Read on for a quick summary of the best choices for free antivirus software for 2020.

Avast Free Antivirus

One of the oldest antivirus companies, Avast has been protecting users since 1988 and is trusted by millions of people around the globe.

Essential protection: Avast Free Antivirus consistently ranks extremely high for its core protection engine. Top antivirus test lab AV-Comparatives named Avast Product of the Year 2018 and Top-Rated Product in 2019, in addition to giving Avast awards for Malware Protection and Advanced Threat Protection. Avast continues to support Windows 7, even though Microsoft has stopped updating the operating system.

Features: Offering an easy-to-use interface, a secure web browser, a network security scanner, and more, Avast has a host of useful bonus features. Lifewire praises its Do Not Disturb Mode, which blocks pop-ups while you watch a movie or play a game, so you aren’t interrupted. Lifewire also highlights the Behavior Shield, which keeps an eye on your apps to make sure they don’t start to act strangely, a potential sign of a malware infection.

Need a second opinion?TechRadar notes that several special features are only available in Avast’s paid version. However, they still rate it as “a powerful antivirus which offers solid all-round protection. Experienced users will appreciate its lengthy feature list and the fine control they get over how the package works.”

AVG AntiVirus FREE

One of the pioneers of the free antivirus app, AVG has consistently won awards from AV-Comparatives over the past decade — including Top-Rated Product in their most recent test.

Essential protection:PCMag praised AVG AntiVirus FREE for achieving very good scores in a variety of independent tests, and for its excellent protection against phishing. AVG’s on-demand scan searches for hidden malware, which includes viruses as well as other sneaky malicious software such as spyware and ransomware. AVG also scans for malicious URLs, unwanted browser add-ons, and PC performance issues. AVG protects against 0-day threats by preventing unknown (and potentially dangerous) files from opening, and then sends these files to AVG Threat Labs for deeper analysis. If they’re found to be malicious, a cure is created and pushed out to you and all AVG users.

AVG continues to protect Windows 7, even though Microsoft is no longer supporting it.

Features: AVG AntiVirus FREE offers several bonus features, including a free File Shredder to securely delete sensitive files and prevent your personal data from being exposed. PCMag noted that, although AVG scans to find junk files and clutter that are slowing down your device, you’ll need to purchase AVG TuneUp to fix the problems.

Need a second opinion? In its review “8 of the Best Free Antivirus Software Options,” Mashable noted that AVG AntiVirus FREE has the most accurate virus detection, saying, “AVG AntiVirus FREE is near flawless with its ability to detect viruses and malware. It's unlikely anything is getting through this.”

Avira Antivirus

Avira has been creating antivirus applications for a long time, with the first one dating back to 1986.

Essential protection: While PCMag awarded Avira Antivirus a good score in their malware blocking test, they also found the on-demand scan slow and cautioned that its “real-time protection missed some malware EXEs and identified some valid programs as malware.”

Features: Avira’s free version is light on features. Safetydetectives.com notes that Avira’s focus is “on protecting computers without the bells and whistles.”

Need a second opinion? Tom’s Guide says, “Avira Free Antivirus has a heavy system load while providing only so-so malware protection.”

Bitdefender Antivirus Free Edition

Bitdefender protects half a billion users around the world and snagged the top spot this year from AV-Comparatives.

Essential protection: TechRadar praises Bitdefender’s “clean, light, well constructed scanning mechanisms – which are almost universally faster than the industry average – and unrivalled virus definitions.” But they also note that the product “grabs more resources than average, and might conflict with some programs.”

Features: PCMag says that “Bitdefender Antivirus Free Edition includes the core malware-fighting components of Bitdefender's commercial edition, but without the vast collection of additional security features, and without some advanced layers of malware protection.' CNET notes that “Bitdefender Antivirus Free is refreshingly free of the ‘extra’ features and tools that make some apps unwieldy and confusing.”

Need a second opinion?DigitalTrends mentions that “the application features no configurations of any kind,” while TechNadu adds that “its minimalistic design ensures the app retains only the bare essential antivirus functionality monitoring the system in real-time without needless embellishments.”

