I try to be so careful about scanning everything I download before running it, but somehow a virus managed to slip though. I just wanted to encourage everyone here to look in your Windows/System folder for a file called 'ddhelp32.exe'. It's a hidden file, so make sure you set Windows Explorer to view them. If you find it, delete it immediately. You should also run 'msconfig' and see if this file is loading at startup (that's how I found it).
