The VCOM SystemSuite NetDefense Firewall is causing momentary annoying pauses on my PC. This is especially noticeable while playing videos and games. The pauses occur about every 2 seconds and last about a second. As soon as I turn off NetDefense the pauses stop, and then the videos and games run smoothly. When I activate the Windows Firewall the pauses also do not occur. I'm using WinXP Home. How can I correct this behavior?
