Best free antivirus software

Using an antivirus is one of the most effective methods to protect yourself against viruses. Although most new operating systems include anti-malware software, you may want to use a third-party solution. They usually have extra functions in addition to assisting you in removing dangerous software. Unfortunately, most top-tier antivirus software isn’t free.

However, if you’re on a tight budget, a free antivirus program may be all you need. As a result, we’ve prepared a list of the top free antivirus suites, regardless of the operating system you’re using.


It’s no surprise that Bitdefender is a great free antivirus program. Bitdefender offers one of the most comprehensive feature lists for a free service.

On Windows, it features Bitdefender Shield, which provides real-time protection against a wide range of cybersecurity threats. It analyzes your files and emails in real time, with minimum impact on system performance.

However, the service does not rely solely on database information. Their Advanced Threat Defense detects behavioral threat-like signals via machine learning. Imagine a piece of software is accessing too much data, changing or uploading data in the background. In such an instance, it will be identified as a new type of malware long before it enters the database.

Bitdefender also has anti-phishing measures in place. Every page you visit is rigorously scanned for phishing indicators, ensuring that your information does not wind up being sold on dark web marketplaces.

For non-paying users, Bitdefender provides excellent customer assistance. If you have any problems, you may contact their customer service representatives by live chat, phone, email or community forums. When it comes to free antivirus software, practically no other provider offers as many alternatives.

The biggest disadvantage of this service is that there is no free version for Mac. For malware cleanup, it only has a standalone Virus Scanner. The iOS version, likewise, has few functions.

The base version is free forever, however if you want to trial the premium editions, you may do so for free for 30 days.

Avira Free Security

The latest tool, the successor to the former Avira Free Security Suite, combines the capabilities that it used to offer and adds fresh ones to keep the service effective and relevant. It has the feel of a somewhat restricted, but still outstanding, version of their premium program.

Although there are many fantastic antiviruses available regardless of your device type, support is a vital feature that sets this service apart from the rest. Avira offers a fantastic lite version for PC, Mac, Android, and iOS. As a result, it covers all bases and provides equivalent performance across the board.

Avira receives the top grade score for macOS protection in independent testing, which is quite amazing. It’s common practice in the business to ignore Apple customers because they’ve typically been safer when it comes to viruses. Meanwhile, Avira has real-world test results to back up its claims of performance.

If you’re a Windows user, they’re equally as good on PC. So, no matter what system you use, you’ll receive a decent antivirus. The installation process is straightforward, and Avira will update automatically, so you won’t have to do anything to ensure your protection.

As a free user, you get ransomware, system, and web protection. The latter, on the other hand, will be offered independently through the Browser Safety add-on. Even the free version detects all known ransomware threats, so you’re receiving the entire package.

Overall, extensions such as Browser Safety and Safe Shopping help to make your surfing experience safer. They have benefits, whether you’re concerned about invasive trackers or someone stealing your data. There’s also a VPN, although with a monthly limit of 500 MB, it’s hard to call it a helpful feature.


When searching for a security service, you may feel as if your selection isn’t actually light enough. This is especially true for companies that provide the identical programs as their premium counterparts, complete with features you can’t use unless you subscribe. That is not the case with Malwarebytes Free.

Malwarebytes is an excellent program if you simply need an antivirus to clean up your PC every now and then. However, consumers typically use Malwarebytes as an extra antivirus since it may identify dangers that other scanners miss. For example, the application uses a rootkit scanner to check your system’s boot records, allowing it to operate even in the lowest layers of your system.

Unfortunately, this means that you won’t find features such as a VPN, firewall protection or a password manager. Malwarebytes Free is a lightweight solution by design, consuming minimal system resources and foregoing additional functionality in favor of efficiency. If you have an older or less powerful computer. you should take note because Malwarebytes has a significantly smaller startup effect when compared to other alternatives on the market.

The primary issue is that it lacks web protection capabilities. It does prevent harmful URLs on the internet, but not email attachments.

As a result, malicious files obtained from other sources will encounter no barriers and will end up on your machine. Because this is a problem, you should employ some real-time protection mechanisms, such as the default Windows Security.

If you’re using the free version and feel you need something more, you can grab a 14-day free trial of Malwarebytes Premium. It includes ransomware protection, anti-phishing techniques and a solution to crypto-jacking.