Kaspersky Security Cloud Free

Russian cybersecurity company Kaspersky has faced allegations of inappropriate connections to the Kremlin, prompting the US, the UK, and The Netherlands to ban the use of Kaspersky products across government agencies. Nevertheless, the allegations remain inconclusive and Kaspersky is consistently a top-rated product.

Essential protection: Kaspersky Free has earned excellent marks in independent test labs, including good scores on PCMag’s malware-blocking and malicious URL blocking tests and a perfect score on their phishing test.

Features: TechRadar says that Kaspersky is “short on advanced features and most of its extras are very limited, but you still get all the core antivirus essentials.”

Need a second opinion? A Tom’s Guide review found that “Kaspersky Free Antivirus delivers excellent protection with a moderate performance impact, but it has few extra features.”

Microsoft Windows Defender

Windows Defender is Microsoft’s built-in antivirus, which is included for free in Windows 10. If this app is already on your PC, you might be wondering why you should even bother with a free third-party antivirus. Short answer: Because many experts say Windows Defender still isn’t as good as the leading antivirus programs.

Essential protection: While Windows Defender traditionally ranked below third-party antivirus software, it’s now improved enough to claim the number six slot on PCMag’s annual top ten list. Its malware detection capabilities have risen greatly, and it performed well in hands-on testing. Still, PCMag is half-hearted in their recommendation:

“Windows Defender is improving, but you still shouldn’t rely on Windows 10’s security tools as your sole means of protection. Many free third-party apps are more effective at keeping you safe.” — Neil J. Rubenking, PCMag Best Free Antivirus Protection for 2020

Features: Windows Defender still lags behind in phishing protection and malicious URL blocking, and it can’t compete with the extra security features included in most free third-party security software.

Need a second opinion? Tom’s Guide gives Windows Defender a 3.5 out of 5, saying, “Defender's low system impact is offset by its long scan times and lack of creature comforts, such as the ability to schedule scans.”

Note for Windows 7 users: Microsoft's built-in security program for Windows 7 is Microsoft Security Essentials. The company will continue to support the antivirus software for the time being, but their overall support for Windows 7 has ended and they recommend you upgrade to Windows 10. If you remain on Windows 7, it’s more important than ever to protect your system with third-party antivirus software.

Sophos Home Free

Sophos Home Free comes from Sophos, which predominantly focuses on security solutions for businesses.

Essential protection: Sophos Home Free offers much of the same protection as their business products, including remote security management for up to three PCs or Macs. According to TechRadar, this means you can also install the free antivirus on a less tech-savvy family member’s computer and remotely manage their security for them. Sophos Home Free offers decent phishing protection and very good malicious URL blocking.

Features:PCMag found Sophos's parental content filter ineffective, but noted that, “If you're managing security for others, this product's remote management is a godsend.”

Need a second opinion?Cloudwards cautions that although Sophos has some nice features, most of them are only available if you upgrade to the paid version, and “rigorous testing sheds some doubts about its efficacy as an antivirus solution.”

Additional options

While they didn’t rank the highest this year, you may be wondering how these other popular free antivirus programs fared in expert reviews.

Adaware Antivirus Free 12

Adaware Antivirus Free comes from Adaware, a company formerly known as Lavasoft.

Essential protection: Adaware Antivirus Free has received mixed scores in independent tests, and it doesn’t provide any protection against malicious URLs. But, Lifewire notes that “constant, real-time protection against spyware, viruses, and other malicious items is important for any computer, and Adaware Antivirus Free can do just that.”

Features: Version 12 of Adaware’s free antivirus comes with a new look, but lacks features found in other free products — including the company’s own previous edition. Lifewire adds, “we don't think Adaware Antivirus Free should be your first choice when choosing a good antivirus program. There are too many settings in the program that would be useful but aren't allowed to function because it's just the free version.”

Need a second opinion?PCMag cautions that “Adaware Antivirus Free 12 has a new name and a new look. Under the hood, though, its test results aren't the best, and competing free products have much more to offer.”

