Server Antivirus (Free & Paid) - 7 Strongest Bodyguards in the Club

Today, IT system includes a complex infrastructure of various devices. While it's paramount to secure all of them, one of the most critical components of your ecosystem is often overlooked - server. Just one malicious file or process can spread throughout the business network, making potentially devastating impacts on corporate operations.

You need nifty, reliable server antivirus that protects without draining system resources, so their ecosystem stays secure and available.

Most importantly, you don’t want to use a generic one-size-fits-all antivirus solution on your servers. If there's antivirus explicitly made for your server software, use that.

It may cost little more, but it's worth it since that generic solution isn't going to offer you much protection.

Searching for free antivirus protection, willing to pay for broad antivirus coverage across all your servers, or need to remove a virus from your workstation? Here's where to begin.

What is Server Antivirus Software?

It’s software used to provide virus protection to servers, that connect to business networks.

It plays a vital role in corporate security by helping to ensure the business network and critical systems are safeguarded from malware and virus, which is one of the most common types of attack.

The fact is servers are “ripe for the harvest” when it comes to cyber-attack. Recently, there has been a surge in Linux-based malware directed at IoT systems and cryptocurrency mining.

What Does It Do?

Since most businesses have various technology stacks that run some combination of Windows, Linux, and/or AIX - it's crucial to approach security with a holistic view that goes beyond Windows scanning to protect other platforms against viruses, malware threats, and worms.

At a high level, server antivirus systems help you to:

  • Keep data safe from viruses - Avoid the chance of a security breach causing major corporate disruption by identifying and removing viruses;
  • Stay one step ahead - Leverage a comprehensive set of virus signatures that automatically becomes current with the latest virus enhancements to keep your business safe;
  • Identify emerging issues - Go one step beyond using virus signatures to reveal new viruses before they make the damage.

What Protection Your Server Needs?

Many of the same types of malware that attack endpoints can make their way into your server, including these common threats.
  • Viruses that delete or corrupt data;
  • Zero-day attacks that find vulnerabilities in an ecosystem and strike the same day;
  • Ransomware that encrypts the data and holds it hostage until the user pays a ransom.
Still, attacks on servers can be even worse. When an attack targeting servers succeeds in placing the virus in the system, the following things could happen.
  • The virus stays “quiet” and discover a place to hide in the system;
  • Once situated, the virus will search out all network vulnerabilities;
  • Accessing those vulnerabilities, it’ll disable network security measures and start infecting server or servers.
Once activated by their CnC (command-and-control servers), the malware will extract data from the network and send it to the CnC server.

This is how the login info for every user on a bank’s server is stolen, how millions of personally identifiable information fall into the wrong hands and how hackers steal cyberwarfare secrets from the National Security Administration.


Antivirus for the server has so many benefits; some of them are as following:

Strong performance - Good antivirus, fills corresponding server resources, optimizes antivirus checking method and eliminates trusted practices from scanning, which all raise the product’s working and lesser the quantity of computing resources crucial to perform antivirus scans.

Reliability - In the event of a breakdown or mandatory shutdown, the app usually restarts. It happens to ensure stable system safety while the diagnostics system discovers the reason for the collapse.
Real-time antivirus protection and scanning - Robust anti-virus examines all records that are opened, used, or customized and purify or deletes all contaminated files. Also, doubtful data or a document is isolated in a quarantine section before to experience advance study.

Positive safety against new viruses - Best antivirus software offers more efficient safety techniques vs. malicious programs. The smart analyzer detects with a great extent of chances any malicious attack in programs, even if their name isn’t included in the antivirus record.
