Sluggish internet and Works

A month or two ago we signed onto DSL service and of course installed a firewall also -- the free ZoneAlarm firewall -- although that follwed a few days later. Since then we have suffered through a progressively slower internet, so now it is slower than it had been via modem! Also, Microsoft Works is now as slow as molasses, even worse than the internet. I have noticed that the TangoManager and vsmon.exe together comprise 100% CPU usage always when you look in the Task Manager Processes (although each one's percentage fluctuates by the second or so). I suspect this isn't all that is causing us misery, but I know so little about these things...

Here is my HijackThis log:
