Free Antivirus Solutions for Small Business

There are several antivirus solutions that are available in the market. Most of them are licensed for personal use only. Small businesses cannot legally use these tools. Some of these antivirus solutions include AVG, Malwarebytes, and Avast. All these are licensed to be used at home and for personal use only.

For instance, the end-user license agreement for Malwarebytes explains that the free version is limited to personal and non-commercial purposes. At the same time, AVG’s EULA explicitly states that any commercial use is prohibited and will violate corporate laws.

But this does not mean that you have to choose between abiding by the law and saving money. Here we have five antivirus software applications that are completely legal to be used by small businesses.

Nano Antivirus

This is an award-winning antivirus software application that operates with proprietary technology in the businesses’ own labs. The software application can be downloaded for Windows and can also be used as a web-based antivirus program. In this way, it allows users to protect the entire system or scan individual files.

Unlike most free antivirus software applications, the tool protects against winlockers, viruses, and even ransomware. The software application also aims to provide speed, reliability, as well as convenience. First, it runs on its own antivirus engine to provide real-time defence for the local systems. This also protects against downloads, as well as web traffic.

The tool also gives its users high-speed scanning, quick updates, and fixes. All these minimize the overall downtime and productivity loss. The tool gives its users the convenience of choosing the type of antivirus protection that best fits their business.

Nano Antivirus has a fairly brief license agreement. Regarding its use, it simply states that the users can use, copy and distribute the application without any restriction.

Comodo Internet Security

This is a complete malware and virus removal software application. The tool is able to detect and protect the different systems from spyware, viruses, and malware. It can also guard against rootkit attacks, bots, and other security breaches that can infect a computer system. The tool uses both local as well as cloud-based virus definitions so that the computer systems are protected even if the software application is not up to date.

There are some features of the application that makes it different from the rest. Unlike most free antivirus software applications, the application has a wide range of capabilities. The application is a completely functional software application that uses enterprise-grade technology at absolutely no extra cost. Apart from the basic functions of scanning and detection and protecting the overall systems from the different viruses and some other malicious attacks, the application has an auto-sandbox technology. This is used to safely run the programs that you do not trust anymore. The tool can also secure the DNS to filter the blacklisted websites in real-time. The tool can also personalize alerts and lockdown computer systems.

Comodo Internet Security can be used royalty-free for both commercial and personal use.

Windows Security

This is a tool that gives comprehensive protection against all kinds of malware and viruses. The tool is currently available only for the computer systems that have this tool by default. You might need some time to change its settings, but this is the best way to improve your cyber security.

The tool stands out from the rest because it tries to stay invisible when it is giving you complete control. Even if the computer has no antivirus installed, Windows security runs in the background. The application provides malware and ransomware protection which is pretty good for most of the built-in programs. At the same time, the software application has a simple and easy to use interface that allows you to manually schedule and specify the types of the scans, view detection histories, and provide real-time protection.  

Windows Security is free to use with a limited number of small business computers. The best part is Windows Security comes with your system, so you do not need to download it.


This is a product from Fortinet which is used to connect your devices to the Fortinet network for security maintenance. Through this connection, FortiClient can identify suspicious files, establish a firewall and protect your computers from malware. FortiClient can be used across several devices or even in a web browser. The application keeps your devices connected and safe even if you are travelling.

The tool is different from the rest of the pack as it is compatible with a single sign-on software application. The application can also streamline its use. The tool is also able to block any unauthorized USB access. The application is also able to secure your devices so that they are defended against any attacks rather than merely reacting. The tool is available under the General Public License.

ClamWin Free Antivirus

This is an open-source antivirus application that can be used to remove attachments with viruses right in Microsoft Outlook. The tool can also auto scan for the viruses in MS Windows Explorer. The tool includes a virus scanning scheduler and a database that is updated on a regular basis about all the concerning viruses.

The factor that makes this different is ClamWin Free Antivirus is open source with a source code. This gives you an opportunity to tweak its software to fit your software needs. The tool is also a part of the Free Software Foundation. This means its free version is not a gateway to any kind of paid plan. With this, you get the windows antivirus software that is easy to operate. ClamWin Free Antivirus operates on the free software foundations, General Public License.
