When we have McAfee VirusScan V4.5.1 monitoring continually in the background we notice a considerable slowdown in TestStand performance. I'm not sure why performance slows, since we load all VIs into memory at the beginning of the test, so I would assume it's not scanning the VI every time TestStand makes a call to it.
Has anyone else run into this problem and found a way around it? I previously had the virus scan disabled and only had it run overnight, but our IS department wants it running all the time.
