I am updating the antivirus software on a client's domain network. They are currently using AVG. I used Blink Personal a long time ago and thought it would be a good solution. Blink purports to protect against most 0-day exploits and has a vulnerability assessment feature similar to Secunia. The Retina software can run the vulnerability assessment from the server on all IPs (depending on license) as well as connected devices (routers, printers, etc.). Is this a good recommendation, or is there something better?
