Sophos has less of an impact on the system than Avast, possibly because Avast has more features or maybe because Sophos is written better, I don’t know. In the latest test Sophos impacted system performance by 8.86 – 12.53% on various Intel Macs and 18.25% on a PowerPC G5 when performing a full system scan. Avast may free up money for other things, but in a setting like a school where you have lots of kids and teachers bringing in things from home, Sophos is going to protect you from things that Avast won't.

When it comes to free antivirus for Windows computer, your friends will mostly recommend you either Avast Free Antivirus 2019, AVG AntiVirus FREE 2019, or Avira Free Antivirus 2019. But which one of them is the best? All are completely for free and offers plenty of advanced features. We’ll take a look at details on Avast and AVG.

Two biggest competitors, Avast and AVG, are today a single company. In October 2016 Avast acquired AVG company for $1.3B. From the end-user point of view, there is no change, both brands continue to coexist together. However, they use the same engine and technology in the background – the one from Avast. Feature-wise there are small differences, let’s take a closer look.

Feature Comparison Table – Does AVG Offer More Than Avast?

Both Avast and AVG are offering solid protection against viruses, spyware, malware, rootkits and even ransomware which is a big topic now. Plus you will be secured while browsing online, chatting on Facebook, or watching videos on YouTube. Also, they will protect and scan your incoming and outgoing e-mails if you are using an e-mail client like Outlook or Thunderbird. If you’re a gamer, you can relax – both antivirus solutions offer smart gaming mode and keep themselves silent.

With Avast you will get some cool features like Wi-Fi Inspector (formerly called Home Network Security), which scans your home network, Wi-Fi connection, and routers. An easy-to-use tool called Browser Cleanup for removing unwanted toolbars from your browser. Software Updater for monitoring the up-to-date status of the other software like browser, Java, Adobe Reader, etc. And you can ask your IT friend to fix your computer via the secured remote connection.

However, there are some differences. AVG offers spying and data theft protection controlling what kind of data you are sharing with the other applications, and File Shredder which can permanently delete your sensitive information, so they can’t be restored. A similar feature called Data Shredder is available also in Avast, but only in the top-tier product Avast Premier, not in the free one.

A big plus for AVG is that you don’t need to register or give out any personal information. You can just download, install, and keep using it. With Avast you have to activate the product within the first 30 days, and then once a year.

Impact on the System Resources – Which Product is Lighter?

We have measured the impact on the system resources using two ways:

1. How long does the computer to boot into Windows desktop while the AVG or Avast is installed
2. How does the computer perform in various areas (CPU, Graphics, Memory and Disk operations) while the AVG or Avast is installed

In the boot time test where less is better, it took only 28 seconds (on average) to load Windows desktop when Avast Free Antivirus was installed. The same operation took 33 seconds (on average) when AVG AntiVirus FREE was installed. Default boot-time without any antivirus solution in place took 20 seconds. So according to our testing, Windows loads faster with Avast.

In the second area, we have tested computer performance in various areas and impact of the AVG or Avast on the results. Test results (higher is better) were practically the same for both products, 2,116 points for Avast and 2,115 points for AVG. The default performance without any antivirus installed was 2,150 points. So the overall impact on the system performance is really low for both products.

Final performance test results are highlighted in the chart below. You can clearly see the difference between no antivirus and Avast or AVG present. Please note the vertical axis ‘Performance Score‘ is not starting from 0, but from 2,110 to clearly show the small differences.

Avast vs. AVG – Performance Test Results

You can find more details about how we tested in the ‘Additional Notes‘ section at the end of the article.

User Interface – Is Avast Easier to use Than AVG?

Avast user interface is really nice and clear. There is only one main action leading to the Smart Scan, which runs all seven Avast scans: compatibility, viruses, outdated software, browser add-ons, router issues, performance, and weak passwords. The green button ‘UPGRADE‘ (or ‘ACTIVATE‘) leads to a comparison table of Avast Free Antivirus and Avast premium product (Avast Internet Security).

The status is also indicated by color when green obviously means ‘You are protected’ (note AVG is using the exact same term). Also, you are assured that ‘Everything is up-to-date‘. The top menu is easy to navigate and structured in fours groups – Scan, Tools, Passwords, and Store. What is pretty annoying is the top menu disappears every time you go from the home screen and you need to click on ‘Menu‘ to get it back.

Same as AVG, also Avast is using the bottom space for the up-sell offers.

AVG user interface is quite busy compared to Avast. When everything is fine, you will see green tick marks with the message ‘You are protected‘. The interface will go red if there will be some issue. What is nice is when some of the shields are disabled, you will see immediately which ones as they will also turn in red.

AVG AntiVirus FREE 2019 – User Interface

The main tiles show you the status of the specific shield protection. If you are looking for a scan, it’s the less visible button ‘Scan now‘. The ‘Fix performance’ button sounds pretty interesting, but you need to download other product (AVG PC TuneUp) to actually fix the performance. The last button is for checking if the program is up-to-date, of course, the virus definitions are updated automatically. ‘Join us on Facebook‘ link at the top bar is very visible and somehow distracting.

