Does NOD32 AV 4 scan any TCP/IP traffic other than HTTP traffic on ports 80, 8080, and 3128 (I think those are the three)? Here's really the underlying issue. I upgraded all of a client's computers from v2.7 to v4 and ever since are having intermittent issues with SIGNIFICANT sluggishness in an application. They are a payroll processor and the application is their enterprise payroll application (a client server app). I need to know if there is anything in v4 that would be scanning network traffic for viruses when they are submitting queries to their database through the payroll application. Any help/ thoughts are sincerely appreciated. Thanks in advance!
