Microsoft could do the same to other publishers and offer antivirus based on the Cloud, that is the analysis of which is antiviral deported on Microsoft servers.
Expected shortly in beta, Morro, Antivirus free successor to Windows Live Onecare could according cloud computing. The principle of this new generation of Antivirus is to interconnect the client installed on the workstation with a data center managed by the publisher.
Cloud of virus already proposed by Panda, Trend Micro and McAfee.
This solution was adopted to fight against the continued growth of bases of signatures and the use of local resources. Concretely, this translates to the following process: opening a suspicious file triggers the sending of a request (with imprint and vector) to the data center hosting the Antivirus engine and a full database of signatures.
If the code is identified as malicious, a warning message informs the user. Changes in the parameters of the workstation can also be proposed to prevent infection and developed an anticode.
This real-time protection not herald the end of traditional signatures. This technology is presented as complementary rather than a substitute.
Several antivirus vendors, including Mcafee, trend Micro and panda security have implemented since 2008 this new technique. It is however not the case according to Kaspersky that this approach has to many limitations.
