article exists should remind Mac users that while they're not the primary target for malware authors, they're by no means invulnerable. The size of the article however should issue some confidence that the risk—while present—is by no means critical.

Sophos Anti-Virus for Mac stands out in a somewhat crowded field of Mac antivirus apps because it doesn't just scan your Mac's files and folders on demand, but it does it quietly in the background without tapping your already precious system resources in the process. The utility also keeps its own constantly-updating database of Windows viruses, trojans, and other threats, so if you inadvertently download a Windows virus or trojan that won't harm you, you don't run the risk of sending it off to someone else by forwarding the message, or you won't infect other computers on your network (or any Windows partitions or virtual machines you run on the same hardware) via shared drives. Sophos is smart enough to tell you 'Hey, this won't hurt you, but we're going to quarantine/delete it so you don't accidentally email this attachment to someone else.' That's a huge benefit—and it keeps you from being that guy no one likes.
Another banner feature Sophos offers that its competition doesn't is its live, real-time access to SophosLabs. 'Live Antivirus,' as it's called in the app, gives you an added layer of protection. The app automatically identifies and quarantines suspicious files, installers, and other packages that may not be well known threats yet, but definitely exhibit behavior suspicious enough that Sophos is looking into them.

Best of all though, in our testing, Sophos was one of the most resource-light antivirus apps on the Mac, which is impressive considering the features it offers.
Where It Falls Short
Sophos Anti-Virus for Mac isn't perfect, however. Even though it's pretty resource light, it wasn't the lightest in our tests. It just hit the sweet spot between resources and features. Also, support for Mountain Lion came a few months after its launch, so Sophos wasn't exactly right there with those people who upgraded on launch day.

The Competition
ClamXav 2 uses the open source ClamAV virus scanning engine. It can also detect both WIndows and OS X malware, scan on demand or on a regular schedule, and it's probably a bit more lightweight and easy on system resources than Sophos. It's compatible with OS X 10.5 or higher. The only trouble with ClamXav is that its definitions come a bit more sporadically than we'd like (daily, usually, sometimes, if they feel like it) and while performing scans is easy, tweaking all of the settings and getting the app scanning proactively is a little more effort than I'd like to see. Still, it's an excellent alternative, and one of the first you should check out if Sophos isn't cutting it for you.

Avast! Free Antivirus for Mac is the Mac version of our current favorite for Windows, and for good reason. The researchers at AV Comparitives found that Avast detected 100% of the Mac malware that went through it, an honor that few other utilities won (they didn't test Sophos, unfortunately). It's free, it works, it's lightweight, but the only catch is that it only scans for Mac-specific malware, which won't matter to you if you're in an all-Mac ecosystem, but if you, like most of us, share the world with Windows users, thinking of them doesn't hurt.
Avira is another free utility worth a look. It also picked up 100% of the Mac malware that passed through it with no false positives. Avira's UI and options are perfect for non-technical users, and it offers strong protection against known Mac threats. Again, there's no Windows protection in the app, and both the scheduling and custom scan options are a bit anemic, so power users may want to shy away from it. If you're installing it on your non-technical friend or family-member's Mac however, it's a great option.

We're not trying and settle the antivirus-versus-no-antivirus debate; it's been raging for years and isn't going to stop now. For a great and thorough perspective on the issue, check out my old colleague Neil Rubenking's take at PC Mag's SecurityWatch blog, and The Safe Mac's approach to the topic.

Whatever you do though, it's probably not necessary to plop down money for a Mac antivirus suite. The threats don't warrant you dropping money on software to keep you safe, and too many of them do more harm than good (especially the ones looking to get your money). They're just not worth it, especially when there are more effective, robust, free options like the ones above available to you.
First things first: yes, your Mac needs virus protection. While malware that targets Macs isn't nearly as common as malware that goes after Windows, it does exist and is a growing problem.
Viruses specifically may not yet be the major concern for the Mac but there are many different kinds of malware to worry about: things like trojans, adware, ransomware, spyware, and lots of other dangerous wares so keeping your computer protected is smart.
Our advice? If you're not using an antimalware program for Mac yet, it's time! Below you'll find the 4 best ones we've found, any of which will keep your Mac safe from these growing threats.
If you're here because your Mac is already infected with some form of malware, try using a friend's Mac to create an emergency Mac OS boot device and then use that to download and install one of these antivirus apps to detect and remove the suspected malware.

