My computer was starting to act weird, so I went to youtube and read information on how to remove viruses, worms, etc. Someone said to go to start, then run and type in cmb and write Q: and like a fool this is what I did. Now I have a hard drive named Q. I tried to remove it, but it says that it is hidden. What could I do to remove it. Also, how would I remove viruses from my computer if I have them? I tried to restore my computer and it does not allow me to.
