Thanks, Palal for your quick response. I tried to install the recommended solution but the phone refuse to accept the sis installation. Furthermore, I tried to manually delete the files but then I could not view the System directory even I re-set my Windows setting to view system file. Now, if I ever dare to touch that directional control again, the auto-plilot ups and down movement will continue until I turn off the phone.

What should we do with these kind of people who wrote the nasty programs? I have many programmers working for me in my software company. None of them would ever have thought to do something like this to harm others, just for the ego trip. It is really not that difficult to write those virus programs. Just like it is easy to put poison into the bottle of medicine for some poor soul to pick it up. Either these kind of people are sick or they have such low esteem of themselves in order to get high on someone's pain.