Check Point ZoneAlarm Free Antivirus+

Check Point ZoneAlarm is a free antivirus-firewall combo that licenses its antivirus engine from security giant Kaspersky (see above for info on Kaspersky).

Essential protection: Pairing strong antivirus prevention with a firewall can be good enough for basic computing. However, TechRadar bemoans the lack of comprehensive protection, noting that the program is missing “web and email monitoring, network file scanning, and real-time cloud protection to keep you safe from the very latest threats…. These aren’t restrictions we’ve often seen in other free antivirus apps.”

Features: Unfortunately, this free cybersecurity solution is missing many features users would expect to see: web-based security, protection against malicious websites, and personal data protection are nowhere to be found.

Need a second opinion?Tech Advisor says ZoneAlarm Free Antivirus+ is “a basic, but capable internet security suite with average antivirus capabilities but a good firewall.”

Qihoo 360 Total Security 8.6

Qihoo is a Chinese company known for its antivirus software, web browser, and mobile app store.

Essential protection: Qihoo uses the same core antivirus as Bitdefender and Avira, but it lags behind them in performance. PCMag reported mixed scores on anti-malware and malicious URL blocking tests, and rated Qihoo’s anti-phishing performance as “dismal,” calling it a “phishing phail.” The AV-Test Institute gave Qihoo 360 4/6 on performance, demonstrating that it can worsen the overall system performance while it’s running.

Features: Qihoo comes with an impressive suite of bonus features, including cleanup and tuneup utilities, a vulnerability scan, and more.

Need a second opinion? TechRadar says, “There are one or two useful tools here, but 360 Total Security isn't accurate enough to be your sole antivirus app.”

Hindsight is 2020: Protect yourself now

Don’t wait until it’s too late to secure your PC against viruses and malware. As we roll into the new Roaring ‘20s, it’s more important than ever to guard against cybercrime and new threats. Get real-time security updates and 24/7 protection against viruses and other threats with AVG AntiVirus FREE. And stay safe while browsing, emailing, and downloading files with an extra layer of defense against malware.

There’s a constant debate of whether or not Macs can get viruses. If you’re still wondering: “Do I need antivirus for my Mac?” The answer is yes.

Although Macs are less likely to become a victim of a virus, it’s important to stay on the safe side. You don’t have to go overboard with the antivirus tool that you choose. In fact, you have many free options that you should consider. Here are some of the best free antivirus for Mac—don’t worry, they don’t come with any gimmicks!

1. Malwarebytes

Malwarebytes promises to scan a typical Mac in just under 30 seconds. If it finds anything suspicious, it’ll provide you with a list of potential threats. You can either choose to have Malwarebytes ignore it, or place the files into quarantine and delete them.

The Free version of Malwarebytes can help you detect malware threats quickly, but it doesn’t offer enough protection to use on its own. You’ll also get a 14-day trial of Malwarebytes Premium, so you’ll have to pay if you want access to all of its features in the future. By itself, the Free plan is just a bare-bones antivirus software—it simply identifies and erases any malicious threats.

2. Avast Security

Avast’s free antivirus for Mac is considered one of the best options for Mac users. It comes loaded with features that constantly work to block any ransomware, viruses, or malware that compromise your Mac’s security.

When browsing the web, Avast Security will let you know when you come across a potentially dangerous site, and will also keep out any web trackers. Avast even prevents malicious emails and lets you know if there are any security holes in your Wi-Fi connection.

BBB Business Profiles are subject to change at any time. If you choose to do business with this business, please let the business know that you contacted BBB for a BBB Business Profile. Note #5: These drivers have been tested to work up to Windows 10; Windows (32-bit) 32-bit installer: Mac OS X: Network Serial: Install both sets of drivers. Linux: mkudevrule.sh: Driver installation isn't required, but you might find a few udev rules helpful. Installing Drivers (Mac) For the BBB to be able to do ad hoc networking with your computer, there is nothing to install on the BBB itself. Its all set up and ready to go. However, to be able to run this on a Mac, you will need to install some drivers. Once you've downloaded the img.xz file, in my case it is titled BBB-eMMC-flasher-2013.05.08.img.xz, you'll need to extract the archive. I've found the easiest utility to use is called 'The Unarchiver'. Blackberry Extractor for Mac extracts data from.BBB or.IPD (blackberry backups) to your computer. Beaglebone black mac ssh.

