Microsoft is currently alpha-testing its upcoming anti-virus product, according to industry sources.
The sources claim that the anti-virus software works as a behaviour blocker that monitors different events and actions on computers. If the event or action is typical of a virus or is harmful, it will be prevented.
Behaviour blockers do not use code signatures like traditional scanner-based anti-virus programs, so they may be able to protect against new types of viruses without being updated.
The anti-virus product was also referred to as an Intrusion Detection and Protection System by sources, indicating that it may work in conjunction with the Windows firewall.
An interesting feature of Microsoft’s anti-virus software is that it is distributed, according to the sources. It communicates with other machines over a secure channel and learns from these.
