Thanks. We'll let you know when a new response is added.

If I understand ‘cloud antivirus’ correctly, it’s a matter of collecting checksums of the files on your system and comparing them against the stored signatures of malicious files in the cloud.  That having been said, there are two benefits I can see compared to ‘traditional’ antivirus:

1) the cloud is always up-to-date, so you don’t need to worry about not having the latest signatures downloaded,
2) there can be terabytes worth of signatures online, where that obviously would not be reasonable to have on your local system

    What is your current anti-virus program and on what scale it it used. Is it standalone, network or other? How many devices and what types are you looking to support? What OS platforms are they running?

    There are lots of benefits of using cloud antivirus such as it will scan your PC even if the antivirus is not installed in your PC. There is no need to update the version on a regular basis as it is on the auto update mod,

    I do not see major benefits apart from the Antivirus scanning your PC even if the software hasn't been installed on your PC.

    Cloud antivirus companies make use of locally functioning application and generates a signature. After this it requires a web service to define where the data files are malicious or not. A cloud antivirus does not use disk space for storing the information. One thing to remember while using a cloud antivirus is that for redundant protection the PC must be always connected to the Internet.

    I still prefer a local AV program over the cloud. The reason for my choice is I think the cloud is going to be the next major target of a hack or breach. It seems like everyone wants to putt all their eggs in one basket. One crack and it all comes down.

    What is your use case? What your specific risks and/or needs? Cloud-based malware protection from vendors such as Webroot is becoming more and more popular. The footprint is smaller, the detection rates are better, and the overall threat mitigation capabilities can beat out traditional malware protection. Is this what you're looking for?

    No installation required on your computer. It won't take up hard disk space so no need to update your data files hosted on the cloud and you get the latest in protection when it becomes available.