Since Avast Security is completely free on its own, it withholds some extra features for the paid Premium plan. Just be careful when you install the Free plan. Avast will try to throw in some costly extra features during installation that you probably don’t want.

3. Bitdefender Virus Scanner

Bitdefender doesn’t come with many bells and whistles, but it’s still a viable option as a free antivirus software for Mac. This antivirus is especially great for scanning specific files or apps. It also allows you to omit files, making for a speedy scanning process. If it does happen to find a threat, Bitdefender will quarantine or remove it.

Bitdefender doesn’t run by itself, so you’ll need to manually prompt Bitdefender to perform scans. Fortunately, virus signatures are automatically updated every hour to ensure that you have the latest protection.

The only downside to Bitdefender is that it lacks the tools to protect your Mac online.

4. Avira Free Antivirus for Mac

This way, you don’t accidentally pass on any malware to any PC-using friends.

Despite the fact that Avira is free, it still has tons of useful features. The real-time scanner is capable of scanning your entire computer or just specific files. If you want a more hands-off approach, you can even schedule the scanner to run at certain times.

The full system scan can take a long time and tends to slow down your computer. You’ll have to perform less-involved quick scans if you want to keep your Mac’s performance up.

5. Sophos Home Free

By default, Sophos’ Home Free plan comes with a 30-day trial of Sophos’ Home Premium. You don’t have to buy the Premium version once the trial ends, but you’ll lose a couple of Premium features you might’ve gotten used to. Either way, you can still get by with just the Free plan.

Sophos Home constantly keeps tabs on the status of your Mac. It searches and detects any ransomware, malware, viruses, Trojans, worms, bots, and more that can harm your computer.

Sophos Home also comes outfitted with parental controls that allow you to prevent your children from accessing certain websites. You can have up to three devices (both Mac or Windows) on the Free plan, ensuring that everyone in your family has protection.

6. AVG

AVG’s free protection is powerful enough to secure your Mac from malware, and protect you when you’re online. It can also prevent you from acquiring and passing on any PC or Android viruses. AVG automatically updates its virus database, so you’ll always have the most effective security.

That said, you won’t need to open AVG on a daily basis. It runs in the background, and covertly deflects any threats, such as malicious emails, websites, and downloads.

If you’re looking for any parental controls or webcam blockers, the free version of AVG won’t have it. It just offers scanning and detection features, which is just good enough for basic security needs. Unfortunately, the full system scan does cause your computer to perform slowly, and you can expect it to take several minutes (or hours) to complete.

7. Comodo Antivirus

Komodo offers an easy-to-use interface and free protection for your Mac. Checking a file or app for viruses is as simple as dragging and dropping it into Comodo. It comes with a quick scan that finishes in minutes, and a total system scan that might take an hour or two to complete. The scheduler lets you pick and choose the times you want to perform scans so your computer won’t get bogged down at the wrong time.

Like some of the other antiviruses on this list, Comodo also stays up-to-date on the latest virus signatures to protect you from all types of viruses 7 Types of Computer Viruses to Watch Out For and What They DoMany types of computer viruses can steal or destroy your data. Here are some of the most common viruses and what they do. Read More . Just remember that Comodo doesn’t automatically protect you online. You’ll have to download the free browser extension Comodo Online Security if you want to block any dangerous websites.

Finding the Best Free Antivirus for Mac

Many Mac users think that their device is resistant to viruses, however, that’s just not the case. Even if your Mac is less likely to contract a virus, especially if you download your Mac apps from safe websites and steer clear of these bad security choices, it’s still possible for you to pass along malware to Windows and Android users. It doesn’t hurt to install a free antivirus for your Mac to prevent any security breaches.
