Nokia Ovi Suite 1.1
Invasive rubbish. It's bloatware and doesn't have the option to turn the synchronising off. This means it'll send data transfer requests to your mobile phone every now and then--even if you've turned the main interface off. Why? Because the blasted thing keeps running in the background and you can't even turn it off in Task Manager in Vista--the processes keep restarting themselves. Basically, it won't let you decide when to turn the software on and off and when to synchronise with your phone. I just uninstalled it and will go looking for a better piece of basic Bluetooth software right now.