Bottom of the interface is used as an offer space to buy or try for free the paid-for version.

Localizations/Translations – Is The Product Available in my Language?

Both Avast and AVG are available in plenty of languages, of course for free. But Avast offers many more.

Avast languages (46): Arabic, Belorussian, Bengali, Bulgarian, Catalan, Chinese (simplified), Chinese (traditional), Croatian, Czech, Danish, Dutch, English (United States/United Kingdom), Estonian, Finnish, French, German, Greek, Hebrew, Hindi, Hungarian, Indonesian, Italian, Japanese, Korean, Latvian, Lithuanian, Malay, Norwegian, Persian, Pirate talk, Polish, Portuguese (Brazil/Portugal), Romanian, Russian, Serbian, Slovak, Slovenian, Spanish, Swedish, Thai, Turkish, Ukrainian, Urdu and Vietnamese

AVG languages (22): Chinese (simplified), Chinese (traditional), Czech, Danish, Dutch, English, French, German, Hungarian, Indonesian, Italian, Japanese, Korean, Malay, Polish, Portuguese (Brazil), Portuguese (Portugal), Russian, Serbian, Slovak, Spanish, Turkish.

Popularity – Which is the Most Popular Free Antivirus? Avast or AVG?

The better product is, the most users it has. It’s simple as that. However, it’s not easy to say which is the most popular antivirus, if Avast or AVG. For expressing popularity we are using several, publicly accessible methods.

1. Official Sources

According to the official website, Avast is protecting more than 400 million users worldwide, but that probably includes also AVG users. The last publicly available number was 230 million users. AVG doesn’t state anymore how many users are using their products, however using simple math it’s around 170 million (400 – 230 = 170). Therefore we believe it’s safe to claim Avast has more users than AVG.

2. Antivirus Vendor Market Share by OPSWAT

OPSWAT is regularly releasing reports about the antivirus market share. Data are based on the OPSWAT GEARS software installed on the client machines. According to the latest report from November 2017, Avast is dominating the worldwide market with 18.48%. Followed by ESET with 13.97%. AVG is still reported as a separate company and didn’t make it into top 10 for June 2017, however, AVG’s share was around 4% in the last few months. It is also important to mention Microsoft for some reason is not included at all.

3. CNET Download.com Ranking

Download.com by CNET is the World’s most popular download portal. According to its popularity rankings, AVG has more total downloads – almost 564 million, while Avast has ‘only’ 406 million. However, the recent trend shows Avast is slightly more popular, as it leads the last week downloads number.

Avast vs. AVG – Number of Downloads & Rating on CNET Download.com June 2017

Avast has higher editor’s rating– 4 stars (meaning excellent), while AVG has 3.5 stars (meaning very good). The user/community rating is also better for Avast – 4.5 stars, while AVG has 4 stars.

4. Number of Fans on Social Media Networks

Another way how to measure product/company popularity is the number of fans/followers on social media networks like Facebook and Twitter. Avast is leading on Facebook with 4.1 million fans vs. AVG’s 3.1 million. On Twitter, the leader is AVG with 216k followers vs. Avast’s 181k.

Independent Labs Test Results – Will AVG Protect You Better Than Avast?

Sophos For Mac Download

If you are looking for a more advanced comparison of antivirus protection, the best resources are the independent test labs. These labs are regularly performing various tests like how many viruses will get through the antivirus software, or which vendor offers better performance.

Selection of the most important and relevant test results is below:

• AV-Comparatives Real Word Protection Test Results (November 2017)
• AV-Comparatives Performance Test Results (October 2017)
• AV-TEST Avast Results (October 2017)
• AV-TEST AVG Results (October 2017)

As we mentioned the antivirus engine is the same for both products and that’s also visible in tests. In the latest AV-Comparatives Real-World Protection Test from May 2017, both Avast and AVG got 100% detection rate with 0 false-positives. Both products also scored the same score on the latest Performance Test.

Respected computer magazine PCMag gives both products the same rating of 4,5 stars in their comprehensive comparison of free antivirus solutions written by security expert Neil J. Rubenking. Actually, both Avast and AVG are their #1 recommendation for the free antivirus software.

Our current Editors’ Choice products for free antivirus utility are Avast Free Antivirus and AVG AntiVirus Free. Both get very good scores from the independent labs, and in our own tests as well. Both include some useful bonus features.

What We Don't Like

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.

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.

• 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.

• Doesn't use up lots of memory or CPU.

Avast For Mac Free Download

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.

Avast For Mac Review

• 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 For Macbook

Sophos Home for Mac can protect every Mac in your home from malware, viruses, and ransomware. It also can protect your web browsing from stumbling across inappropriate websites that may contain phishing schemes or malware.

Sophos uses signature-based as well as heuristic-based behavioral detection to monitor the unusual behavior of apps to identify suspicious activity. Like most antivirus apps for the Mac, Sophos can detect Windows-based threats as well, helping to prevent cross-platform contamination.

• 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.

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.
