AVG provides internet protection, performance and privacy solutions for individual customers and businesses for Windows, macOS and Android operating systems.

Features comparison

As we mentioned before Avast offers a wide range of features in all of its plans.

  • Avast Free Antivirus offers a decent set of security and privacy features, including a secure web browser, a password manager, home network scanner, or a hardened browser. Many of these features usually come only in paid antivirus programs, while Avast offers them for free.
  • Avast Internet Security also includes premium features such as protection while banking and shopping online, Sandbox suspicious apps, a strong firewall against hackers, protection against spam and phishing emails and an extra layer of ransomware security.
  • If you need more, Avast Premier protects against webcam spying, allows users to permanently delete sensitive files and information, and automatically updates applications on the PC.
  • Avast Ultimate offers all above and also includes Avast SecureLine VPN, Avast CleanUp Premium and Avast Passwords Premium.

Just like AVAST, AVG offers similar security products for Windows users.

  • AVG AntiVirus Free is essential to free protection that includes antivirus, anti-spyware, anti-ransomware and anti-malware features. It also blocks unsafe links, scans your PC for performance problems and includes real-time security updates.
  • AVG Internet Security includes all the mentioned and additional features such as an extra anti-ransomware layer, Webcam protection, Enhanced Firewall, secures financial information and payments. It also includes AVG Antivirus for Android.
  • AVG Ultimate is an all-in-one package for all devices, that includes all the Internet Security features, advanced Antivirus & TuneUp, Live phone and chat support, real-time security and tuning updates, includes Mac & Android apps.

Both security providers include similar features and offerings, however, Avast includes more free features, such as password manager, a game mode and a hardened browser.

Antivirus protection comparison

Avast and AVG apply same antivirus defenses that include a traditional signature-based scanning and activity and code snippets. By combining these two security layers antivirus defenses are able to detect both, zero-day and widespread malware samples.

If the antivirus detects anything suspicious, all the suspicious icons are sent to the companies’ cloud-based servers for further examinations.

We have installed both programs in our test PC running Windows 10. Both providers received the same results, as they both share the same malware-detection engine.

AVG demonstrated the same malware detection results like Avast.

According to the independent testing lab AV-TEST, Avast detected 99.3% and 99,4% of zero-day malware attacks, including web and e-mail threats. It also detected 100% of widespread and prevalent malware.[5]

Detection of most common spread malware in last 4 years 100% 100%

There is no surprise that Avast and AVG demonstrated the same results as they share the antivirus engine.

System-performance impact and scans comparison

Avast Antivirus does not drain the computer system and does not use many system’s resources. In addition, the antivirus does not have a noticeable impact during scans.

AV-TEST also tested the performance of antivirus products.

AVAST Impact on the system:

  • Impact on the system when launching popular websites – 10% (13%).
  • Impact on the system when downloading frequently-used applications – 2% (1%).
  • Impact on the system while launching standard software applications – 17% (12%).
  • Impact on the system while installing frequently-used applications – 26% (25%).
  • Impact on the system while copying files – 2% (3%).

AVG Impact on the system:

  • Impact on the system when launching popular websites – 18% (13%).
  • Impact on the system when downloading frequently-used applications – 1% (1%).
  • Impact on the system while launching standard software applications – 16% (12%).
  • Impact on the system while installing frequently-used applications – 28% (25%).
  • Impact on the system while copying files – 2% (3%).

As you can see the results are similar. When it comes to scanning results, a full initial Avast scan took about 1 hour and 30 minutes. While AVG took only about an hour and had not much of an impact on system performance.

  avast avg logo
Slowing-down when launching popular websites 25% 18%
Slower download of frequently-used applications 0% 1%
Slower launch of standard software applications 13% 16%
Slower installation of frequently-used applications 18% 28%
Slower copying of files (locally and in a network) 2% 2%
Overall rating 9.2 9.4

So even though the performance results are similar, AVG offers quicker scans that take less of the system resources.

Customer support comparison

Avast and AVG both provide customer support for free neither via phone or email.

However, with Ultimate subscription, you will get 24//7 free customer support. In addition, both providers offer tech support with a knowledge base, online forums, FAQs, installation tips and more product-related information.

User interface comparison

Avast user interface cannot be resized or viewed full screen but can be moved around. The interface is light, simple and easy to navigate, as all the major features are provided in the left-side menu bar.

AVG has a dark-skinned interface. The available features are provided in the main window. In addition, it offers more settings and options on the upper side of the screen. However, these settings do not include back arrow to simply return to the previous screen.

We found Avast interface more pleasant and easier to use.

Antivirus software market share comparison

According to OPSWAT’s streamlined Windows Anti-malware Market Share Report, which includes the most recent data collected for 6 months from June to December, Avast and Avg (both) software has the largest market share among the most popular anti-malware products with 18.44% of the total antivirus market share.

Manufacturer/Brand Market share
avast 18.44%

bitdefender 10.54%
eset 9.09%
webroot 7.03%
spybot 6.29%


So we have to admit that Avast Software has the largest market share in the security industry. It is worth mentioning that its market share also includes AVG users.

As you can see in the graph above, other popular products include McAfee Inc., Malwarebytes, ESET, Webroot, Kaspersky Lab, Safer Networking Ltd with SpyBot Search & Destroy, Avira, and Symantec with Norton.

So we have to admit that Avast Software has the largest market share in the security industry. It is worth mentioning that its market share also includes AVG users.

The final verdict

When it comes to Avast, the application demonstrates decent but not superior malware detection rates and light but still a notable impact on the system. It also includes a variety of additional features.

AVG is a member of Avast family and is also one of the best players out there. However, it offers a limited feature set.

All in one, we found that Avast is more customizable and pleasant to use, in addition, it’s offerings are wider.

Avast and AVG are ones of the best antivirus systems out there. Together they take the largest market share of anti-malware industry products, according to the Windows Anti-malware Market Share Report by OPSWAT.

Both of the antivirus programs are worth their price.
