Malwarebytes has been a go-to solution for removing malware since 2006—and one that works on just about any platform you can imagine.

Malwarebytes (formally known as Malwarebytes Anti-malware) scans and removes any malicious software that may be lurking on your system, and actually scans in batch modes rather than sifting through individual files that are open.

Malwarebytes also includes its own endpoint protection security solution, and varied layers of detection technology, to match its layered approach to security. This multi-vector approach to protection ensures that your network, devices, and important files are kept out of harm's way.

The cloud platform delivers Malwarebytes Endpoint Protection via a single unified endpoint agent.  This leads to the instant deployment and management of this service. 

Because Malwarebytes Endpoint Protection is delivered via a single unified endpoint agent, you'll be able to instantly deploy and manage the cloud platform.

If you're interested in trying Malwarebytes for yourself, you can check out the free trial, which offers instant access to its endpoint protection (with full functionality for up to 100 endpoints.) Once you're ready to take the plunge, just reach out to the Malwarebytes sales team for a quote.

Best cloud antivirus FAQs

Which cloud antivirus is best for you?

When deciding which cloud antivirus to use, first consider what your actual needs are. Budget software may be kinder to your wallet but may also provide a relatively limited set of tools, so if you need to use advanced options you may find a more expensive security platform is much more worthwhile. Additionally, higher-end software can usually cater for every need, so do ensure you have a good idea of which features you think you may require from your cloud antivirus.

How we test

To test for the best cloud antivirus we first set up an account with the relevant software platform, then we tested the service to see how the software could be used in different situations, and from different types of device.
