While a resource reduction and automatic updates might appeal to many users it should be noted that an Internet connection is required to make use of the cloud antivirus service. Users without an Internet connection will not be able to test programs and files on their local computer system for malicious code. This can be problematic even for broadband users who are usually online 24/7 if the Internet connection dies because of technical problems.

The real question therefor is if users want to (or can) rely solely on the cloud antivirus concept. The answer should be in most cases “no”. What good is an antivirus software that might stop working during usage because of a dead network card or Internet provider network difficulties.

Would you rely on a cloud antivirus solution?

Update:

Panda Cloud Antivirus stores the signatures and detection information in a local cache as well which means that the computer system is protected even if no Internet connection is available. (thanks Rain for clarifying this)
