"Cloud" is definitely one of the IT sector's most popular marketing words of recent years. The virtual clouds promise you easy and mobile access to data and services. The anti-virus sector has also come to use this technology. Fast scans and very low resource usage are clear advantages of cloud-based scanners. But, as usual, there are two sides of the coin.
...

We believe that combining a cloud service with a conventional anti-virus scanner offers the best of both technologies. This is why many Emsisoft products use cloud features.

First of all, Emsisoft Anti-Malware offers the possibility of participating in the "Emsisoft Anti-Malware Network". If you enable this option, all decisions regarding alerts from the behavior blocker are directly submitted to our server. This enables other users to see if the majority of the community allows or blocks a program and thus helps you to make a decision. There is also a "trust index" for every program based on statistical calculations. Programs that are definitely safe are put on a whitelist, and there will be no further alerts for this program

Emsisoft Anti-Malware's scanner also asks if you would like to submit suspicious patterns in newly discovered files (only program files, no documents). Our analysis team then analyzes the suspicious file thoroughly and creates a new signature if need be. This helps Emsisoft and also all users by reducing the response time in the event of new malware outbreaks and offering the best protection possible.

Our HIPS-based firewall Emsisoft Online Armor also uses the Emsisoft Anti-Malware Network. Saved rules for allowed and blocked programs are submitted to the Emsisoft cloud in order to reduce future alerts. False alerts are avoided in an efficient manner without lowering the security level.

Incidentally, all data on program files stored in the Emsisoft Anti-Malware Network is visible to everyone and even searchable. The Emsisoft cloud is thus not closed, but absolutely transparent and can be accessed through a website as an interface at any time. There are currently more than 12 million known program files (as of November 2012), including geographical distribution of malware occurrence.
