My computer has gotten slower recently, and I think it might be a virus. I noticed that in the bottom-right corner my little Java logo (coffee cup) isn't on the taskbar anymore. I then noticed when I tried to run limewire it popped up for about a second then would fail to load. After trying to start it about 10 times a Java window popped up saying something about an error with limewire. What exactly does Java do? Could it not running be the reason my computer has slowed down. I made sure the Java stuff was installed, but I don't know how to open it, it doesn't open when it is restarted either. EDIT: I've done a few tests with AVG and it didn't find a virus.