Kaspersky Security Cloud

When it comes to free virus removal services, Kaspersky has one of the most extensive track records. However, don’t expect Kaspersky Security Cloud to have many similarities with their flagship Kaspersky Anti-Virus. Nonetheless, while there is a persistent impression that the suite is being held back in order to preserve more features in the premium edition, the bundle you receive is valuable.

You receive the standard functions, such as system scans, but there are some extras. There is a System Watcher function that employs machine learning to detect malware that it has never seen before. There’s also the Network Attack Blocker, which will notify you if it detects suspicious connections on your LAN.

Not all risks come in the form of malicious software. In certain cases, an unpatched software component might be attacked by hackers. Kaspersky provides a vulnerability scan for this purpose, which analyzes apps that require security fixes.

There are also some wonderful additional features. For example the password manager. It’s not as effective as specialized ones, but it’s better than having your information in a file on your desktop. Furthermore, the installer installs Firefox and Chrome add-ons automatically. The add-ons primarily indicate harmful URL links while browsing the web and feature an on-screen keyboard if you believe your machine has been infected with a keylogger.


TotalAV may not be a big brand, but it is one of the finest free antivirus choices on the market for home use. It’s a growing and popular service that takes care of the necessities.

TotalAV offers a thorough Smart Scan, despite the fact that a real-time scan is only available to paying users. It goes above and beyond simply scanning for viruses. The utility also examines starting applications, detects trash and duplicate files that are cluttering your system, and assesses browser security.

They’re releasing a Safe Site plugin for Chrome, Firefox, and Edge browsers to compensate for the lack of real-time protection. It prevents known dangerous URLs from being accessed.

Independent malware labs generally compliment the program. Y ou can be confident that you are receiving the greatest possible performance.

You can even try out the premium version with the free version. You can test the Pro version for nothing after installing the free edition. This enables all of the capabilities you want in your antivirus, such as ransomware protection, real-time protection, and many other enhancements.

Sophos Home

The fact that Sophos primarily targets big firms is the major reason you may not have heard of them. Naturally, the Sophos Home Free edition keeps some of the features that appear to have been directly imported from the company’s business version. Even as a free service, you can remotely control three devices from a single console. This is ideal for friends or family.

Malware Protection and Web Protection are the two primary features of Sophos Home Free. You won’t get any anti-ransomware tools or real-time monitoring, so be extra cautious when downloading questionable email attachments.

Scanning is the primary method used by Sophos Malware Protection. Unfortunately, there is no space for personalization here — the only choice is a thorough scan. This means that if you want to rapidly scan through certain critical areas of your storage, you’ll have to wait until the whole scan is finished. Certainly not a time-saving strategy.

Web Protection is concerned with blocking access to questionable URLs, such as phishing sites. When you try to browse a suspicious website, you see a High-Risk Website Blocked notice. Download Protection starts when the website isn’t prohibited but your download includes harmful malware. It assesses the file based on data supplied by other computers and the reputation of the hosting website.
A Parental Controls tab is also available. There, you may choose the categories of content you want to ban. It’s an excellent choice for parents because you can operate the antiviral remotely from a second device. It contains notifications about filters that certain material has triggered and is compatible with the majority of contemporary browsers.

Overall, Sophos Home provides a basic solution that might be a valuable addition to your family’s protection. Assume you’re the one in your home in charge of controlling everyone else’s gadgets. In such scenario, Sophos Home can greatly simplify these chores. And it will not cost you anything.

Panda Free Antivirus

Panda Free Antivirus is an anomaly in the world of best free antivirus software interfaces that induce anxiousness. Their apps provide one-of-a-kind outdoor sceneries with a beautiful user interface. Nonetheless, despite its odd taste in color palettes, background pictures, and name choice, it’s one of the most competent free antivirus solutions available.

However, the list of features for Windows is far greater than you’d expect. There is real-time malware prevention, as well as the ability to automate recurring system checks and prevent automatic malware installation via USB devices. You may also use your USB drive to create a partition in case your PC doesn’t start up due to infection.

If you have an Android device, you can receive real-time scanning not only for your internal storage but also for SD memory cards. The Privacy Auditor, on the other hand, is one of the most helpful features. One of the most common ways Android applications become infected with malware is through dodgy apps that steal your data owing to authorized permissions. This function examines which applications have access to which features, allowing you to delete those that are requesting access to capabilities that they do not require.

Other useful features include battery optimization and device monitoring, which assists in the recovery of misplaced phones.

Windows and Android users are often the most significant groups that require antivirus software. Panda is an excellent free option for such folks.
