I think I may be hacked based on a few things that have been happening in the last couple weeks or so. First I have noticed that things are taking a long time to load now when they were noticeably quicker only a week or so ago, my computer doesn't seem right. When I shut down now (not sure if it's because I exit everything so quickly before I shut down) almost every time there is a Waiting for program to close before shutdown message. I also noted something strange 2 days ago when I left my computer on and went for a walk. I was playing an online game and left the game on when I left for my walk, I was gone for maybe an hour and when I got back the game was exited completely and windows media player was running. No one was in the house and it was locked and the monitor was in power save mode (black screen). OS is Windows 7 Home Premium edition.
