I installed Ubuntu 12.04 LTS in Windows 8.1 using vmware workstation. When I open a file in the terminal using vi filename.c, the arrow buttons will not work properly, pressing up arrow prints A, down arrow B, right arrow C,left arrow D. How can I overcome this problem?

Your Shift key is probably stuck.

This can happen because either the keyboard key switch is physically stuck a bit or because the last time you released the key the system did not properly detect it.

Both causes should get eliminated by hitting the key a few times.

It's perfectly normal behaviour that the key combinations Shift+↑, Shift+↓, Shift+→ and Shift+← in a terminal window result in the characters A, B, C and D to be printed.
