I have been having problems with our system. We thought it was just a Backdoor trojan...but we have isolated all of the machines and thoroughly cleaned them. But I am still getting heavy utilization on our system which makes it excessively slow and sporadically decline connections because it exceeds the 4096. I have 15 servers and about 50 client pcs. I have shutdown the VPN to prevent machines not yet cleaned from accessing the system. I do not have a clue which direction to turn at this point. I am running mcAffee AV on all the machines. Any help would be great. I am looking into a Fluke One Touch tool to possible help but justifying the cost to management is always a challenge. Thank you in advance for your assistance.
