I have IBM desktop at my home, and access the internet daily. But from past few days i have noticed that some of my files/data have been played with. This is my personal desktop so no one else work on my desktop so i am sure no other user of my PC that did it. So I was shock that if it's really possible that someone over the internet got through my files/data. Some my music files have been renamed 1, 2 and so on. I also resorted to partitioning in order to prevent possible hacking, but the geeks seemed to have intruded my desktop still. Please suggest are there any ways to completely prevent them from this intrusion?. I am very afraid, because of this all things. Help me out.
