What is cloud-based antivirus?

Cloud antivirus is a security program that keeps the malware information in cloud-based servers rather than on your device. Traditional antivirus uses your device’s processing power to work, which can adversely affect the processing power.

Instead, you will need to install a small client program on your network that will connect to the antivirus provider. It will monitor all the software activity, analyze that data and send countermeasures instructions to your device.  A cloud-based antivirus will proactively keep an eye on your entire network and act to prevent potential malware infections.

How to choose the best cloud antivirus?

It is essential to choose a suitable antivirus for your needs, but the numerous options available can be overwhelming. The cloud-based option has made the decision even harder. Here are some of the most important things you need to consider.

Your antivirus needs

An antivirus is a crucial tool to detect and protect you from malware, viruses, Trojans, and ransomware. However, the antivirus needs will differ depending on the number of the device, email traffic, network size, etc.


What is your budget, and how far are you willing to stretch? An affordable antivirus subscription can offer sufficient protection for domestic and small business users. Nowadays, you can find reliable providers such as Panda and Avira that charge a few dollars. This small investment will give you the peace of mind that comes with antivirus protection.

On the other hand, larger organizations with more extensive hardware will need a broader antivirus package. Due to sensitive data and numerous devices at risk, you should consider comprehensive options like Kaspersky and Sophos.


Last but not least, you should consider the features an antivirus offers. Antivirus with more features will require bigger systems. However, a lightweight option like Avira will use less RAM, power, and storage space.

Weighing up your budget against your security requirements and hardware will enable you to get the antivirus that suits your needs. Bear in mind that you can always start with the free trial before subscribing.

Why should you use a cloud-based antivirus?

Advanced malware detection

If your devices have a malware infection, they can affect your entire network. With the traditional antivirus, you will have to download the software on your device to prevent imminent threats. However, you can do this remotely with a cloud-based solution stopping malware before they infect your network. In addition, it does the scanning automatically in real-time, so you will always remain protected.  

Reduces strain on the processing power

Traditional antivirus software that you have to install on your device can significantly slow it down. Besides, you will have to scan and update the software, which is time-consuming manually. However, failure to do so can put you at risk of malware infection. On the other hand, a cloud-based antivirus uses cloud technology and machine learning, which does not need human intervention.

Improved efficiency

Cloud-based antivirus improves protection and efficiency because it works from a central server. Plus, virus updates and scanning are done automatically and in real-time. This helps to significantly decrease the waiting time between discovering a threat and neutralizing it. 

All-around protection

You may think you don’t need an antivirus solution because you are careful online. Although you should always be cautious online, an antivirus is an essential security layer. For example, you can compromise your security if you load a webpage when your browser has a zero-day vulnerability.

What is our take on cloud antivirus?

We have looked at some of the best cloud-based antiviruses to make it easy for you to choose the right one. The biggest question is whether the cloud antivirus is the best solution for your business. Compared to traditional antivirus solutions, a cloud antivirus’s main advantage is the lower impact on systems.

Cloud vs. traditional antivirus – what is the difference

It is vital to have antivirus on your device or network to prevent harmful malware. However, deciding between a cloud-based and a traditional solution may be a bit difficult. Which one is the best?

Traditional antivirus

A traditional antivirus works by scanning files and checking them against a virus database. It will eliminate any threat to keep you safe. However, there is a lag between identifying a threat and taking action. Also, hackers are using sophisticated methods to launch attacks on devices. 

Furthermore, an antivirus should be up-to-date with virus definitions to work optimally. With traditional software, you have to update it manually. This means new emerging viruses can easily bypass it and attack your device or network.

Cloud-based antivirus 

A cloud-based antivirus is a solution to the above issues. The virus definitions are stored on the provider’s servers instead of your device. So, it will not require your device’s processing power to check for threats. 

More importantly, cloud-based options use AI technology to scan in real-time. This means there will be no lag for a hacker to exploit between threat identification and action. 

Is cloud-based antivirus as effective as traditional antivirus?

Cloud-based solutions require an internet connection to offer complete real-time protection, which is a potential weakness.

It is a fact that cloud antivirus relies on the internet for its functionality. This means that a malware or virus that disconnects the internet can cause a malfunction.

Another major issue with cloud-based antiviruses is offline protection. How safe is your device or network when offline? Unlike before, the latest versions of most cloud antivirus offer protection even when you are offline.

All the antivirus packages we have on this guide use innovative technology to keep an offline record of threats.so, those criticizing cloud-based antivirus solutions are not up to speed. The cloud antivirus is evolving rapidly and now offers the best protection when both online and offline. 

The biggest priority for small and medium-sized businesses is uptime and productivity. A cloud-based antivirus will keep you safe against malware or virus infections without straining your hardware resources. Moreover, since it works automatically, your team will concentrate on priority tasks, thus increasing productivity.


Neither the cloud-based nor traditional antivirus is 100% breach-proof. Also, a cloud-based option is more efficient and reliable even more than the most experienced IT team. Nowadays, cybersecurity threats are evolving at a rapid rate to rely on manual practices. A well-established provider will maintain a high protection level and improve your security.


Cloud antiviruses are evolving at a rapid rate and may soon replace mainstream antiviruses. With a cloud-based solution, you can manage all devices and information centrally. Also, it carries the scanning process on the cloud instead of installing it on your device.

We have looked at some of the market’s most reliable cloud-based antivirus services. Many of them provide support for regular consumers and businesses. Go further and explore their websites for information before settling on any provider.


A cloud-based antivirus solution is a way to go to protect against malware and viruses. It is powerful and requires fewer resources to offer complete protection against any threat, even emerging ones. So, choose a cloud-based antivirus if you want to remain safe always.

Yes. The files you send to the cloud server may contain a virus that can potentially infect the servers. Besides, viruses can infect your device or network if you download such files from the cloud. Therefore, ensure you scan all data before downloading to be on the safer side. A reliable cloud services provider should put sufficient security measures to prevent malware infection.

Preferably, you’d want an antivirus that effectively cleans and removes the infected files. A cloud antivirus will act in real-time to move the infected file into quarantine. This will help to prevent the infection from spreading. From here, the software will remove the suspicious files or delete them completely.

A traditional software program will slow your device’s performance, especially during scanning. However, the story is a little bit different with a cloud antivirus. The software is cloud-based, so it will not interfere with your device’s performance. Besides, it carries out its functions in real-time, offering you protection all the time.
