If most antivirus software interfaces evoke existential dread, Panda Free Antivirus is an outlier. Their apps use nature scenes with a trendy user interface, which is one of several. However, despite its unconventional taste for color palettes, background images, and thus the odd choice of name, it’s one of the most capable free antivirus options you’ll find.

Of course, once I say capable, I only have Windows and Android in mind. Mac and iOS users will have to look elsewhere because the only versions that are available to them are the paid ones.

However, the list of features for Windows can be much longer than you would normally find. There is real-time malware protection, it will schedule periodic system scans and crashes against automatic malware execution from USB devices.

Malwarebytes – Best Free Lightweight Antivirus

The free version of Malwarebytes is nothing of the sort.

Real-time protection:Paid
Platforms:Windows, macOS
Customer support:24/7 email

If you simply need an antivirus to clean your PC from time to time, Malwarebytes is an exceptional tool. However, Malwarebytes is often used as an additional antivirus by users, as it can remove threats that are not detected by other scanners. for example, the program examines your system’s boot records using a rootkit scanner, so it operates even within the deepest layers of your system.

Malwarebytes Free can be a lightweight solution by design that consumes few system resources and sacrifices additional features in favor of efficiency. So, suppose you have an older or weaker machine. in that case, you should be aware that you will get much less initial hit with Malwarebytes compared to other options on the market.

The main problem is that it does not have any web protection function. Block dangerous URLs online, but this does not apply to email attachments. Therefore, malicious files that you simply get through other sources will meet no resistance and can be found on your system. This is usually a priority, so you should use some real-time protection measures, such as the default Windows security.


You are ready to install Malwarebytes on Windows, macOS, ChromeOS, Android, and iOS devices. As is often the case, the iOS version can be the laughing stock because it provides protection only against malicious URLs.

If you’re using the free version and then decide you just need one more touch, you’ll get a 14-day free trial for Malwarebytes Premium. Add features like ransomware protection, anti-phishing measures, and an anti-crypto-jacking response.


  • One of the lightest options
  • Works well with weaker devices
  • Detects hidden malware in deep layers
  • Good Malware Labs Results

How we selected and tested

Sorting out the simplest antivirus programs is a tedious task. We tested several antivirus services before selecting those that deserve a place on our list, paying the utmost attention to their ease of use, intuitiveness, and virus detection rates.

We also collect data from reputable anti-malware labs such as AV-TEST and AV-Comparatives. Then we draw conclusions for the simplest relationship between security, performance, and other additional benefits such as customer support and additional features.

Is it safe to use a Free Antivirus?

A free antivirus solution is minimal, but it’s better than no protection. Sometimes it will be comparable or better than the built-in antivirus applications. For this reason, it is essential to be picky and learn what you really get: if you install an antivirus, you will likely disable other built-in options.

However, you should be aware that free antivirus tools sometimes don’t have an important feature called real-time protection. This suggests that a free app will only remove the predominant threats, it will not prevent new malware from entering your system.

Free Antivirus vs Paid Antivirus

When it comes to free and paid antivirus programs, the last option is usually the highest. For example, once you get a paid antivirus tool, it will make sure that it protects your computer from online threats while browsing online. Also, the paid apps will always offer customer support like live chats, while their free versions will only allow you to use their knowledge bases.

Plus, paid antivirus tools (like our best antivirus in 2021 list) include tons of useful features that will enhance your online experience. Built-in VPNs, parental mode, and various browser extensions are often helpful for beginners and advanced users alike.

However, when chosen carefully, even a free antivirus program is usually sufficient. Take the free version of Bitdefender as an example. It uses equivalent advanced technologies because the paid version protects you from malware. the only thing that the free option lacks is some additional features.

So if you simply need basic protection against malware, free antivirus software is usually sufficient, but only chosen wisely.

Is it Worth it to Pay for Antivirus?

If you want the simplest experience possible, you add up to buy the subscription. Generally, you will get more online protection features and you won’t need to see all the grayed-out icons asking you to subscribe when pressed. Plus, it always means better customer support in case something goes wrong.


How can I get free antivirus? 

Usually getting a free antivirus is as simple as accessing the provider’s website and downloading an app. In other cases, you might have to go to the dedicated app store like Google Play or Microsoft Store to download the app. Most free antivirus services do not require registration, so you should be ready to use them right from the start. It usually makes more sense to sign up because that way you will get a free trial of the premium version.

Is it safe to use a free antivirus? 

If you stick with reputable antivirus service providers, there is nothing wrong with using the free version. Usually, it will be a bit limited compared to the paid version, but you will feel safe using it.

Will my computer become slow if I install an antivirus? 

If you have an older device, it will be more difficult for you to meet some demands of the antivirus service. Very frequent background scans can make your system feel sluggish, especially once they are performed when you are performing other tasks. However, lately, computers have a lot more resources than before, so the performance impact should be minimal.

What is the best free antivirus in 2021?

Today, the simplest free antivirus is Bitdefender. It uses machine learning to detect suspicious software behavior, offers customer support even for non-paying users, and protects you from network threats and phishing.c
