Carriage Return or Line Break or ALT+Enter in Cell problem

[zubair99]

Why Carriage Return or Line Break or ALT+Enter adding automatically in every excel cell ?
is it a virus or corrupted excel software because I did not put anything its auto adding in every cell ?
I have reinstall office 2013 many times and windows 7 also but same problem every time.
please help thanks.

Is the cell's alignment Wrap Text set to On or Off?