Avast Free Mac Security uses a traditional signature-based method to scan files on your Mac for known malware, Trojans, and viruses. Avast can root out rootkits and other methods that a hacker uses to gain control and is able to pry open compressed files to scan their content.
Beside malware designed for the Mac, Avast also looks for PC malware to help keep cross-platform infections from occurring. You don’t want to be the person sending off infected email attachments to your PC friends.
Avast uses real-time detection that runs in the background. Avast, like other antivirus apps that continually run in the background, can have an impact on your Mac's performance. Avast, however, gives you the option of using its real-time detection, or a scheduling system that can have less impact on your Mac's performance.
- Scheduled scans allow you to set the time for Avast for Mac to run its routine scans for the presence of malware. Moving the scheduled time to when it will least impact your workload is a big plus.
- File shield can check all of the files on your Mac for nefarious content. Files can also be checked by file type or location on your Mac.
- Web shield blocks unsafe websites from loading or downloads from those sites from occurring.
- Mail shield prevents dangerous email attachments from downloading or from being executed.
- Local network scan makes sure your home network and all connected devices are free from vulnerabilities that hackers could make use of to steal personal data.

Bitdefender Antivirus for Mac
What We Like
Easy to set up and forget about.
Finds malware automatically.
Includes lots of really great features.
Has a lightweight footprint.
What We Don't Like
The free version is limited in several important ways.
Bitdefender offers two security apps for the Mac a free Virus Scanner for Mac and the paid Bitdefender Antivirus for Mac. Both use the same Bitdefender engine for finding and removing malware, but Virus Scanner for Mac uses a manual approach to scanning your Mac, while Bitdefender Antivirus for Mac is loaded with features to make the process simple and, if you want to, as automatic as possible to ensure you are never the victim of a malware attack.
In fact, the Autopilot feature works so well that you can just about turn it on and forget about it, knowing that your Mac is protected from current and future threats from malware as well as ransomware, which is on the upswing in the hacking world.
- Time Machine Protection monitors your Time Machine backups and prevents ransomware attacks that may try to encrypt or remove your backups.
- Safe File allows you to specify folders that will be continuously monitored, preventing unauthorized apps from making changes to these folders.
- Adware removal can free your Mac from annoying ads, unwanted browser add-ons, and browser toolbars that may be added without your consent.
- Traffic Light browser extension works with Safari, Chrome, and Firefox to add advance phishing detection to your browser and warn you of dangerous websites.
Bitdefender makes use of traditional signature-based detection system as well as behavioral-pattern recognition. To help keep its database of devious malware types up to date, Bitdefender uses a cloud-based data collection system that stores the most recently detected Mac malware, adware, and ransomware information, allowing all Bitdefender users to have the latest updated detection system.
Malwarebytes for Mac
What We Like
It's always active and running to find threats.
Provides advanced options that can be tweaked to your desires.
Doesn't use up lots of memory or CPU.
What We Don't Like
The free version only works in manual mode (i.e., it can't catch malware automatically).
Malwarebytes for Mac has been a top choice for finding and removing Mac-based malware ever since its early appearance as Adware Medic.
Now under the guidance of Malwarebytes, the app retains its free ability to find and remove malware but has also expanded its capabilities to offer a premium paid version that can actively prevent Mac virus, spyware, and malware infections. It can also keep adware and unwanted apps from finding a home on your Mac.
- Detects and removes adware targeting Macs without requiring a separate browser add-on.
- Real-time protection can be disabled, allowing you to scan only when you wish.
- Includes an uninstaller for removing the Malwarebytes app.
- Low system overhead even with background scanning enabled.
Malwarebytes uses a signature-based system to determine the presence of Mac malware. The signature list can be updated as often as once per hour. Malware that is discovered can be automatically quarantined for easy removal at a later date.
Sophos Home for Mac
What We Like
Provides real-time threat detection.
Identifies and removes various types of malware.
Includes unique features such as remote management.
Protects against web threats via filtering.

- Remote management allows you to monitor, configure and control Sophos Home on up to ten Macs or PCs.
- Parental controls can block viewing inappropriate websites while keeping a log of such web visit attempts for later review.
- Background scanning had a low impact on overall performance.
- On-demand scanning allows you to initiate a scan at any time.
Avast For Mac Review
Sophos runs primarily in the background scanning your Mac and detecting if malware or related threats are present whenever you download, copy, or open a file or folder. The scanner can also examine compressed files to make sure files contained within are safe.
