I have a problem with my PC. Before 2 days ago, i was chatting in a X web-page. I saw a man, using my nickname. And i told him to delete that. After a few minutes when I came back, i saw myself with that nickname who was using by X person. I dout that anyone is checking my PC. I know that i disconnected from that page, and when i came i saw myself login in. Strong! My question is: What to do in this case?! I have the txt information what hicakthis found. If anyone of admis will tell me how to do, it would be nice, cos', as i told, someone in checking my PC!
