McAfee has a very effective gateway solution (hardware) as Yuki pointed out. You will find it one of the better ones in raw detection and network security. I do prefer the URL scanning capabilities of Fortigate, but I like the McAfee Gateway for raw detection of new threats. I ran into a problem with Norton 2015. On two (of 12) machines here it actually 'disappeared', the ICON disappeared. When I ran a check to see if it was working I could download malware test files without them being validated with Download Insight.. This was corrected on restart of the machine, but alarming to me when an AV suddenly 'disappears' from operating.. Anyone have any suggestions? For now I moved back to Trend 2015 until I can get a ticket into Norton, or find what is causing this. Also I want to test a newer version of Trend under a heavy workload environment. Not to derail, but as expected, Trend is as light as a feather if you follow my procedure of doing a full-scan, waiting 30 minutes, rebooting, then using the machine. I need to figure out why Norton was 'killed' on two machines.. I've verified these machines are malware free, and one of them is a fresh-install.. Strange. Frank has a point - I think all of us used Norton has a punching bag.. But it seems to be rapidly changing.
