• Comprehensive virus scanning: Beyond the standard full system sweep, we valued those antivirus programs offering the flexibility of quick or custom scans, catering to the user's unique needs and system demands.
• Anti-malware protection: Beyond just computer viruses, the best antivirus software should protect against a variety of malware, ranging from rootkits to more elusive vulnerabilities.

Who it’s best for

Bitdefender GravityZone Small Business Security is a holistic antivirus solution, standing out as the top choice for small businesses looking for ransomware protection for their Linux-based systems. It has comprehensive protection measures that are suitable for small- to mid-sized enterprises desiring to safeguard their assets from a myriad of cyberthreats. Plus, it has a user-friendly interface and a wide range of security features that novice and tech-savvy employees can navigate easily, making it ideal for SMBs.

What we liked

Bitdefender GravityZone excels with its intuitive user interface, state-of-the-art anti-malware tools, and real-time defensive measures, bolstered by a firewall. It is capable of scanning systems and networks for viruses and malware. The fact that the antivirus solution supports a wide range of Linux distros, from Ubuntu to Amazon Linux, also adds to its appeal. GravityZone lets you determine what internet traffic to allow or block, as well as configure policies and add rules. More importantly, Bitdefender has solid ransomware protection due to its behavior-based monitoring capabilities, thanks to its great detection skills powered by machine learning (ML). This means it can flag any suspicious activity, even the most difficult threats.

From the dashboard, we loved how easy it is to view any detected threats under the Threats Xplorer feature, which centralizes detected threats from your network, devices, storage, firewall, or anti-malware solution. This feature helps you stay on top of your company's security. Additionally, you can view your risk score under Risk Management and get an overview of your network security, seeing any vulnerable apps and endpoints with misconfigurations, including the top user behavior risks like weak passwords, for example.

We also loved another cool feat we discovered — the Sandbox Analyzer. This lets you analyze threats in a sandbox, so you can investigate them safely without infecting your systems. Plus, security heads will appreciate how easy it is to search for hashes and plug-in MITRE ATT&CK; techniques.

What we didn’t like

Despite its strengths, we didn’t like that custom scans required specific target directories and lacked a straightforward "scan entire machine" option. This can be problematic during urgent situations, by slowing down response times and potentially allowing threats to linger and escalate, which may impact users' data security and business operations.
