Well, can ye stand one more question, fellahs?

Ever since trying to download a certain firewall, I have had problems. My "MY Computer" takes a full minute or more of the flashlight searching before it shows me my drives, etc. When I try to open the kerio firewall (not the one that caused the original problem) I get a message which says "unable to initiate FwDrv Driver:2." Okay two questions...what does that one mean and I reinstalled my scanner software, but when I try to open it, I get a message that it cannot open because some other program is busy and to click on "Switch to" to close that program. If I click on Switch To, it takes me to the Start Menu, which I used to get to the scanner software to open it! When I click on Ctr-alt-Del, the only thing running is the scanner program I am trying to open. Help, please?!
