Kaspersky vs Avast

Kaspersky vs Avast - Which one is Better?

Written by Yasir Saeed - Cybersecurity Expert

Updated on Semptember 14, 2021

In this detailed Kaspersky Vs Avast comparison, we will be pitting two of the top contenders in the antivirus market against each other. 

Avast was caught selling user data in the past, and some cybersecurity experts are skeptical about the links between the Russian government and Kaspersky.

Avast has since then shut down its data-collection company, whereas Kasperksy launched a Global Transparency Initiative. Avast actually followed illegal practices of data collection, with substantial evidence, whereas no evidence was found against Kaspersky.

We stacked Kaspersky Total Security against Avast Premium. Without further ado, let's proceed with the review.

Quick Look at the Winners in All Categories

1- Features: With Better features such as cloud backup, parental control and excellent VPN, Kaspersky came out as the winner.

2- Malware Protection: During a real-time AV test evaluation, Kaspersky scored 6/6 in performance score, making it the winner of our protection.

3- System Performance: Avast rules the roost owing to its feather-light impact on the engines (processor) of the system.

4- Pricing: Kaspersky has a better and more economical plan than Avast.

5- User Interface and Experience: Both have great user interfaces, but Avast comes out as the winner based on our tests, due to the color contrast and easy-to-understand placement of features.

6- Customer Support: If you are looking for 24/7 customer service, Kaspersky is a better option. Avast usually has premium technical support that is paid to resolve any issues.

Key Features Compared

Cloud Backup

Cloud Backup is an important feature that keeps the data secure, lessens downtime, and provides you access to vital information anytime, anywhere. The copies are stored in the clouds to keep the customer on cloud nine.

Amazingly, Kaspersky envelops this feature and gives an extra boost to the security of your data.

Kaspersky Total Security


Customers use the VPN (Virtual Private Network) to increase data privacy whilst browsing. Kaspersky provides a bundled VPN with a 300 MB daily bandwidth limit in their 30-day trial version, whereas Avast provides a 7-day free trial of its Secureline VPN services with no data limitations.

Safe Banking

If you are making transactions online, chances are someone might be prying on your activities. With this feature enabled, your connection and data transfer to and from the banking website is encrypted.

Kaspersky and Avast in their premium suites have this feature. Personal financial information such as credit cards and bank account username/passwords will not get compromised.

Kaspersky Safe Money

Kasperksy’s Safe Money option allows you to add safe websites and encrypt your transactions.

Avast also has a safe banking mode, but you need both Avast Antivirus and Avast Secure Browser to enable Safe Bank mode. Kaspersky takes a lead in safe banking because this feature already comes in their Total Security version.

File Shredder

File shredder allows users to permanently delete all data. The process intelligently occupies the deleted file space by deploying the ones and zeros instead of original data. Although less in number, this feature is a key requirement of the important segment.

Avast File Shredder

Avast does not provide any algorithm, making it simple for a non-techy to permanently delete all data.

Both programs provide data shredding options. However, Kaspersky didn’t provide this feature in its Internet Security package, but it is included in Total Security.

Kaspersky File Shredder

Kaspersky’s Data Shredder provides you with several different algorithms to choose from when shredding files.

Password Manager

Avast does not have a dedicated password manager to store all your passwords. However, it does have a feature that constantly scans all saved passwords across different browsers to ensure no malicious app has access to it.

Malware Protection Capabilities

We ran some tests to see who will take the win in the malware protection category. This includes data from independent sources such as AV-Test, as well as our findings. Our findings indicate Kaspersky as the best in malware protection.

EICAR-based Testing:

The very first test was about the malware dangers in real-time.. Furthermore, we got the sample malware-infesting files from EICAR (The European Institute for Computer Antivirus Research). The following comparison table shows the EICAR results:

Anti VirusEICAR Sample AEICAR Sample BEICAR Sample CEICAR Sample DLive Sample  (Adware)Live Sample  (Trojan)


Kaspersky single-handedly identified and neutralized all EICAR samples by blocking them forthwith. It immediately deleted the malware right after zipping or unlocking. On the flip side, Avast was unsuspected on HTTPS mode, and the malware penetrated the system. Avast blocked all three in HTTP and live mode. 

Sneaking into Database

To corroborate the existing data points, we took the latest available record from two trending websites in this genre; AV-Comparatives and AV-Test. Both websites have anti-virus testing labs.


For the May/June – 2021 results, AV-Test analyzed 21,262 samples for Avast; the industry average of protection is 98.9%, following the 100% result of thwarting the widespread malware. For June’s protection against 0-day vulnerabilities, Avast scored 99.3%, better than the industry average.

AV-Comparatives False Positives

We also looked into the archives of AV-Comparatives. AV-Comparatives runs false alarm tests that counter-checks how precisely an app or file is declared as a threat.  The results show that Avast succumbed to 20 false alarms as compared to 0 for Kaspersky.

The test results were from February till May 2021.

These independent tests declare that Kaspersky fares better than the Avast if we go by the archives of independent labs.

System Performance

Performance is the key. Efficient software cannot make a good impact and is of zero value if it slows down the system's performance. Hence, both Kaspersky and Avast are individually tested on the merits of system performance.

The results are as follows:

Performance on PC

A viable antivirus not only saves the computer from cyber threats, but it uses the minimum resources to prevent the system from coming to a halt. According to the AV-Test evaluation, Kaspersky and Avast both scored a perfect 6.0 in system performance. However, Kaspersky scored 100% in June 2021 results where Avast lagged behind at just 99.3%.

Performance on Mac

The macOS antivirus utility does a good job as the system’s default scanner, to provide a decent level of protection against spyware, malware, and antiviruses. However, there are many strains of viruses that Mac OS may not be able to detect and thwart.

This is where professional antiviruses come in. Similar to exceptional performance on PC, Kaspersky and Avast both provide excellent level of protection in advanced threat detection and removals, with high rates of success.

Before moving on with the performance, both antivirus vendors provide the same set of features for Windows and Mac OS, such as VPN, File Shredding, Sandbox (Avast only) etc. The comparison is more in terms of scanning, detecting and thwarting real-time threats.

According to test results conducted by AV-Comparatives, Avast and Kaspersky both secured 100% in malware detection and blocking rates as illustrated in the following graph of 2021:

However, in detecting PUAs (Potentially Unwanted Applications) on the Mac OS, Avast scored 99% whereas Kaspersky scored 96%.

System Utilization

When it comes to performance, how much RAM and CPU are consumed during scanning is also an important metric to decide which antivirus performs the best.

Based on our own independent tests, Kaspersky consumed only 88.5 MB RAM whilst running a quick scan as well as 12.2% of CPU power.

In our independent tests of memory and CPU utilization, Avast consumed 114.1 MB, higher than Kaspersky’s 88.5 MB, but the CPU utilization rate was nearly half at 6.8%

Avast consumed more memory but 50% less RAM as compared to Kaspersky. Honestly, we didn’t experience any system lags when a quick scan was running for both programs. However, we believe that Avast excelled here as it was more lightweight than Kaspersky.

AV Ranking

Source: AV-Comparatives

Both Avast and Kaspersky scored an Advanced+ 3 star rating with the likes of AVG, Avira, Bitdefender, and McAfee. This shows that these products have the lowest false alarms i.e. false positive detection rate.


Macs are usually known for improved efficiency and faster speeds as compared to their Windows counterparts. Quick scan times using both software took roughly between 2 to 4 minutes, which is usually the same across all the antiviruses tested on Windows OS.

However, it is deep scanning where Mac OS shines. A deep scan varies from system to system and may take anywhere between 30 minutes to 90 minutes on Windows OS. On the Mac OS, it takes around 15 to 30 minutes for a deep scan.

Both programs provided the option of a custom scan by selecting the drives and folders to scan.

Avast Scanning

Avast Antivirus - Quick Scan Results. Time to scan approximately 2 minutes.

But it is a deep scan where both competitors shine out with their true malware and virus detection capabilities.

Kaspersky took 37 minutes to scan our system with a single 120 GB SSD only, and here are the results. It detected 3 infections with a total of 11 events.

Kaspersky Scanning

We did a deep scan on another system with a 256 GB SSD and a 1 TB HDD all full to the brim and it took us around 1 hour and 15 minutes to complete the scan during which Avast detected 51 malware threats:

Kaspersky Free vs Avast Free

Kaspersky Security Cloud offers full-scale protection without any charges. However, the free version does not offer tech support and has limited features for iOS. It is only free for private but not commercial use. The Free Kaspersky version automatically updates database signatures in the background. 

Avast Free

On the flip side, Avast's free version garners excellent scores from the independent labs. But all the lunches are not free, the boot-time is a bit slower. Avast offers excellent protection for its free version.

Kaspersky Free

Free versions of both antiviruses only offer protection against viruses and do not have advanced security options such as a password manager, privacy control, parental control, and protection for multiple devices.

If you’re just starting, remember that the free versions should provide an adequate level of protection. If you are looking for advanced security options, such as protection for multiple devices or parental control, it is always a wise idea to upgrade to the paid versions.

Kaspersky vs Avast for system performance: Avast

As the table is self-explanatory, both Kaspersky and Avast offer their versions of free protection. The basic versions entice the customers to sign up and purchase advanced versions for ultimate protection. The pricing hierarchy is simple. One important point to know is that Avast provides collective protection for up to ten devices while Kaspersky protects up to five.

Both Avast and Kaspersky offer a 30-day money-back guarantee along with discounts on first-year purchases.

Avast has a clear pricing plan with protection for up to 10 devices (including ios, mac, pc and android). However Kaspersky has pricing plans with different devices as well as PC protection. This is a bit complicated to understand.

Ease Of Use and User Friendliness

Being simple and having an intuitive user interface is the forte of an excellent antivirus. Let's first look at Kaspersky's interface.

The open-frame interface is laden with light colors, while the parental controls and scan options are prominently displayed. All the options are accessible with a few clicks. The green checkmark shows that your computer is safe. In the case of an anomaly, it turns red.

More Tools Option

This is the main dashboard when Kaskersky starts. To access more options, click on More Tools.

Here, you will see further options neatly categorized for each tab. There are even PC Cleaning and Optimization tools.

Let's compare the Avast interface.

Dark background and white font colors stand out, alongside the Orange logo color and the green button colors. The large and well-organized buttons can be leveraged by a person having basic computer skills. The left side rail houses all the operations into the extensive menu.

Most user-friendly provider: Avast  

Customer Support

Avast customer support extends assistance through chats and emails via paid phone calls for remote assistance. The listed FAQ does not require a user to contact the chat.

Kaspersky support is available between 7 am to 1 am, seven days a week. The customers get quick responses by email or phone calls. Moreover, the FAQs, videos, and other resources are also extremely helpful.

Kaspersky Customer Support

Kaspersky does not charge extra for support calls, which is something that Avast is doing even with the paid versions of their products. We did not find this a lucrative offer. Pricing starts from $79 per call to get help from an Avast technician and use remote assistance for problem-solving.

Fixing Pricing Plans

Best customer support: Kaspersky


After a thorough review and tests, Kaspersky comes out to be the ultimate winner with strong protection rates for malware (EICAR) tests, and better performance than its competitor, Avast. You also need not worry about using a Russian product for cybersecurity needs as all claims against Kaspersky are baseless.
