Participating in Kaspersky Security Network

Kaspersky Free uses cloud protection to make protection of your computer more effective. Cloud protection is implemented using the Kaspersky Security Network infrastructure that uses data received from users all over the world.

Kaspersky Security Network (KSN) is the cloud-based knowledge base of Kaspersky containing information about the reputation of applications and websites. The use of data from Kaspersky Security Network ensures faster responses by Kaspersky Free to new threats, improves the performance of some protection components, and reduces the likelihood of false positives.

Users' participation in Kaspersky Security Network allows Kaspersky to promptly receive information about types and sources of new threats, develop solutions for neutralizing them, and minimize the number of false positives. Participation in Kaspersky Security Network lets you access reputation statistics for applications and websites.

If you participate in Kaspersky Security Network, you automatically send information about the configuration of your operating system and the start and completion time of processes in Kaspersky Free to Kaspersky.
