Hello,
I would suggest you to check Symantec Endpoint Protection 12.1
Latest Symantec Endpoint Protection 12.1 is powered by Insight and is the fastest, most powerful endpoint antivirus software solution you can buy for both virtual and physical systems. Endpoint Protection provides state-of-the-art defense against all types of attacks and seamlessly integrates the essential antivirus security tools you need into a single, high performance agent with a single management console. Endpoint Protection provides leading antivirus protection without slowing you down.
Symantec Endpoint Protection can now detect threats based on a file's characteristics rather than by using Symantec virus definitions only. This behavioral protection reduces management overhead as you do not need to add exceptions for the files that are false positives.
By layering technologies like Insight and SONAR, antivirus scans are reduced and maximum performance is achieved while stopping cyber-criminals and even zero-day threats in their tracks.
Key Features
Unrivaled Security. Blazing Performance. Built for Virtual Environments.
Symantec Endpoint Protection is built on multiple layers of protection, including Symantec Insight and SONAR both of which provide protection against new and unknown threats.

Symantec Endpoint Protection 12.1.2 includes the latest features for improved security, performance and management.
