Please,help me.I don't know how this happened and it is really strange.Everything was good with my hard drive but now the last time I opened my pc I noticed something really odd.In ''My Computer'' folder my Local Disk icon had changed.Instead of being an icon that displays a disk,it is an icon that displays something like a crab!What is that?!Is it some kind of virus?!How can I change it to the default icon?!
