I recently bought a new imac. It is starting to run extremely slow. When I do anything on the computer it can take up to 5 minutes. Just to get the dock to pop up takes several minutes. Even to type a letter on a document will take awhile. I am not sure what is happening. This just happened all of a sudden. I don't use the Internet very often, so I would be very surprised if it was a virus. Anybody have any ideas of what is going on?
