Creepy lines

How i can delete this lines? Its very hard 2 extrude with them. Tripple clicking x,y,z doesnt help. With any new extrusion this lines appear again. How i can dispose of them?

Those creepy lines are axis lines. It is telling you which way the extrusion will go.

If you don’t want to see them, just extrude a little, click to end that function, then hit G to move the extruded segment around.
