I think my computer may have been hacked. I'm not 100% sure this is what happened but let me describe the details. Alright, one day I logged on AIM and my friend's screen name was on it with the password remembered. Well I found this odd because he's never logged into his AIM on my computer. On top of this, every time I would scroll through webpages like Se7ensins, the scroll bar would move back to the top and kept repeatingly doing this randomly. Also, some of my keys on my keyboard are locked. For example 6, b, and n don't type along with a list of others for some reason. Well I scanned my computer using Norton Internet Security and all it found was a tracking cookie that I fixed so I don't think it's a virus but there's definitely something weird going on and I need to get to the bottom of it and figure it out so I can keep posting on Se7ens. Right now I'm using a friends computer but I would really like to use my own again so any help is greatly appreaciated. Thanks in advance.
