Users get the usual features like system scanning, but there’s an added bonus. There’s the System Watcher feature, which uses machine learning to identify previously unknown malware. And there’s also the Network Attack Blocker, which alerts its users when it detects a suspicious connection on their network connection.

Not all threats will come in malicious software, sometimes having unpatched applications can be exploited by hackers. To that end, Kaspersky offers a vulnerability scan that analyzes programs that require security patches.

Not only that, but Kaspersky also adds several other useful features. For example, you will find a password manager. In addition, the installer is automatically add-on for Firefox and Chrome.

To compensate for the lack of real-time protection, they offer a Safe Site extension for Chrome, Firefox, and Edge browsers. It blocks known malicious URLs, which should prevent malware from appearing on your device.

Independent malware labs are widely praised for this service. AV-TEST certifies it as a superior product and gives it a maximum score in the performance category. So, its users can rest assured that they are getting the best performance.

#14. Sophos Home Free

Sophos Home Free – maybe you have never heard of this antivirus because they mostly cater to businesses. Sophos Home Free has two main features, Malware Protection and Web Protection. You won’t get any tools to fight ransomware or real-time monitoring, so you should be extra careful when downloading suspicious email attachments.

Sophos Malware Protection relies on scanning. Unfortunately, there’s no room for customization here, a full scan is the only option. This means that if you want to quickly scan a few key places in your storage, you will have to wait for the full scan to complete.

Web Protection focuses on preventing access to suspicious URLs, including phishing sites. When you try to access an obscure web page, you get a High-Risk Website Blocked warning. In the case when the website is not blocked, but the downloaded file contains malicious code, Download Protection will start. It evaluates files based on data shared from other computers, and the reputation of the website being hosted, and displays appropriate warnings.

Not only Sophos also provides a Parental Controls tab. There, you can customize the type of content you want to block. Considering that you can manage your antivirus remotely from a second device, this is a good choice for parents. It includes warnings about filters being triggered by some content and will work with most modern browsers.

Overall, Sophos Home has a basic package that can really be a useful addition to family safety. Suppose you are the person at home who manages other people’s devices. In this case, Sophos Home can make these tasks a lot easier. And it won’t cost you at all.

Advantages:

• Parental supervision
• Remote management capability
• Lightweight antivirus software

Deficiency:

• Lock many features
• Weak internet security measures
• No customization for scan options

#15. Panda-Free Antivirus

Panda Free Antivirus – is the best anti-virus application that has a more modern UI. However, despite their unusual taste for color palettes, background images, and odd name choices, this is one of the most reliable free antivirus options you’ll find.

Panda-free antivirus offers real-time malware protection, you can schedule periodic system scans and block automatic malware execution from USB devices. You can also create a partition on your USB drive for extreme cases when the PC won’t boot due to malware.

If you are an Android user, you also get real-time scanning not only for the internal storage but for the SD memory card as well. However, one of the most useful features is Privacy Auditor. One of the most prominent ways Android apps get malware is in the form of cryptic apps that steal your data because of the permissions it grants.

#16. Malwarebytes Free

Malwarebytes Free – is one of the best and most free anti-virus applications to protect users’ devices. If you just need an anti-virus to clean your PC once in a while, Malwarebytes is an excellent tool.

However, users usually use Malwarebytes as an additional antivirus, as it can remove threats that other scanners don’t detect. For example, the program checks the system boot record using a rootkit scanner so that it operates even in the deepest layers of your system.

Malwarebytes Free is a lightweight solution by design that uses few system resources and sacrifices extra features for efficiency. So, suppose you have an older or lower machine. By using Malwarebytes you will get a much lower startup impact compared to other options.

The main problem is that it lacks web protection features. It blocks malicious URLs from the web, but this does not apply to email attachments. So, malicious files that you got through other sources will find no resistance and will end up on your system. This is a concern, so you should use some real-time protection measures like the default Windows Security.

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

Advantages:

• One of the lightest options
• Works well with weaker devices
• Detect malware hidden in deep layers
• Good malware lab results

Deficiency:

• No real-time protection capability
• No additional features
