After a security breach, 37% of small to medium-size businesses “suffered a financial loss, 25% filed for bankruptcy, and 10% went out of business,” according to the National Cyber Security Alliance (NCSA). A malware attack can prevent your devices from working or slow them down to the point that they’re unusable. Furthermore, a breach may result in stolen data and deleted files, all of which can devastate your business. 

Malware consists of ransomware, spyware, and viruses. Hackers continuously develop new ways to attack vulnerabilities in internet-connected devices, making comprehensive malware protection and removal software crucial. Many solutions protect devices and remove malware, including all-in-one security systems and free malware removers. We compared more than 30 applications by looking at the main features, devices covered, and ease of use. Plus, we scoured customer reviews and the latest independent tests to determine the quality of protection and support services.

Malwarebytes free and paid versions offer advanced protection that’s best for Windows.

You can use Malwarebytes on all devices, but you must manually install the software, as there’s no central console unless you purchase one of two top-tier plans. 

The free version differs from premium configurations by only scanning for potentially unwanted programs (PUPs) and malware on-demand or according to a schedule, like once per day. In contrast, premium versions scan in real-time in the background and also provide anti-ransomware and anti-exploit features.

Deploy your malware protection and removal software by accessing the keycode in your management console and then sending an installation link or email. According to Webroot, it takes 30 seconds to install.

Having your devices disabled or data deleted can force you to stop operations and spend a massive amount of time and money to remove malware. Business security solutions work in the background by observing application behavior and continually scanning for the latest threats. 

Although many good solutions exist for malware protection and removal software, Norton 360 delivers a robust security solution for all devices in and outside of your office, making it great for companies with remote employees as well as on-site staff.

What Is Antimalware Software?

Antimalware software protects your devices from all kinds of malware, including spyware, rootkits, ransomware, and viruses. It uses various machine learning, heuristic, and artificial intelligence to track your applications and detect suspicious behavior. Antimalware software often provides tools for removal, and in some cases, these tools are very advanced so you can reverse the effects of malware or access files stolen and held for ransom. 

Does Antivirus Remove Malware?

Yes, antivirus software can remove malware. However, antivirus software relies on definitions of virus types to identify and remove malicious actors from your devices. By comparison, some antivirus software has antimalware built-in. Antimalware goes beyond definitions to identify intruders, such as behavioral learning or artificial intelligence. These tools monitor your system by looking for suspicious behavior. This advanced technology is necessary because it can often catch totally new and unknown malware before your antivirus software has a definition for it. 

What Does Antimalware Protection Cost?

Antimalware protection is affordable, and many free plans exist. For paid plans, you can expect to pay anywhere from $15 to $85 per device per year plus tax. It’s essential to check the renewal price because most malware protection and removal software charge a higher renewal fee. Renewal prices can increase your cost by up to 50% after the first year of service. 

If you already use antivirus software, you can look for less expensive security solutions focusing only on malware. Examples of these are free versions of Bitdefender or Malwarebytes. Or you can add a security suite along with your existing antivirus software and use two programs to monitor similar things. 

How Does Antimalware Software Differ From Antivirus Software?

As mentioned above, antimalware catches the latest infections by continuously monitoring your system for suspicious activities, even if it’s a new and unknown threat. On the other hand, antivirus software acts as a protective measure to prevent a virus from being downloaded to your computer. But it doesn’t typically use the high-tech machine learning or behavior-based tools found with antimalware. However, many companies now bundle antivirus and antimalware technologies into one solution.
