How Cloud-Powered Antivirus Works

There are many anti-malware products on the market, but they all perform the same basic function: scan the infected files on your computer and compare them to lists of known malware. Some products use artificial intelligence to learn how to classify unknown files, but other products rely on a database of known viruses and malware.

This week, we’ll be teaching you how cloud-powered antivirus works. We’ll start with how cloud-based antivirus works, which, in all honesty, is pretty simple. The idea is that your antivirus provider will take your data from the cloud and put it back into your device whenever you’re ready to use it.

Unlike traditional antivirus, which is traditionally installed on a device, cloud-based antivirus is designed to be installed in the cloud, hence the name. This allows you to scan all the files on your computer from any computer, not just your own. It can also detect and block malware by inspecting the digital fingerprints that malware leaves behind.

Almost everyone knows the term antivirus and how it works to protect your devices from malware. Most antivirus solutions allow you to install software that runs locally on your computer. You can learn more about the quality of PC Matic and check out some of the features offered by locally installed antivirus programs.

But despite the effectiveness of locally installed antivirus solutions, you can also think about so-called cloud-based antivirus. Let’s take a closer look.

What is Cloud Antivirus?

To better explain what cloud-based antivirus software is, you must first understand what the term cloud means. Simply put, the cloud is a decentralized space where you can store your files, which you can access over the internet. Cloud-based antivirus software protects your device by communicating with an online, cloud-based threat database.

How does it work?

Cloud-based antivirus consists of a small local component (client) installed on your computer and web service components that work together. The main feature of these antivirus programs is that they perform most of their calculations on the Internet and not on your computer. So files that are flagged as malware or virus are stored in the cloud instead of on the hard drive.

This means that the antivirus program does not take up any extra disk space, apart from the small installation files. All this virtually eliminates the resource consumption that most users complain about when using antivirus software.

Web service

The web service on which Cloud Antivirus runs runs on one or more servers on the internet. These servers handle most of the calculations and threaten the data. Depending on the setting you choose, the antivirus program scans your device for threats identified in the web services database.

Most antivirus vendors have a team of researchers who are constantly on the lookout for new threats. In the cloud-based antivirus, these researchers constantly update the list of threats on the cloud-based web service. This means you don’t have to wait for software updates to notify your antivirus software of new threats.

Cloud AntivirusFeatures

If you’ve used another antivirus solution before, the Cloud Antivirus interface will probably look familiar. Not only is it cloud-based, but it also retains its core antivirus capabilities and features, so not much will change in that regard. You will find some of the following features and options:

  • Perform a thorough scan of all folders and applications on your computer.
  • Schedule automatic scanning of specific files and folders
  • View detailed scan results to see which malware or threats were detected and removed during the scan.
  • Take measures against malware and infected files or recover files mistakenly placed in the malware category.

The originality of Cloud Antivirus does not lie in its user interface. Its uniqueness lies in its dual personality, that is, the presence of two separate components – local and online. This allows it to tap into the vast library of malware on the Internet to effectively protect your devices.

Benefits of Cloud Antivirus

  • Your computer is protected by a program that has access to the latest data on threats and malware. Within seconds of the cloud-based antivirus becoming aware of a new threat, your computer will do the same.
  • You don’t need to keep your cloud-based antivirus software up to date. Automatic updates are performed in the cloud.
  • It has a small, resource-efficient client that requires little computing power.
  • Multiple devices can be protected from a central server


  • If the device-based client does not have Internet access, the antivirus program’s ability to protect the user is minimal. This is because it cannot retrieve threat detection information from the cloud.
  • Possible invasion of privacy due to the amount of personal information collected on your device. Most cloud-based antivirus providers assure their customers that no personal data leaves their devices. The idea is that the program only scans certain executables that do not contain personal data.


The best way to find out if cloud-based antivirus is right for you is to try the software and compare the results with your regular antivirus. Most cloud computing antivirus programs offer a free trial. However, as cloud technology evolves, cloud antivirus could be the future of cyber security.
