what is sonar protection
SONAR is a real-time protection that detects potentially malicious applications when they run on your computers. SONAR provides zero-day protection because it detects threats before traditional virus and spyware detection definitions have been created to address the threats. SONAR uses heuristics as well as reputation data to detect emerging and unknown threats. SONAR provides an additional level of protection on your client computers and complements your existing Virus and Spyware Protection, intrusion prevention, and firewall protection.
