Internet Gateway icon disappears

For some reason or other the Beta 2 Antivirus product causes the internet gateway icon in the notification area to come and go as it pleases. I have 2 computers where this happens. To test it out, I uninstalled CAVS from one and, sure enough, the icon came back and stayed. The problem doesn’t affect connectivity at all, but I find it annoying. Has anyone found a way around this or is it a bug?
