About Kaspersky Security Network

Kaspersky Security Network is an infrastructure of cloud services providing access to Kaspersky's online knowledge base with the following information:

• Reputation of files, websites, and applications
• Categories of files, websites, and applications (for example, an operating system file, computer game, Adult content website)
• Frequency of file detection in all countries of the world and geography of file distribution
• Statistics on how files and websites are trusted by users of Kaspersky applications worldwide (Kaspersky Application Advisor)
• Recalls by Kaspersky AV analysts of individual virus signatures in local databases of anti-virus applications (for example, a verdict changed from "dangerous" to "safe" for a particular object)

Kaspersky Security Network data is used in Kaspersky applications for the following purposes:

• Ensure a faster response by applications to objects whose information is not yet included in anti-virus application databases.
• Reduce the probability of Anti-Spam false alarms.
• Improve the performance of certain protection components.

  For example, the anti-virus application can perform the following actions based on Kaspersky Security Network data:

  • Block user access to malicious websites.
  • Block execution of malicious files on the user's computer.
  • Restrict access to specific categories of files and websites (for example, restrict files and websites of the Computer Games category from being opened during office hours).

If the user participates in Kaspersky Security Network, the Kaspersky application installed on the user's computer receives information from Kaspersky Security Network and sends Kaspersky information about potentially dangerous objects detected on the user's computer to be analyzed additionally by Kaspersky analysts and to be included in reputation and statistical databases of Kaspersky Security Network.
