If you use a cloud service to provide anti-virus to your computers, you don’t need to install anti-virus anymore.

Although, you may need to install a small client on your machines that can communicate with the anti-virus service.

You may hear this referred to as SAAS Software as a service anti-virus. So far, at least three vendors are offering this service to business (not personal) customers including Symantec’s hosted End Point Protection, McAfee SaaS Endpoint Protection, and Web Sense’s Triton Technology.

One of the benefits of this technology is that your computers no longer need to have the latest “signature updates” installed. The latest signatures are, in theory, available in the cloud the instant your anti-virus vendor creates the signature.

Someday your anti-virus may be provided from the cloud too!
