Many free antivirus solutions are legal only for personal use, but these programs are fully legal for small businesses.
There is a ton of free antivirus software out there, but most free solutions can’t be used legally by businesses. Popular free antivirus software solutions like AVG, Avast and Malwarebytes are licensed strictly for home computers. If a provider’s end-user license agreement (EULA) prohibits commercial use, implementing the software could amount to intellectual property infringement.
Luckily you don’t have to choose between abiding by the law and saving money. Here are our top choices for free and legal antivirus software solutions, plus some great paid solutions you can try for free.
The cost of cyberattacks can be steep, impacting your business’s bottom line and reputation. Fortunately, keeping your business devices secure doesn’t have to be expensive. In fact, the following three antivirus solutions can keep your business safe — and won’t cost you a dime.
Comodo Internet Security is a complete virus- and malware-removal solution. It detects and protects systems from viruses, malware, spyware, rootkit attacks, bots and more before they can infect your computer. It uses both local and cloud-based virus definitions, so computers are protected even if the software isn’t up to date.
Why it’s different
Unlike most free antivirus solutions with limited capabilities, Comodo provides potent protection at no cost. In addition to scanning, detecting, and protecting systems from viruses, spyware and other malicious attacks, Comodo features an auto-sandbox technology that allows you to safely run untrusted programs. You can also set personalized alerts, lock down computers, and restrict devices to safelisted applications.
Commercial license
Under Section 2.1, the Comodo EULA states that “Comodo Internet Security (CIS) may be used royalty-free for both commercial and personal use.”
How to get started
Download Comodo via the company’s website instantly. No registration or billing information is required. (Mac users can download Comodo Antivirus for Mac.)
You may not know that your Windows PC already comes with free, legal antivirus software: Windows Security. Windows Security offers comprehensive protection against all kinds of malware and viruses. Users can tweak its settings to quickly improve their small business’s cybersecurity.
Why it’s different
Windows Security tries to stay invisible while giving you complete control. Windows Security runs in the background even if you’ve installed no other antivirus software. Its malware and ransomware protection are reasonably good for a built-in program. Additionally, the software has a simple, easy-to-use interface that lets you manually schedule and specify types of scans, toggle real-time protection, and view detection histories.
Commercial license
Windows Security is free to use on a limited number of business laptops and computers. Its EULA states under Section 1b, “If you operate a small business, then you may install and use the software on up to 10 devices in your business.”
How to get started
Windows Security comes with your PC, so you don’t need to download it, register or provide any contact or billing information. Learn more via the Windows Security website.
ClamWin’s open-source antivirus software can remove attachments with viruses in Microsoft Outlook and auto-scan for viruses in Microsoft Windows Explorer. It includes a virus-scanning scheduler and a regularly updated database of all concerning viruses.
Why it’s different
ClamWin’s open-source code means you can tweak its software to fit your needs and preferences. ClamWin is also part of the Free Software Foundation, meaning its free version isn’t a gateway to any sort of paid plan. While it requires checking files manually, you can get a real-time scanner by adding on the free Clam Sentinel companion software. With ClamWin, you get Windows antivirus software that’s easy to operate.
Commercial license
ClamWin operates on the Free Software Foundation’s GNU General Public License, which states, “You are not required to accept this License in order to receive or run a copy of the Program.” As such, any entity may use ClamWin.
How to get started
You can download ClamWin and download Clam Sentinel on their respective sites. You won’t need to enter any information.
