Any thoughts on how much difference paid-for Antivirus (Commtouch) would make in improving malware protection? Specifically we have been hit by malware such as SmartHDD recently.
Also, at some point over the weekend of July 7 (DNSChanger-related?) untangle traffic grinded to a halt, the interface was unreachable, powercycling the HW brought things back. Any thoughts on how to troubleshoot/avoid/understand more about this?
