Ultimate Guide to the 5 Best Small Business Antivirus


No business is too small for an online presence. A website and social media accounts increase a company’s exposure and interaction with customers, and company emails and network systems help organize and utilize customer and company data in ways that can be essential to success.

Greater opportunities include greater risk though, and for any internet user – especially entrepreneurs - there are threats around every corner that you need to detect and defeat if you want to safeguard your business.

There are a number of antivirus software providers for small businesses to choose from. How do you know which one is right for your business? In this guide, we'll take a look at how antivirus software works and who are the top 5 providers of this essential layer of security.


Cyber Self-Defense 

Small businesses are becoming a bigger target every day, as hackers look for prey that lacks the massive security infrastructure of major corporations and government and defense agencies. According to research carried out by IBM in 2016, small businesses are targeted in 62 percent of all cyber-attacks launched every day.

Many infections are the result of errors that let attackers in. Before investing in antivirus and security solutions, you need to first train employees in cyber self-defense – don’t click on any links or download anything that seems suspicious, don’t visit dodgy websites, don’t click on pop-up ads, and don’t use thumb drives whose origin you can’t vouch for are a few basic policies that should be implemented immediately in any business looking to stay safe.

Once you’ve implemented operational security, it’s time to invest in a solid antivirus and security system that can stop threats that get by even the most cautious targets.

Small Business Antivirus Software

Cyber security today works almost as a sort of cat-and-mouse game. Security companies track and catalogue new viruses every day around the clock, adding them to software databases, which are updated to tackle the new threat – until a new virus is deployed.

There are two major areas in which antivirus software should be judged: how they protect the system in real time as files are saved, and their detection of viruses.

Methods of Threat Detection

There are a number of methods of threat detection, with signature-based detection traditionally one of the most common. Signature detection keeps a record of the malware in a database for future detection, though this can be sidestepped once hackers modify the viruses. Other methods, like sandbox detection and data mining, check a program’s actions and use algorithms to determine if they pose a threat.


Today’s anti-virus software protects users from malware, Trojans, worms, and other threats - and you don’t need any IT experience or professionals to help install or manage it.

Most of today’s anti-virus software can be managed from a central console – either on-site or in the cloud – allowing you to keep a handle on things no matter where you are.

With today’s ease of operation, you should be able to easily find security software that even a novice can install, and which you can operate even if you’re far from the office.


Today’s security software has been adapted to fit the variety of devices on the market today, including PCs, laptops, tablets, and smartphones. Some services can even track stolen devices and remotely wipe them of all data, keeping sensitive information out of the wrong hands in event of theft.

Software Plans

The typical small business security software plan is meant to be intuitive and easily adaptable to the business’ needs. Most software charges by device annually or monthly, with the operator able to add or subtract devices as needed. Typically the monthly fee per device drops as the term of service extends and the number of devices increases, so it may make better economic sense for you buy a yearly package rather than pay by month.

One warning though - there can be billing issues. Some providers automatically renew their subscriptions without prior approval needed, and often require advance notice if the customer wants to cancel, potentially leading to unexpected costs after one has moved to a different security program.

The market is also flooded with free antivirus software, which can be a solid way for users to test out the software before purchasing. As a long-term solution though, it typically makes more sense to invest in paid antivirus software, which provides more features and better protection, as well as round-the-clock customer service in most cases. Paid service can also be a lifesaver in an event of an infection, providing virus removal and clean-up, and trained representatives to walk you through the process – in some cases with a money-back guarantee if they can’t rid your system of the virus.

Due to the extreme threat posed by cybercrime, it’s wise to invest the money needed to stay safe, especially considering how much you paid to get the company started in the first place.

Online Protection

Today’s security software can supply users with online protection, including a built-in firewall that will keep out threats while online, as well as email protection that scans messages to filter out spam, spyware, and phishing attacks. In addition, antivirus software companies offer parental control options, to allow users to protect their children from dangerous content online.

Simply put, you can find software to protect you from threats that reach your company online, and which also provide safeguards for your family at home. The best antivirus will also offer online protection to fight malware in real time. Many new viruses are more sophisticated than in the past so it’s recommended to use more than one program to help ensure no viruses slip through the cracks.

On top of real-time scanners many of the best antivirus programs use pre-boot virus scanners to search for problems without interference, thus making it much more likely to be caught and removed. If pre-boot and real-time scanning fail to identify all viruses the final option is to do a clean install - which deletes everything from your hard drive. While this is obviously an extreme action to take, it is the best way to guarantee 100% that all viruses are removed.

Common Problems with Antivirus Software

One headache often caused by antivirus software is “false positives”. This is when the software classifies something benign as a threat. If the program is setup to automatically quarantine or delete said files, it can cause real problems and potential loss of data or even network access if certain essential systems are red-flagged by the security software.

Another common problem is that security software can slow down your computer’s performance. Make sure that your antivirus software is updated and that you’re only running one security software program at a time, so things don’t get sluggish. If performance speed is of paramount importance, look for a software provider known for being efficient, and easy on operating systems.


If your data is stolen, hackers can hold it for ransom or use customers’ financial data to clean them out. A number of security software products offer encryption services, which automatically encrypt all files on the device’s hard drive and/or all data stored in the cloud so that even if it is compromised, you can keep it from being exploited.

Industry Favorites

Though the world of cybercrime is constantly evolving, there are a number of industry leaders who can provide the right cybersecurity solutions for any small business.

The Bottom Line 

Securing your business against cyberattacks can protect you from a career-destroying attack, or at the very least, costly cleanups and lost customer data.

When choosing an antivirus software, you first must consider what your needs and that of your company are. Do you need a product best suited to only a handful of computers, or one built to safeguard dozens or hundreds? Are you most concerned about threats faced by employees while browsing the internet, or by malicious attacks sent to your company email, website, and servers?

If you’re a tech novice who is easily intimidated by all things computer-related, it may make more sense to go with the company that has the easiest user interface and provides the very best customer service, so they can walk you through any incidents that may arise.

Pricing can also be a concern - especially for a small business - but it is an investment that is essential to the well-being of your company.
