2. Avast Free Mac Security is a noteworthy antivirus for Mac, despite it lacks some functionalities.Avast Mac Security assures excellent malware detection scores in a simple interface, coming second only to the competitor Avira.

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.

When it comes to free antivirus for Windows computer, your friends will mostly recommend you either Avast Free Antivirus 2018, AVG AntiVirus FREE 2018, or Avira Free Antivirus 2018. But which one of them is the best?

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.

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?

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.
