What Is a Cloud Based Virus Scanner and How It Works

Most people have heard of antivirus software and scanning abilities but may not realize that cloud based scanning can also benefit from these antivirus scanning options. At Comodo, we want to help you understand what they are and how it works so you can make an informed decision as to whether or not it is the right choice for your company.


A Cloud virus scanner is part of antivirus and antimalware technology that uses agent software for the protected endpoint while still offloading most of the data analysis onto the provider’s infrastructure. What that means is that agent software is used that is lighter than traditionally installed antivirus tools to require less strain on your resources.

Instead of having to determine whether a file is malicious by using local analysis, it is sent to the cloud for processing.

How It Works

Traditional antivirus software intercepts objects and files using multiple layers and each layer has to be scanned using various technologies, such as antivirus:

  • Heuristics
  • Rules
  • Signatures
  • Behavioral Analysis, etc.

Because of the redundancy, user experience is affected and can cause a slow-down of productivity.

Our Cloud-based scanner moves the scanning to another location so that you still get the lengthy scan and can keep hackers at bay, but you won’t have to deal with the slower PC or device.

With our product, you don’t have to worry that the endpoint isn’t connected to the internet, which can limit the protection. A cloud virus scanner can help with this because it stores a local cache of queries on the endpoint and can contain the results of earlier queries to make it faster. With our cloud virus scanner, you don’t have to worry. Contact us today to learn more about the cloud virus scanner.
