Performance in Independent Lab Tests

Avast’s cloud-based technology makes it super-efficient in identifying even the most recent types of malware and update its database in real-time. How well Avast protect your devices? Let’s have a look at some independent lab tests and find out.

Protection Tests

Needless to say but protection is the primary domain for an antivirus product and the most significant one as well. We’re going to look at test results from two independent testing organizations, AV-Test and AV-Comparatives. These stats will inform us how effective Avast antivirus is against different types of malware.

The first evaluation we are going to consider is the latest Protection Test from AV-Test. The organization assesses and rates antivirus products against zero-day and widespread malware on a scale from 1 – 6. 6 is the best score here.

Avast scored the highest rating in this assessment, receiving full 6/6 score.

Next AV-Comparatives ran its own Real-World Protection Test to measure antivirus software against the malware transmitted over the internet. Avast was a little behind on this test and received the second position with an ADVANCED award.

Real-WorldProtection TestResults AV Comparatives- July Octuber 2019

However, the organization also recently concluded its Enhanced Real-World Test 2019. This test evaluates antivirus programs for Advanced Threat Protection, including targeted attacks, exploits and fileless threats.

In this assessment, Avast was one of the very few products to get the ADVANCED+ award which indicates its robust security infrastructure against advanced cyber threats.

The company also demonstrated similar performance on AV-Comparatives’ Malware Protection Test against malware types transferred through network drives, USBs and other removable media.

Once again, Avast received the highest ADVANCED+ award in this evaluation.

Overall, Avast has given an outstanding performance in the protection tests with the proven ability to shield your devices well against all kinds of malware and digital threats.

Performance Tests

When it comes to antivirus security, performance is almost as significant as malware protection. You don’t want software that slows down your system or impedes your routine tasks. 

So, once again, let’s go back to our independent testing organizations to see how well Avast fared in the Performance evaluations.

The Performance Test by AV-Test evaluates software’s performance while running daily usage tasks, including visiting websites, installing and opening frequently used apps, copy or moving files etc.

Avast was just shy of the perfect score with 5.5/6 points in this assessment. Still, it’s an excellent performance rating.

But let’s see how Avast performed in AV-Comparatives Performance Test, which is pretty similar to AV-Test’s performance assessment.

Avast performed brilliantly here as well and secured the ADVANCED+ award once again.

Avast claims to be very light on your system, and the test results show that it lives up to that claim, having demonstrated little to no impact in the performance assessments from both testing organizations.

However, it is also worth mentioning here that Avast was reported to collect users’ browsing data and sell it to third parties through its parent company Jumpshot. Avast doesn’t deny this statement.

But the company did state that it doesn’t collect personal identification information like names, emails and other contact details. The company also said that users have the choice to opt-out of sharing their data.

Now, this may sound of concern to you. But there’s something else we need to consider here. Just because Avast got reported because of its seemingly open practice does not mean that other companies refrain themselves from doing the same. 

Maybe not if they claim so. But in other cases, companies likely follow Avast’s footprints when it comes to sharing users’ data with third parties. 

Pros and Cons


  • Top-drawer protection from a wide range of malware types
  • A wide variety of advanced security features and utilities 
  • Minimal digital footprint
  • A range of protection features targeted at securing Windows and Android devices which are far more prone to malware attacks compared to Apple devices
  • Multi-device package is quite attractive considering the value Avast offers with it


  • Single-device suite is too expensive
  • Collects and sells user data 

Final Verdict

We’ve seen from our examination of Avast’s features, protection and performance standards that it is a robust antivirus solution and one that is worth investing in. You can safely trust the company for all it claims to protect.

As far as the user data privacy issue is concerned, apparently, the company has taken responsibility and addressed the issue, prompting users to make an opt-in or opt-out choice for data sharing consciously.
